Sanitize logs before sending them to an AI

Raw log files are huge, repetitive and full of secrets. Cleaning them first means 80% fewer tokens and no leaked API keys. All processing happens in your browser.

Why send raw logs to an AI at all?

A typical error investigation pastes the whole log file into a chat. That is the worst version of the data you have:

• Retry loops repeat identical lines thousands of times — pure token waste.
• Timestamps and request IDs on every line double the size again.
• Authorization headers, tokens and emails sit in plain sight.

What "Clean for AI" does

• Collapses repeated runs — 3 copies kept, the rest replaced with a [repeated Nx] marker.
• Removes duplicates — identical lines (ignoring timestamps) appear once.
• Redacts secrets — Bearer tokens, API keys, passwords and emails become <REDACTED>.

The error lines, warnings and structure the AI actually needs stay intact.

Is my log uploaded anywhere?

No. This page is a single static HTML file — cleaning runs entirely in your browser. Disconnect from the internet after it loads and it keeps working.
