Does the camera feed get uploaded anywhere?

No. The camera stream is accessed with the browser's WebRTC API and stays local to your device; the captured still frame is processed in-browser too.

Will it automatically detect the edges of my document?

The current version captures the frame as-is; automatic edge detection and perspective correction are on the roadmap.

Yes, if your device has a camera and your browser supports the getUserMedia API, which includes all current major browsers.

Use your device camera to capture a document and save it as a PDF or image — no app install required.
