10 Best AI Search Optimization Tools in 2026 (Free and Paid, Compared)

Quick comparison

The best ai search optimization tools

#1

SE Ranking

Best for: Small agencies and in-house teams who want a full SEO suite with AI visibility included from about $103/month

★★★★★★★★★★4.7/5 on G2 (1,619 reviews, checked Oct 2026)

Visit seranking.com

Starting price$129/month (Core, billed monthly; $103.20/month billed annually)

Free planNo — 14-day free trial

SE Ranking is the value pick in this list because the entry Core plan does not feel like an entry plan: 2,000 keywords tracked daily, a full site audit, keyword and backlink research, and AI visibility tracking across five engines. For a small agency or an in-house team, that is the whole SEO workflow plus AI monitoring in one subscription, and the per-keyword cost is the lowest of any suite here.

The trade-off is polish. Reviewers like the depth but some report small accuracy differences against the bigger suites, and the interface takes a few days to learn. If you want the cheapest route to daily tracking and AI visibility together, start here; if you need the largest backlink index, look at Semrush instead.

What we like

• AI visibility tracking across 5 engines (ChatGPT, Gemini, Perplexity, Claude, Google AI Overviews) included on Core — 25 prompts a day
• 2,000 keywords tracked daily plus site audit, keyword and backlink research in one plan
• White-label reporting and guest links for client work, with an Agency Pack add-on from $69/month

Watch out for

• Some G2 reviewers report occasional minor discrepancies in rank-tracking accuracy and search-volume estimates versus larger competitors
• Reviewers note the interface can feel less intuitive, and complex reports take getting used to

#2

Peec AI

Best for: Marketing teams and agencies that want clean daily AI visibility reports across the main answer engines

★★★★★★★★★★4.7/5 on G2 (21 reviews, checked Oct 2026)

Visit peec.ai

Starting price$95/month (Starter, billed monthly; $80/month billed annually)

Free planNo — 7-day free trial

Peec AI does one job and does it cleanly: it runs your prompts across the answer engines every day and turns the results into reports a marketing manager can read without an SEO dictionary. Visibility, position, sentiment and share of voice share one view, with source analysis showing which domains the AI answers quote. Setup takes minutes, and unlimited users mean the whole team sees the same numbers.

The limit is engine choice. Self-serve plans cover three engines, so if your buyers also ask Claude or Perplexity, you will pay for add-ons or move to Enterprise. Peec reports the gap rather than closing it: the recommendations point at the work, but the writing and fixing stay with your team. For a mid-market team that wants honest daily numbers, it is the best dedicated tracker here.

What we like

• 50 prompts tracked daily across 3 engines of your choice, with visibility, position, sentiment and share of voice
• Unlimited users on every plan, so the seat math favors teams and agencies
• Source and citation analysis shows which domains AI answers actually quote

Watch out for

• Only 3 of 6 engines on self-serve plans — Perplexity, Claude and others cost extra or need Enterprise
• Shows where you stand but gives limited guidance on what to fix; G2 reviewers flag unclear recommendations

#3

Otterly.AI

Best for: Small teams and solo marketers who want the cheapest serious start in AI visibility tracking

★★★★★★★★★★4.7/5 on G2 (54 reviews, checked Oct 2026)

Visit otterly.ai

Starting price$29/month (Lite, billed monthly; $25/month billed annually)

Free planNo — free trial

Otterly.AI is the cheapest serious way to start tracking AI visibility. The Lite plan covers 15 prompts a day across ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot for $29 a month, and the GEO audits check whether your own pages are crawlable and citable in the first place. Unlimited team members and a clean dashboard make it easy to hand the numbers to a client or a manager.

The limits show up fast. Fifteen prompts cover a first pilot, not a real brand, and the next plan jumps to $189 a month. Gemini, AI Mode and Claude sit behind paid add-ons on every tier, so the real price depends on which engines you need. Start here to prove the channel matters, then move up when the prompt list outgrows Lite.

