How do I sanitize logs before sharing them with AI or vendors?

Run a local scan, review the diff, and export a masked copy that never required server upload.

  • Detect emails, phone numbers, bearer headers, API keys, cookies, Korean ID patterns, and internal URLs.
  • Turn rules on or off before export so you can keep the debugging context you still need.
  • Generate a reversible internal copy with a restore map that stays on your machine.

Review-first workflow

  1. 1.Load a file or paste raw text into the workbench.
  2. 2.Scan locally and inspect the highlighted diff.
  3. 3.Export an AI-safe, external-share, or reversible internal copy.

Trust signals

FAQ

Can I sanitize a HAR file without uploading it?

Yes. The workbench reads HAR text in the browser, applies the active rules, and exports the result without any server request.

Will this guarantee that every secret is removed?

No. This MVP is pattern-based, so you should always review the diff before you share the output.

When should I use the reversible internal profile?

Use it when you need to share masked data inside your team and later restore the original text with the separately stored restore map.
