How RedactGuru works
Four steps from raw document to fully redacted file.
Upload
Drop in a document or image, from your device or a connected cloud drive.
AI Detects
RedactGuru scans every page and flags sensitive information automatically.
Review & Approve
Confirm or adjust flagged items with your team before finalizing.
Download
Export a permanently redacted file, safe to share anywhere.
Private by design
Detection that never leaves your machine
The RedactGuru engine runs entirely on your computer, so your documents are scanned without being uploaded anywhere — it even works with no internet connection.
Your call
Replace, mask, or black out
Swap sensitive details for realistic stand-ins, cover them with asterisks, or remove them behind a solid block — whatever fits where the document is going.
Pick the model that fits the job
Switch between offline detection models to balance speed and thoroughness.
- Use a lighter model for quick passes, a larger one for maximum coverage
- Every model runs on your device — nothing is sent to a server
Teach it what matters to you
Add your own rules for the details only your organization knows are sensitive.
- Flag client codes, project names, or internal IDs
- Rules apply automatically to every document you open

Frequently asked questions