What we like

• Lowest entry price here: 15 prompts tracked daily across ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot
• GEO audits check whether your pages are crawlable and citable by AI engines, plus prompt research and recommendations
• Unlimited team members on every plan, with API and MCP access from Standard

Watch out for

• Gemini, Google AI Mode and Claude are paid add-ons on every plan — Claude costs $29/month extra on Lite
• 15 prompts run out fast, and the next plan jumps to $189/month

#4

Semrush

Best for: Teams already paying for Semrush who want AI visibility added to keyword research, audits and backlinks

★★★★★★★★★★4.4/5 on G2 (4,304 reviews, checked Oct 2026)

Visit semrush.com

Starting price$99/month per domain (AI Visibility Toolkit, billed annually; 25 prompts tracked daily)

Free planYes — free account (limited AI Visibility metrics; 10 tracked keywords)

Semrush is the deepest bench in this list, but its AI visibility is sold separately from the SEO suite. The standalone AI Visibility Toolkit costs $99 a month per domain and tracks 25 prompts a day across ChatGPT, Google AI, Gemini and Perplexity, with prompt research and an AI-readiness audit. Semrush One Starter at $199 a month adds the full SEO toolkit and raises the allowance to 50 prompts a day.

Watch the plan you are on. The $139.95 SEO plan tracks no AI prompts at all, so a team that buys it expecting AI visibility pays twice. Extra users need their own AI Visibility license, and extra prompts cost $60 a month per 50. Buy Semrush when you need the research depth behind the AI data; buy a dedicated tracker when you only need the AI numbers.

What we like

• Tracks brand mentions across ChatGPT, Google AI (AI Overviews and AI Mode), Gemini and Perplexity, with prompt research and an AI-readiness site audit
• Semrush One Starter ($199/month, $165.17 billed annually) bundles the toolkit with the full SEO suite and 50 prompts a day
• 27-billion-plus keyword database, site audits and backlink analysis behind the same login

Watch out for

• The $139.95/month SEO plan includes no prompt tracking — AI visibility costs $99/month per domain on top, or $199/month for the bundle
• Extra users need their own AI Visibility license, and extra prompts cost $60/month per 50

#5

Surfer

Best for: Content teams who want every article scored for Google rankings and AI citations while they write

★★★★★★★★★★4.8/5 on G2 (546 reviews, checked Oct 2026)

Visit surferseo.com

Starting price$59/month (Discovery, billed monthly; $49/month billed annually)

Free planNo — 7-day money-back guarantee

Surfer is the tool writers open beside the draft. Its Content Editor scores each page in real time against the pages ranking now for the target query, flagging the terms, headings and structure that are missing, while the AI Tracker shows whether AI engines cite the page once it is live. For a team that publishes every week, that loop — write, score, publish, check the citation — is the whole AI search workflow in one place.

The catch is the tier. Discovery at $49 a month billed annually has no AI prompt tracking at all; AI visibility starts on Standard and only reaches all five engines on Pro. Document caps also bind on the lower plans. Buy Surfer when content is the bottleneck; buy a tracker when measurement is.

What we like

• Content Editor scores drafts in real time against the pages ranking now, with a separate AI Tracker for citations
• Pro ($182/month billed annually) tracks 50 AI prompts daily across ChatGPT, Perplexity, Google AI Overviews, AI Mode and Gemini
• Topical Map, content audits and auto-optimize turn the editor into a full content workflow

Watch out for

• Discovery has no AI prompt tracking — AI visibility starts on Standard ($119/month billed monthly, 25 prompts, weekly refresh)
• Document caps bind on lower plans, and G2 reviewers say the score can push writing toward formulaic copy

#6

Frase

Best for: Solo writers and small content teams who want research, drafting and AI visibility tracking in one tool

★★★★★★★★★★4.8/5 on G2 (311 reviews, checked Oct 2026)

Visit frase.io

Starting price$49/month (Starter, billed monthly; $39/month billed annually)

Free planNo — 7-day free trial (no credit card required)

Frase covers the whole loop in one place: it pulls the top results for a keyword, builds a brief from their headings and questions, drafts with AI, and scores the result for both classic search and AI visibility. The dual SEO and GEO scores sit side by side in the editor, and site audits rank the fixes across your live pages by likely payoff. Starter costs $39 a month billed annually, which makes it the cheapest content-plus-tracking option here.

The limits are scope and scale. Starter tracks two engines, so full five-engine coverage needs the $239-a-month Scale plan, and ten articles a month will not cover a busy editorial calendar. AI drafts still need heavy editing and fact-checking, and white-label reporting is Enterprise-only. For a solo writer or a small team, it is the best value in this list.

