Receipt Scanner

Privacy-first OCR that processes documents entirely in the browser.

Problem
Document scanning services require uploading the document, which is unacceptable for anything sensitive.
Approach
OCR and image processing run locally in the browser, with no server round trip and no backend requirement.
Result
Receipts, business cards, and whiteboards are digitized without the image leaving the device.
