Smart document tools

Extraction, checking and question-answering for when converting a file is not enough.

Whiteout covers something on the page with a clean box — a scan artefact, an old stamp, a stray mark. It is the digital version of correction fluid, and it is deliberately not the same thing as redaction.

🔒 Never used for AI training: delete a document and it is gone from the server.
⚡ No watermarks: on any tool, including the free tier.
↩ Undo: step back through your last 10 edits.

Questions people ask

Does whiteout remove the text underneath?

No, and this is important. Whiteout covers text visually — the text is still in the file and can still be copied or extracted. To remove sensitive information for real, use Redact, which deletes the text itself.

When should I use whiteout instead of redact?

Use whiteout for tidying: scan edges, stamps, marks, things that are untidy rather than private. Use redact for anything you would not want a stranger to read.

Can I whiteout several areas at once?

Yes. Draw as many boxes as you need across as many pages as you need.
