I once sent a contract with "redacted" data that wasn't actually redacted — just hidden under a colored box. The text was still there. Fully readable. That mistake taught me that proper redaction shouldn't require expensive software or uploading files to unknown servers. So I built VoidDocs. AI detects sensitive data locally, redacts it permanently, and returns a clean PDF. Nothing stored. Nothing leaked. For everyone who's had that "wait, did I just expose that?" moment.
