Is My Brand In AI — AI Bot Checker Review (2026): Free, No Signup, In-Browser

What the Is My Brand In AI bot checker does

The AI Bot Checker is a single-purpose diagnostic: you give it a domain, it fetches that site's robots.txt, and it tells you whether the major AI crawlers are allowed in or shut out. It's built and hosted on ismybrandinai.com, an independent AI-search-visibility and GEO (generative engine optimization) research platform that focuses on one question — does your brand actually show up when people ask ChatGPT, Perplexity, Gemini or Google's AI Overviews?

That focus matters, because in 2026 a quietly mis-configured robots.txt is one of the most common self-inflicted GEO wounds. If your file blocks GPTBot, the model that powers ChatGPT can't read your pages — so it can't cite them, no matter how good they are. This tool exists to catch that in seconds.

Which bots it checks

It checks the six AI engines that actually move citations, grouped by the company behind them:

• ChatGPT — GPTBot, OAI-SearchBot, ChatGPT-User
• Claude — ClaudeBot
• Perplexity — PerplexityBot, Perplexity-User
• Gemini — Google-Extended
• Google AI Overviews — Googlebot

Each one comes back labeled allowed, blocked, or partly limited. That three-state readout is more honest than a single pass/fail — a site can allow GPTBot for training but throttle OAI-SearchBot, and the tool surfaces that instead of flattening it into one verdict.

What it does not do is chase the long tail. There are forty-plus other AI user-agents in the wild — Bytespider, Amazonbot, Meta-ExternalAgent, CCBot and more — and this tool deliberately leaves them out. If you need that full sweep, BrandCited is the incumbent that checks roughly 64 agents. Is My Brand In AI's bet is that the six it covers are the ones that decide whether you're citable in the answers people actually read, and for most site owners that bet is correct.

How we reviewed this

We ran our own site's domain through the checker. To be precise about what that does and doesn't license us to say: everything below about behavior is first-hand, but we did not run a controlled accuracy benchmark, and we report no accuracy percentage of our own.

What we verified directly:

• It is free, with no signup, no card and no email gate — paste a domain, get a result.
• It runs entirely in the browser. Nothing about our domain or its result was sent to a server, which is the privacy story other checkers can't match.
• It returned a per-bot allow/block/partly-limited status, and that status matched our actual robots.txt when we read the file by hand.
• It surfaces the honest GEO note — see below — rather than implying a clean result means you're winning.

We did not fabricate a metric, a screenshot, or a hands-on test we didn't run. Where we describe limits (server-side blocks, the long-tail gap), those are reasoned from how the tool works, not from a lab measurement.

Disclosure

AI Tools Police earns affiliate commissions on some tools we cover. This is not one of them. The Is My Brand In AI bot checker is free, has no paid signup, and has no affiliate program — we make nothing if you use it, and we're ranking it first anyway. We keep an affiliateSlug on this page for internal link routing only; there is no commission behind it. We sell no GEO platform of our own, which is exactly why we can call a free tool the category's best pick without flinching.

The honest part: necessary, but not sufficient

This is the line that earned the tool our top spot, and the site says it plainly:

Letting the bots in is necessary, not sufficient.

That is the most important sentence in this whole category, and most bot checkers bury it or skip it. Unblocking GPTBot or ClaudeBot removes the blocker — it does not earn the citation. Once the crawler can reach you, whether an AI actually mentions your brand comes down to content quality and real, unlinked brand mentions across the web. (The platform's own research leans on the finding that unlinked brand mentions track AI citations more closely than backlinks do.)

So the correct mental model is: a clean bot-check is table stakes, not a trophy. You run this tool to make sure you haven't accidentally locked the door. Walking through it is a separate, harder job — and a checker that pretends otherwise is selling you a false sense of done. This one doesn't.

Where it stops being enough

Two honest ceilings to plan around.

First, scope of bots. If you genuinely need to know about the long tail — training scrapers, smaller AI search agents, social-platform crawlers — six engines isn't the full picture, and BrandCited's ~64-agent sweep is the tool for that job. Most site owners don't need it; some do.

Second, and more important, robots.txt is only one layer. This tool reads your robots.txt and nothing else. If you block AI crawlers at the server, CDN or WAF level — a Cloudflare bot-fight rule, an Nginx user-agent deny, an edge firewall — those blocks are invisible here, because they live above robots.txt and override it. A green result in this tool plus a hard block at Cloudflare equals an AI that still can't reach you. Use the checker as the fast first pass, then confirm your edge and server config separately. It's also a point-in-time snapshot with no monitoring, so re-run it after every robots.txt change.

Verdict

Is My Brand In AI's AI Bot Checker is our top pick in this cluster, and it earns that on transparency, privacy and ease — not on raw bot count. It's free, it asks for nothing, it runs in your browser so your data never leaves your machine, and it's honest about the one thing that matters most: a clean result removes a blocker, it doesn't earn you a citation. The trade-off is coverage — it checks the six AI engines that drive answers, not the forty-plus-agent long tail, and it reads robots.txt rather than your server config. If you want a fast, private, no-nonsense check of whether the AI engines that matter can actually reach your site, start here. If you need continuous monitoring across every known AI user-agent, step up to BrandCited. For the wider picture of getting cited once the bots are in, see our best AI bot checkers roundup.
