TextDet is an offline image-to-text OCR app for Android. Photograph a receipt, a page, a sign or a screenshot and the app reads it into editable text on the phone, with no internet connection, no ads, no account and no daily limit. Two on-device engines cover 37 languages: Google’s ML Kit reads Latin, Chinese, Japanese, Korean and Devanagari scripts, and PP-OCR handles the rest. Every scan is kept in a searchable on-device library with tags, and text can be edited, exported as TXT or Markdown, read aloud, or tapped to open web addresses, email addresses and phone numbers found in the text. The same PP-OCR engine also runs in the browser on textdet.com for quick desktop checks. TextDet Pro is a single $5.99 lifetime purchase that adds multi-page documents, PDF import, searchable PDF, Word and CSV export, receipt line items and translation between 59 languages. It suits students digitizing notes, travelers reading signs, and anyone who wants receipts and paperwork as searchable text without uploading images to a server.
