Glyfen is an offline-first OCR app for Android that lets you search your photo library by text content. All processing happens entirely on your device — no cloud uploads, no internet required. Point Glyfen at your photo folders and it scans every image for text using PaddleOCR. Receipts, documents, screenshots, business cards, labels — if an image contains printed text, Glyfen extracts it and makes it searchable. A note on speed: because all OCR runs on your device, scanning takes time — and you always start it yourself. Glyfen never scans automatically or on a schedule. How long a scan takes depends on how many images it covers and your phone's hardware, so a large library on an older phone can take a while. Once you start a scan it keeps running even while you use other apps, and it resumes automatically if it's interrupted. Added new photos? Just run a scan again to index them. Once scanned, your photos become searchable. Type a word and Glyfen lists every image whose text contains it, with a preview of the recognized text. Full-text search is powered by SQLite FTS5 for fast results even across thousands of indexed images. Key features: - Offline OCR: All text recognition runs on-device using PaddleOCR. No network connection, ever. - Full-text search: Find any receipt, note, or screenshot by the words inside it, in seconds, powered by SQLite FTS5. - Latin-script first: Recognition and dictionary correction are tuned for English and Latin scripts. The underlying PP-OCRv5 model also recognizes Chinese, Japanese, Korean, Cyrillic, Arabic, and more. - Batch scanning: You pick the folders and start the scan yourself; Glyfen then processes them on-device and keeps running while you use other apps. Speed scales with how many images you scan and your phone's hardware. - Private by design: No analytics SDKs, no ads, no accounts, no tracking. Nothing is ever sent automatically. Optional diagnostics and telemetry are off by default and only leave your device if you cho
