Disclosure: This is an independent editorial ranking based on the criteria below. The #1 spot is a sponsored placement a listed tool can claim — it is always clearly labelled Sponsored and kept separate from the ranking. Prices are each tool's own, read in November 2026; tools that don't publish a price are marked demo- or quote-led, and all figures are indicative.
Tracks how your brand appears in AI answers via prompt tracking plus an AI Visibility Index that needs no setup, measuring mention frequency, AI links to your pages and share of answers vs competitors on Ahrefs' real user-prompt data. Full value needs a paid Ahrefs plan.
An AI-search monitoring and optimisation platform tracking brand mentions, citations and sentiment in AI answers, plus prompt research, content audits and GEO recommendations. It has the lowest published entry price in the category, making it a strong SMB / solo pick.
An AI-search analytics platform tracking brand visibility, position and sentiment across AI answers, with prompt suggestions, source analysis and reporting. It has separate brand and agency plans and emphasises multilingual, multi-country tracking (claims 4,000+ brands and agencies).
Surfer (formerly Surfer SEO) is now an AI-search visibility platform: a content editor with live AI-search and SEO guidelines, content audits and competitor gap analysis, plus brand-mention tracking across AI tools and an Agent Analytics beta.
An AEO/GEO platform for monitoring and improving brand presence in AI answers, with competitor intelligence, hallucination detection, a content-action module and an 'Ask Athena' copilot over your own data. It has a genuine free tier plus paid plans that unlock more engines.
Semrush offers AI-visibility, AI brand-sentiment and a free AI visibility checker within its platform, positioning 'AI visibility and SEO in one'. It tracks whether brands get mentioned or recommended across major assistants — convenient for teams already standardised on Semrush.
What an AI-presence audit tells you
A good audit shows, quickly, whether AI assistants mention your brand, how often and for which prompts, the sentiment, whether they cite your pages, and who gets cited instead. It's a diagnostic snapshot — enough to decide if you have an AI-visibility problem worth solving, before you buy an ongoing tracker.
Free and instant options
Several tools now offer a free or no-setup starting point: Ahrefs Brand Radar's AI Visibility Index needs no configuration, Peec AI and Surfer offer free GEO/AI audits, Semrush has a free AI visibility checker, and AthenaHQ has a genuine free tier. These are the fastest way to a first read without committing budget.
How we ranked them
We weighted speed to first insight and a free or cheap entry first, then engine coverage and audit depth. Ahrefs Brand Radar's zero-setup index leads; Otterly gives a cheap but full audit; Peec and Surfer offer solid free reports; AthenaHQ's free tier and Semrush's checker round out the no-cost options.
From audit to action
An audit is a starting line, not a strategy. Once you see the gaps — prompts where AI ignores or misrepresents you — move to ongoing tracking and the content and citation work that closes them. Use the audit to prioritise, then pick the tracker or content tool that fits your scale.
Frequently asked questions
How do I audit my brand's AI search presence?
Run your brand and key prompts through an AI-visibility tool that reports mentions, citations and sentiment across ChatGPT, Perplexity and Google AI. Several offer a free or no-setup audit, so you can get a snapshot before committing to a paid plan.
Is there a free way to check my AI visibility?
Yes. Ahrefs Brand Radar's AI Visibility Index needs no setup, Peec AI and Surfer offer free GEO/AI audits, Semrush has a free AI visibility checker, and AthenaHQ has a free tier. They're the quickest no-cost first read.
What should an audit cover?
Whether AI assistants mention you, for which prompts, with what sentiment, whether they cite your pages, and which competitors are cited instead — across the engines your buyers use. Depth and engine coverage vary, so match the audit to what you need to decide.
Audit vs ongoing tracking — which do I need?
Start with an audit to see if you have a problem; move to ongoing tracking once you're actively working to improve, since AI answers change over time. Many tools offer both a free audit and a paid tracker.
How much do audit tools cost?
Several are free to start (Ahrefs index, Peec/Surfer reports, Semrush checker, AthenaHQ free tier); paid depth starts around $29/mo (Otterly). Figures are each vendor's own, read November 2026.
