AI brand monitoring tools tell you what ChatGPT, Perplexity, Gemini and Google’s AI features say about your brand when people ask about your category: whether you are named, how you are described, whether the facts are right and which sources the answer relies on. For a growing share of buyers, that answer is the first impression of your brand, and nobody at your company wrote it.
This guide compares the tools built for that job, with the list prices on each vendor’s site on 29 September 2026. We make one of them, Mencoro, and have described the others as we would want ours described.
What to monitor in AI answers
- Presence. The share of runs in which you are mentioned for the prompts that matter, per engine and country.
- Framing. Whether you are recommended, compared, listed or mentioned in passing, and with what sentiment. Our note on AI brand sentiment covers how that is scored.
- Accuracy. Prices, features and claims the answer attributes to you. Outdated facts travel from old pages into new answers.
- Sources. The URLs the answer cites, yours and third parties’, which are the levers you can actually pull.
- Competitors. Who appears next to you and how your share of voice moves against theirs.

Mencoro
Mencoro was built around how a brand is mentioned, not just whether. Each mention in ChatGPT, Perplexity, Google AI Overview and AI Mode is classified into one of five mention types and scored for sentiment, which feeds a positivity index per engine and per competitor, and a share of voice weighted by both. The full answer and its cited links are stored, so you can read what was said and where it came from. Pricing is per check from €15 a month with unlimited projects, competitors and users. See AI brand monitoring for the details.
Profound
Profound monitors visibility, sentiment and citations on up to nine engines and adds agent analytics that show how AI crawlers and agents visit your site. It is sold to enterprises through a demo after a free 7-day trial, and G2 reviewers point to the price as the main drawback.
Brandlight
Brandlight targets Fortune 500 brands and global agencies, with a cross-brand, cross-region command center, source impact scores, technical health monitoring and publisher intelligence. There is no public price or trial.
Evertune
Evertune treats brand monitoring as a statistics problem. It runs each prompt up to 100 times per model to produce an AI Brand Index, word associations and consumer preference data, on 11 engines including base models without live search. Pro is listed at $800 a month and bought through a demo.
Peec AI
Peec AI tracks visibility, position, sentiment and share of voice daily, and includes brand perception and fact-checking views next to strong source analytics. Starter costs €85 a month for 50 prompts on three models you choose, with unlimited users.
Otterly.AI
Otterly.AI offers a brand visibility index, mention coverage and link citation analysis from $29 a month for 15 prompts on ChatGPT, AI Overviews, Perplexity and Copilot. Larger plans add the API, the MCP server and AI crawler analytics.
Scrunch
Scrunch, now part of Sitecore, pairs monitoring and citations with its Agent Experience Platform, which serves an optimized version of your site to AI agents on Enterprise plans. Core costs $250 a month for 125 prompts on four engines, one country and one language, with a 7-day trial.
Similarweb AEO Intelligence
Similarweb’s AEO Intelligence tracks 150 prompts for $129 a month ($99 billed yearly), for one user, on ChatGPT, AI Mode, Gemini and Perplexity. Its advantage is context: AI visibility sits next to the AI referral traffic Similarweb already estimates for your site and your competitors’.
Ahrefs Brand Radar
Brand Radar starts from a large index of AI answers that Ahrefs collects across the market, so you can look up any brand without setting up prompts first. The index costs $199 a month per platform or $699 for all six, and Ahrefs plans include a few custom prompts for your own tracking.
AthenaHQ
AthenaHQ tracks sentiment and share of voice on 11 models on its $295 Starter plan and has a free plan with 300 credits on five engines. Its Enterprise plan adds claim review and discrepancy detection, aimed squarely at catching what AI gets wrong about you.
How to set up AI brand monitoring
- Write the prompts your buyers ask, not the ones that contain your name: “best X for Y”, “X vs Y”, “is X worth it”. Add a few branded prompts to check facts.
- Add the competitors that appear in those answers, including the ones you do not consider competitors yet.
- Pick a cadence and keep it: weekly by default, daily when something is at stake.
- Review the sources monthly. When an answer turns negative or wrong, the cited page is usually where the fix starts.
