Offline screen region capture and optical character recognition grabber
Offline Screen Region OCR is an independent open-source Linux alternative to Capture2Text and Text Grab for instant offline screen-region text extraction and clipboard capture. It is not affiliated with, sponsored by, or endorsed by the authors of Capture2Text or Text Grab.
FEATURES
- Translucent Crosshair Region Snipper: Capture any screen rectangle across single or multi-monitor X11 desktops using a fullscreen rubber-band overlay or global X11 hotkey (Ctrl+Alt+T), or load PNG/JPG files and clipboard images.
- Image Preprocessing Pipeline: Automatic 1x/2x/3x smooth upscaling for crisp small UI fonts, grayscale contrast normalization, optional dark-background auto-inversion, Otsu adaptive thresholding, and quiet border padding.
- Bundled Offline Tesseract 4 OCR Engine: Zero cloud uploads — ships complete offline English (eng) and Vietnamese (vie) language models with selectable page segmentation modes (Auto, Single Block, Single Line, Sparse Text).
- Instant Clipboard & Live Confidence Metrics: Copies recognized text directly to the system clipboard alongside word count, character count, and mean Tesseract per-word confidence score.
- SQLite OCR History & Export: Browse searchable capture history with saved region thumbnails, re-copy past extractions, and export to TXT, Markdown, or UTF-8 CSV files.
