Fake blur isn’t redaction. Permanent blackout is.
Sharing a screenshot with an email, API key, or face still visible is a liability. Soft blur can often be undone. BlotOut draws solid black that exports burned in — offline, in your browser.

Permanent screenshot blackout. No upload.
The problem
People paste secrets into Slack, docs, and support tickets every day. Cloud “redact” tools ask you to upload the same sensitive image you were trying to protect. Blur looks safe until someone reconstructs it.
What BlotOut does
- Draw solid black blots over emails, names, keys, and faces
- Export burns the redaction into the image (not a reversible overlay)
- Optional auto-detect hints to speed up common PII patterns
- Client-side / offline-capable — nothing uploads
- $2.99 lifetime unlock
Who it’s for
Support teams, engineers sharing logs UI, freelancers documenting client work, and anyone posting screenshots publicly.
Vs blur — why screenshot blur/pixelate isn’t permanent redaction.
