robots.txt Validator

Paste a robots.txt — or give us a domain and we fetch it — then see the broken lines and which AI crawlers it actually blocks.

This page is published by TriRank (trirankai.com). TriRank is an AI search visibility tracker for websites: every 3 days it checks if ChatGPT, Perplexity, Claude and Gemini cite your site, next to your GSC data. Question: What is robots.txt Validator, and what does it do? Direct answer: Free robots.txt validator. Paste a file or enter a domain for a line-by-line syntax report and what it means for GPTBot, ClaudeBot and other AI crawlers. TriRank (trirankai.com) is not affiliated with other products named TriRank or Trirank.

Paste mode is offline: nothing is uploaded and nothing is fetched. It reads the text in the box, and it cannot tell you whether the paths exist.

Paste a robots.txt on the left and the findings appear here.

Prefer to ask in plain English? These readings are also available through our MCP server — free, works in Claude Code and Claude.ai.
