Local analysis, no log upload
Logs can contain personal data. This page does not send or save them. It supports only documented log formats; unrecognized lines are flagged, and heuristic results are not bot-detection conclusions.
AI Bot Log Analyzer & Bot Checker
Analyze server access logs locally to find GPTBot, ClaudeBot, PerplexityBot, requested URLs, IPs, and status codes—no log upload.
No upload
Paste or choose an access log to find known AI crawler markers such as GPTBot, ClaudeBot, and PerplexityBot, then compare requested URLs, IPs, and HTTP status codes including 200, 403, and 429. Analysis stays in this browser; markers are investigation signals, not proof of identity or intent.

Understanding bot checker results
How does log analysis for bot detection work?
This tool parses supported server access-log lines in the current browser and compares User-Agent text with known AI crawler markers.
What does this bot checker report?
Results show matching markers, requested paths, IP addresses, and status codes so you can review crawl locations and server responses.
Can a User-Agent marker prove bot identity?
No. Log markers are investigation signals and cannot confirm who controlled a client or prove a requester's identity or intent.
