Will it find tokens or API keys in code screenshots?

It will find them as text, but the regex doesn't have a specific 'API key' pattern (they're too varied). You'll see the words highlighted by the document/PII step and can mark them. We're considering a 'detect long alphanumeric strings' pass.

Can I just cover the whole screen with one region?

Yes — the simplest move is to drop the image and drag a region over the entire display. Two clicks, no thinking.

Does it remove Slack-style hover tooltips and avatars?

Those are part of the image you uploaded. Anything visible in your screenshot is fair game for blurring — the editor lets you draw a region anywhere.

Is my screenshot used to train any AI model?

No. AWS Rekognition and Google Cloud Vision both prohibit training on customer data per their service terms. We don't run any in-house model.

I only need one name hidden, not the whole screenshot.

Then the lighter page is Blur text in an image — drag one rectangle over the name and export. This page is for captures where lots of regions matter.

Does exporting recompress my screenshot?

The export re-encodes the image (that's what makes the blur permanent and strips metadata). For UI captures, PNG keeps text crisp; JPEG is fine for photographic content.

How it works for screens.

Drop the screenshot
Anything: code editor, Slack thread, dashboard, mobile app screen, terminal output. Up to 20 MB.
Sensitive bits get outlined
We detect the screen region, OCR the text inside, and flag PII patterns. Outlined regions appear over the canvas — toggle or extend as needed.
One blur for the whole screen, or surgical strikes
Cover the whole screen with one big region, or layer many small ones over emails, names, prices, account numbers. Export with EXIF stripped.