What we like

• Dual SEO and GEO scores in the editor, with AI visibility tracking across ChatGPT, Perplexity, Gemini and Google AI from Starter
• Site audits score every page for Google and AI answers, rank the fixes, and draft the improvements
• One agent covers research, drafting, publishing to WordPress, Webflow and Wix, and decay monitoring

Watch out for

• Starter covers 2 engines; full five-engine coverage needs Scale ($239/month billed annually)
• Starter caps at 10 articles and 50 audit pages a month, and white-label reporting is Enterprise-only

#7

Nightwatch

Best for: Small agencies that want unlimited seats, white-label reports and AI citation data in one tracker

★★★★★★★★★★4.7/5 on G2 (64 reviews, checked Oct 2026)

Visit nightwatch.io

Starting price€99/month (Starter, billed monthly; €79/month billed annually)

Free planNo — 14-day free trial

Nightwatch is built for teams: unlimited seats come with every plan, white-label reports start on Professional, and the Starter plan tracks 500 keywords daily for €79 a month billed annually. Its standout feature is Citation Intelligence, which ties each ranking change to the AI citations behind it in ChatGPT, Claude, Gemini and Perplexity. Local tracking runs to ZIP-code level across more than 107,000 locations.

The pricing curve is the thing to watch. The jump from 500 keywords to 7,500 costs €499 a month, so a growing agency should price the next tier before committing. Nightwatch is priced in euros, which US buyers should note. Pick it when seats and AI citations matter more than raw keyword volume.

What we like

• Citation Intelligence links each ranking change to AI citations in ChatGPT, Claude, Gemini and Perplexity
• Unlimited seats on every plan, including the trial; white-label reports from Professional up
• 500 keywords tracked daily with ZIP-code-level local tracking across 107,000+ locations

Watch out for

• Price climbs steeply with keyword volume — €499/month for 7,500 keywords
• No free plan, and keyword-research runs are capped at 100/month on Starter

#8

Advanced Web Ranking

Best for: SEO agencies tracking thousands of keywords across many client sites who also need AI visibility

★★★★★★★★★★4.3/5 on G2 (22 reviews, checked Oct 2026)

Visit advancedwebranking.com

Starting price$139/month (Pro, billed monthly; annual billing discount available)

Free planNo — 7-day free trial

Advanced Web Ranking has tracked rankings for more than 20 years, and the Pro plan shows it: 7,000 keyword units for $139 a month, unlimited projects and users, and coverage of more than 4,000 search engines plus AI visibility across ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews. Every rank check stores the SERP behind it, so any position can be audited later.

Two honest caveats. A keyword unit is one keyword checked weekly on one engine and device, so daily tracking costs more units than the headline suggests. And the interface feels dated next to newer tools, with white-label reports and API access held for the $279-a-month Agency plan. It is a workhorse for high-volume agencies, not a beauty contest winner.

What we like

• Pro includes 7,000 keyword units for $139/month, with unlimited projects and users
• AI visibility across ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews on the entry plan
• Tracks 4,000+ search engines, and every rank check stores the SERP behind it

Watch out for

• A keyword unit is one keyword checked weekly on one engine and device, so daily tracking costs more units than the headline suggests
• Interface feels dated next to newer tools, per multiple G2 and Capterra reviewers

#9

Scrunch AI

Best for: Mid-market and enterprise brands that want AI monitoring plus page audits and AI-agent traffic data

Visit scrunch.com

Starting price$250/month (Core)

Free planNo — 7-day free trial (no credit card required)

Scrunch is the most complete monitoring platform in this list. Core covers four engines — ChatGPT, Perplexity, Google AI Overviews and Copilot — and beyond mention tracking it adds page audits, hallucination detection that flags where AI answers get your brand wrong, and an Agent Experience Platform that serves AI-optimized versions of your pages to AI bots. It also tracks AI agent visits, so you can see which crawlers actually read your pages.

The price and the refresh cadence are the trade-offs. Core costs $250 a month, the highest self-serve floor among the dedicated trackers here, and new prompts run daily for only 14 days before dropping to every 72 hours. Sitecore acquired Scrunch in June 2026, so the standalone roadmap is less certain than it was. Pick it when audits and agent traffic matter as much as mentions.

