Description
Sharing a medical report or contract with an AI assistant means either manually blacking out your name and account numbers with a photo editor, or just uploading it as-is and hoping for the best. BlankOut handles the blacking-out step in one tap, entirely on your phone, so nothing sensitive ever touches a server before you decide to share it.
BlankOut is an Android app that detects and redacts personally identifiable information from documents using fully offline, on-device AI, also stripping GPS and EXIF metadata from photos. It's early-stage (about 3 months old at Product Hunt launch, #39 daily rank), with a free tier of 5 redactions/day and a one-time purchase for unlimited use.
💬 Our review
The short version: BlankOut solves a real, specific problem — redacting PII before you paste a document into an AI chat — and doing it fully offline is a genuine trust advantage, but it's Android-only and very early-stage.
There's no direct competitor doing exactly this on-device redaction-for-AI-sharing niche; broader privacy tools like Signal or Privacy Badger solve adjacent but different problems (secure messaging, anti-tracking). BlankOut is worth a try if you regularly share sensitive documents with AI tools on Android, but the 5-redactions-a-day free cap and lack of an iOS version limit how far it goes right now.
