AI Bot Log Analyzer

Paste your access log and see which AI bots visit, what they fetch, and whether they're real. Your log never leaves your browser.

How it works

You paste log lines or choose a file. Your browser reads it on your device.
We send you the public IP lists that OpenAI, Anthropic, Google and the other bot operators publish. That's the only data our server sends, and it receives nothing from your log.
Your browser checks every bot request against those lists and shows the report. Close the tab and it's gone.

What we never do

We never upload your log, its lines or its IP addresses. There's no place on our server to send them to.

When you run an analysis, we record that the tool was used, as on our other free tools. Nothing from your log is part of that.

The CSV download is made in your browser too, and leaves out IP addresses.

How to read your report

From official network: the IP is in the company's published list, so it's a real bot.
Not in official list: someone used a bot's name from an IP outside the list. Often a fake, sometimes a gap in the list.
No IP list: the company publishes none (Meta, Amazon and Mistral, for example). Check with reverse DNS or their documentation.
Lots of 403 or 5xx answers? Then you're blocking or breaking AI access.

Frequently asked questions

Is my log uploaded?

No. Reading and matching happen in your browser, in a background worker. Our server only sends the public IP lists and never receives your log lines or IP addresses.

Which log formats work?

nginx and Apache “combined” logs and Cloudflare Logpush JSON lines. For other formats we still find bot names, but no pages or status codes. The “common” format has no user agent, so it can't show bots.

How big can my log be?

Up to 20 MB of log text; a .gz file counts after unpacking. Anything above 20 MB is cut off. On a phone, a few thousand lines is plenty.

Why is a bot “not in official list”?

The request used a bot's name, but its IP isn't in that company's published ranges. Usually someone faked the name. Lists can lag behind, so check a suspicious IP with reverse DNS before you block it.

How fresh are the IP lists?

Our server fetches them from the companies about once a day. The report shows each list's own date and when we fetched it.
