Key features: · Offline by design: No uploads, no tracking, no ads. · Precise crop first: Drag corners or edges to target exactly what you need. · Multi-language OCR: Recognize text across many languages; auto-detect supported. · Proofread with highlights: See bounding boxes over the original image to verify accuracy. · Editable results: Review recognized text in a clean editor and copy with one tap. · History on-device: Keep up to 100 entries locally; view, edit, or delete anytime. · Camera and gallery: Snap a photo or import from your library; optional save-back after cropping. · Share and export: Copy lines or full results; share with friends. · Privacy-first: No analytics, no remote processing—everything runs locally. How it works: 1. Choose Photo or Camera, then draw the crop box. 2. OffLens runs VisionKit OCR offline and overlays highlights for quick review. 3. Edit text if needed, then copy or share.