What we like

• Four engines on Core — ChatGPT, Perplexity, Google AI Overviews and Copilot; AI Mode and Claude need Enterprise
• Page audits and hallucination detection flag where AI answers get your brand wrong
• Agent Experience Platform serves AI-optimized versions of your pages to AI bots, and tracks AI agent visits

Watch out for

• New prompts run daily for 14 days, then every 72 hours by default — not daily tracking
• Highest self-serve floor among the dedicated trackers here, and Sitecore acquired Scrunch in June 2026, so the standalone roadmap is less certain

#10

Profound

Best for: Enterprise brands that treat AI search as a core channel and need the deepest answer-engine data

★★★★★★★★★★4.5/5 on G2 (1,133 reviews, checked Oct 2026)

Visit tryprofound.com

Starting priceCustom quote (Enterprise; free 7-day trial with 50 prompts a day)

Free planNo — free 7-day trial (50 prompts a day)

Profound is the enterprise benchmark for AI visibility: prompt-level tracking, citation analysis, sentiment and competitor views, with up to nine engines on Enterprise. Its AI Marketer agents go beyond reporting, drafting the content fixes and new pages the gaps call for, while agent and crawler analytics show how AI bots read it. Profound says its dataset covers 1.5 billion real user conversations.

The catch is access. The $99 Starter and $399 Growth plans ended in September 2026, so brands now choose a free 7-day trial or a custom Enterprise quote, with no number to budget against before talking to sales. Agencies can still buy Agency Growth at $99 a month plus $399 per client. G2 reviewers call it expensive with a steep learning curve, but for a large brand where AI search is core, it is the deepest tool here.

What we like

• Up to 9 answer engines on Enterprise, including ChatGPT, Perplexity, Google AI Mode, Gemini, Copilot, DeepSeek and Claude
• AI Marketer agents draft content fixes and new pages from the visibility gaps they find
• Agent and crawler analytics show how AI bots read your site, alongside prompt-level tracking

Watch out for

• No published price for brands since the $99 Starter and $399 Growth plans were removed in September 2026 — every deal starts with sales
• G2 reviewers call it expensive and note a steep learning curve for new users

Finding the best AI search optimization tools starts with a simple question: where do your customers actually discover you now? For a growing share of them, the answer is no longer a list of blue links. They ask ChatGPT, Perplexity or Google's AI Mode a question and read the answer, often without clicking anything. The tools in this list exist for that shift: they track whether AI engines mention and cite your brand, and they help you fix the pages that get ignored.

We sorted the 10 tools below by what you actually need, not by brand size: dedicated AI visibility trackers first for teams that only need measurement, then all-in-one suites that bundle AI visibility with the rest of SEO, then content tools that earn the citation itself. Prices are the starting price for the AI search job, checked October 31, 2026.

What an AI search optimization tool actually does

An AI search optimization tool does two jobs. First, it measures: it runs your prompts through ChatGPT, Gemini, Perplexity, Google AI Overviews and the other answer engines, and records whether your brand is mentioned, cited or recommended — and which sources the answer used instead. Second, it helps you act: it flags the pages AI engines cannot read, the questions you never answer, and the competitors who win the citations you want.

The measurement job matters because the shift is already large. McKinsey found that about half of Google searches already show an AI summary, and half of consumers polled now intentionally seek out AI-powered search when making buying decisions (McKinsey, "New front door to the internet," October 2025). A tool in this category is the instrument that tells you whether you are visible in that new front door — or invisible in it.

The tools differ in where they stop. Dedicated trackers measure and report. Suites add rank tracking, audits and research. Content tools rewrite and score the pages themselves. Most teams need one tracker and one content tool, not three of either.

Dedicated AI visibility trackers

These four tools do one job: tell you how you show up in AI answers. Peec AI and Otterly.AI are the self-serve options, Scrunch adds audits and an agent-experience layer, and Profound is the enterprise platform the category is measured against. None of them is a general SEO suite — you will still need a rank tracker or a suite alongside them if you want keyword and backlink data.

The trade-off is focus. A dedicated tracker gives you prompt-level data, sentiment and share of voice across engines, usually within minutes of setup. What it will not do is fix the pages: the recommendations stop at the report, and the writing, technical fixes and outreach stay with your team. Buy one of these when measurement is the gap — when you already know what to publish but cannot see whether AI engines notice it.

All-in-one suites with AI visibility built in

Suites bundle AI visibility with the SEO workflow you already run. SE Ranking includes AI visibility tracking on its entry Core plan, so a small agency gets rank tracking, audits, research and AI monitoring for one subscription. Semrush sells AI visibility as a separate $99-per-domain toolkit, or bundled into its Semrush One plans. Nightwatch and Advanced Web Ranking are rank trackers first, with AI citation and visibility tracking included on their entry plans.

The math that decides this group is simple: if you already pay for a suite, use its AI layer before buying a dedicated tracker. SE Ranking's Core plan is the cheapest route to both worlds in this list. If you only need AI visibility and already own rank tracking, a dedicated tracker is cheaper than a second suite.

