Smart document tools

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

Avoid accidental data breaches before sharing or publishing PDFs publicly. Doclium scans your document for exposed Social Security numbers, credit card numbers, email addresses, phone numbers, confidential watermarks, and hidden author metadata.

🔒 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
