ai bot log analyzer
Free AI Bot Log Analyzer
Upload or paste your server access log and see exactly which AI crawlers visit your site — GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot and 20+ more — what pages they fetch, whether they hit errors, and how many human visitors arrived from ChatGPT, Perplexity, and other assistants. Runs entirely in your browser: your logs are never uploaded.
Built for ai bot log analyzer
Your access log already knows which AI engines read your site
Every request to your server leaves a line in the access log, including the ones from AI crawlers. Paste those lines (Nginx or Apache combined format, or JSON lines) and this tool classifies every known AI and search crawler by operator and purpose: answer engines fetching pages to cite, on-demand user fetches, search and ads indexers, and training crawlers.
It also reads the referrer column the other way: human visitors who clicked through from ChatGPT, Perplexity, Gemini, Claude, Copilot and other assistants show up as AI-referred visits with their landing pages. Analysis runs locally in your browser — no upload, no signup, no size anxiety about sending logs to a third party.
Common use cases
- Verify whether GPTBot, ClaudeBot, and PerplexityBot actually reach your origin
- Spot crawlers being served 4xx/5xx errors before it costs you citations
- Count real click-throughs from ChatGPT and Perplexity without GA4 access
Why your access log beats any tracking script here
AI crawlers do not run JavaScript, so they are invisible to Google Analytics and every tag-based tracker. The only place their visits exist is your server’s access log: one line per request, with the user-agent string the crawler sent. That makes the log the ground truth for questions like “does GPTBot ever reach my site?” and “is my firewall silently blocking Perplexity?” — questions no analytics dashboard can answer.
This analyzer reads two signals from the same lines. The user-agent column reveals machine visits: answer engines fetching pages to cite, assistants opening a page because a user asked, indexers building AI search and ads indexes, and training crawlers collecting data. The referrer column reveals the opposite direction: humans who clicked your link inside ChatGPT, Perplexity, Gemini, Claude, or another assistant and landed on your site.
How to read the results
Start with the behavior split. Answer-engine and user-fetch traffic is your citation surface — these bots fetch a page because an AI system is considering showing it to a person right now. If they are absent, the engines either cannot reach you or have no reason to visit. Indexer traffic (OAI-SearchBot, Bingbot, OAI-AdsBot) feeds the indexes AI search runs on. Training crawlers (GPTBot, ClaudeBot, CCBot) are a policy choice: blocking them does not affect whether you get cited today, and this tool shows you how much of your crawl budget they consume.
Then look at the 4xx/5xx column. A crawler that consistently receives 403s is being blocked by your CDN or firewall — the engine behind it sees nothing, cites nothing. A crawler that got 5xxs visited during an outage and now has a broken snapshot of those pages. Both are fixable, and both are invisible unless you look at the log from the bot’s side.
What this tool does not claim
A user-agent is a claim, not an identity — scrapers impersonate well-known bots, so counts here are claimed identities until you verify the source IPs against the operator’s published ranges or your CDN’s verified-bot flag. AI-referred visits are a lower bound, because many assistants strip the referrer. And being crawled is not being cited: a bot reading your page is necessary but not sufficient for the engine to ever mention you.
How to Use the AI Bot Log Analyzer
- 1Export or copy a slice of your access log (one day is plenty; up to 50 MB works)
- 2Upload the file or paste the lines — nothing leaves your browser
- 3Read the crawler table: hits, error responses, top pages, and last-seen per bot
- 4Check the behavior split: answer engines and user fetches are your citation surface; training crawlers are a policy decision
- 5Review AI-referred human visits to see which assistants already send you traffic
- 6Remember the evidence note: user-agents are claims — verify suspicious traffic by IP before acting on it