Content tools that earn the citation

Trackers tell you where you stand; content tools change it. Surfer scores each draft against the pages ranking now and tracks whether AI engines cite it, while Frase pairs SEO and GEO scores in the same editor and audits live pages for decay. Both assume the same thing: AI engines cite pages that answer the question directly, with clear structure, facts and sources.

These tools fit teams that publish every week. A single article optimized in Surfer or Frase costs less than a month of a dedicated tracker, and the citation it earns is the asset the tracker then measures. They are a weak buy on their own for teams that never publish — if no new pages go live, there is nothing to score.

AI visibility: what to check before you pay

Four details decide whether an AI visibility plan is good value, and all four hide behind the headline price. First, engine coverage: several tools track only three or four engines on the entry plan and charge extra for Gemini, Claude or AI Mode, so count the engines you actually need. Second, prompt volume: entry plans range from 15 prompts a day to 125, and the jump to the next tier can triple the price. Third, refresh speed: daily tracking catches a visibility drop the day it happens; checks every 72 hours, as Scrunch does after the first two weeks, will not. Fourth, the per-domain question: Semrush charges its AI toolkit per domain, so three brands cost three times the headline price.

If your customers find you through our AI search optimization service, the same checks apply: ask which engines are tracked, how often, and what counts as one prompt before you sign. And before you pay for any tool, make sure AI crawlers can actually read your pages — our free AI crawler robots generator builds the robots rules that let them in.

Quick comparison: tool type by need

How to choose the best AI search optimization tools: a short decision path

1. List the engines your customers use. ChatGPT and Google AI Overviews cover most buyers; add Perplexity, Gemini, Claude and AI Mode only if your audience is there. A tool that charges extra per engine can double in price fast.
2. Count your prompts. Write down the 20–50 questions buyers actually ask, then match the list to a plan. Otterly.AI's 15 prompts fit a first pilot; Peec AI's 50 fit a real brand.
3. Decide tracker, suite or content tool. If you already own a suite, use its AI layer. If you only need measurement, buy a dedicated tracker. If you publish weekly, a content tool earns the citations the tracker measures.
4. Check the refresh and the fine print. Daily tracking, per-domain pricing, white-label reports and API access all sit on different tiers — confirm them on the pricing page, not the homepage.
5. Trial it on your real prompts. Every tool here has a free plan or a trial. Run your own questions for a week and compare the answers against what you see when you ask the engines yourself.

Mistakes to avoid

• Buying the cheapest plan without counting engines. Gemini, Claude and AI Mode are paid add-ons on Otterly.AI, Peec AI and Frase — the real price is the plan plus the engines you need.
• Comparing monthly prices without checking billing. Annual billing cuts 15–20% at most vendors here, and Profound has no self-serve price at all since September 2026.
• Paying per domain without noticing. Semrush's AI Visibility Toolkit is $99/month per domain, so tracking three brands costs $297/month before the SEO suite.
• Treating a visibility score as exact. AI answers change with prompt wording, location and model version, so read the trend over weeks, not a single day's number. Our guide to how to get cited in ChatGPT explains what the engines actually quote.
• Tracking without fixing anything. A tracker that reports a gap for six months while no page changes is a subscription, not a strategy. Pair it with content work — see how to rank in AI Overviews for the page-level fixes that move citations, and compare the wider field in our best AI SEO tools guide.

How we chose

We checked each vendor's own pricing page on October 31, 2026 and recorded the starting price exactly as shown, including the annual-billing figure where the page lists one. Ratings come from G2 pages opened the same day, except Scrunch, whose G2 page could not be opened — so no rating is shown for it rather than an unverified one. Four pricing pages (Profound, Peec AI, Scrunch and Otterly.AI) could not be opened directly because the browser service rate-limited those requests; those prices are corroborated from multiple independent October 2026 checks of the same pages and from vendor-provided pricing on G2. We ranked the tools by fit for the most common buyer — a small team or agency that wants to be mentioned and cited in AI answers — not by brand size. No vendor paid for a place in this list, and none of the links here are affiliate links.

What to do next

Start with the decision path above: list your engines, count your prompts, and pick tracker, suite or content tool. Then take the free plan or trial of your top pick and run your real questions for a week — if the answers match what you see when you ask the engines yourself, you have your tool. If you'd rather have this set up and read for you, request a free SEO + AI visibility audit and get a ranked fix list in 2 business days.
