Which AI crawlers actually read your site?
Upload your access log. See GPTBot, ClaudeBot, PerplexityBot and more — how often they came, what they fetched, and whether they were real. Free, no signup, nothing stored.
nginx/Apache combined format or JSON-lines · up to 50 MB · nothing is stored
Grab an nginx/Apache access log (combined format) or JSON-lines from your server, CDN, or host. Even a day or two is enough to see who's crawling.
It's parsed in your browser's request and analyzed on the fly. Up to 50 MB. We keep nothing — no upload is stored, no account is created.
A breakdown of every AI crawler that hit your site: how many requests, what they fetched, what they got back, and whether each hit was verified against the provider's published IPs (not a spoofer).
Which crawlers does it detect?+
Known AI answer/training crawlers — GPTBot, OAI-SearchBot and ChatGPT-User (OpenAI), ClaudeBot and Claude-SearchBot (Anthropic), PerplexityBot, Google-Extended, CCBot (Common Crawl) and more — matched by user-agent, then IP-verified where the provider publishes ranges.
Is anything stored?+
No. The log is streamed, classified, and aggregated in memory, and only the summary is returned to your browser. We don't keep the file, the raw rows, or any IP addresses. Reload the page and it's gone.
What log format do I need?+
Standard nginx/Apache “combined” access logs, or JSON-lines (one JSON object per line). Most servers, CDNs, and hosting dashboards can export one of these.
What does “verified” mean?+
For providers that publish their crawler IP ranges, we check each hit's source IP against them. A match means the request genuinely came from that provider — not a scraper spoofing the user-agent. Unverified isn't necessarily fake; some providers don't publish ranges yet.
How is this different from the paid product?+
This is a one-shot snapshot of a file you upload. The paid product builds recurring AI-answer visibility history from your exact prompts. Crawler-access changes can be watched separately from the crawler check.
