Free AI visibility tools

Every check here reads a public file on your site and shows you the whole result, including everything that failed. No signup, nothing blurred, nothing held back for an upgrade.

• Is GPTBot blocked on your site?Tests the GPTBot user-agent specifically, which builds the index the model answers from.
• Is ClaudeBot blocked on your site?Tests the ClaudeBot user-agent specifically, which builds the index the model answers from.
• Is Google-Extended blocked on your site?Tests the Google-Extended user-agent specifically, which collects pages used to train the model.
• Is your llms.txt valid?Reads and parses the llms.txt file itself, rather than testing a crawler rule.

The bigger checks

Same deal: free, no signup, full result.

• Full AI crawler checkEvery AI crawler at once, including the retired ones you may still be blocking.
• Free AI visibility auditThe whole picture: crawler access, readability, schema, and a scored action plan.

Why these are free. Each one fetches a public file and reads it, so it costs us nothing to run and can stay free permanently. What we sell is the part a one-off check cannot do: running it on a schedule, keeping the history, and telling you when something changed.
