Feature
Hide what you should not share, then ask
Cover emails, phone numbers, card numbers and keys in the capture itself. Redacted areas are removed from the image before it leaves your computer.
How it works
Blur and Pixelate work on the capture and in the editor; Auto-redact is in the editor.
- Capture Press Ctrl Shift 1 and select the region you want to ask about.
- Cover by hand Press Alt A to annotate on the capture. Choose Blur ( B ) or Pixelate ( X ) and drag over what must not be shared.
- Or let auto-redact find it Open the editor with Alt E and press Auto-redact in the top bar. SnapPrompt covers email addresses, phone numbers, card numbers, API keys and tokens, and says how many it hid.
- Send Blurred and pixelated areas are removed from the image before it leaves the app. Auto-redact can be undone with Show it again or one Ctrl Z .
Know the limits
- Auto-redact works on the text SnapPrompt recognizes, so text it cannot read is not found.
- It only looks for emails, phone numbers, card numbers, API keys and tokens. Names, faces and addresses need Blur or Pixelate.
- Always look at the final image before pressing Send.
If your organization wants fixed limits on what can leave the app, an organization policy can set image retention and lock settings.
What else the editor does
The editor has Box, Ellipse, Arrow, Line, Pen, Highlighter, Text, numbered Steps and Crop next to the redaction tools, with undo and redo. Your edits are kept with the capture, so you can return to them from History. The optional Background (Beautify) is added only when you copy or save the image, never to the image sent to Claude.
Frequently asked questions
What does auto-redact find?
It looks for email addresses, phone numbers, card numbers, API keys and tokens in the text SnapPrompt recognized in your capture, and covers them. A notice under the image says how many were hidden.
Can I undo auto-redact?
Yes. The notice has a Show it again action, and one Ctrl+Z also undoes all the redactions it made.
Is a blurred area really removed from the image Claude receives?
Yes. Blurred and pixelated areas are removed from the image before it leaves the app, so the hidden pixels are not sent.
Does auto-redact catch everything?
No. It depends on text recognition and only looks for the kinds of data listed above, so check the image before you send it and cover anything else yourself with Blur or Pixelate.
Do hidden areas stay hidden when I reopen a capture from History?
Yes. Edit and resend opens the image in the editor so you can change it and send it again, and hidden areas stay hidden.
