## OCR - Image Reader

OCR - Image Reader is a Chrome extension from developer brian.girko that adds a toolbar button for on-the-fly optical character recognition. Press the button, drag a selection over any region of the active window, and the extension reads the text inside it using a Tesseract-based engine that supports over 100 languages with automatic orientation and script detection. A second engine option, IBM Granite-Docling, goes further and preserves headings, lists, bold and italic styles, tables and even mathematical equations instead of returning flat text. Everything runs offline in the browser, with no server round trips apart from a one-time download of the language training data.

**價格與方案:** Free. The Chrome Web Store listing is free with no in-extension subscription or credit system.

- **Region-select OCR:** Click the toolbar icon, draw a rectangle over any part of the active window, and the text inside is recognised immediately.
- **100+ language engine:** A Tesseract.js engine recognises plain text in over 100 languages with automatic text orientation and script detection.
- **Layout-aware Granite-Docling engine:** Switch to IBM Granite-Docling to retain headings, lists, bold and italics, tables and mathematical equations instead of losing layout.
- **Private offline processing:** The OCR runs entirely in the browser with no server calls; only the language database is downloaded once and then cached.
- **Automatic retry logic:** If confidence is low the extension inverts the image and retries, and you can drop a modified image back in to try again.

**優勢:** Completely offline OCR, which suits confidential documents; Over 100 languages handled automatically with script detection; Granite-Docling engine preserves tables, headings and formulas; Tiny resource footprint because the JS library is loaded and removed per session

**限制:** Local OCR speeds depend heavily on your CPU, especially on the first run; Tesseract engine returns plain text only and does not keep tables, headings or formatting; No built-in translation or cloud sync; the output lives in your clipboard; Accuracy drops on noisy scans or unusual fonts without a retry

## OCR Text Recognition

OCR Text Recognition is a lightweight Chrome extension that turns images and screenshots into selectable text via the right-click menu. Right-click any image on a page and choose 'Recognize image text' to pull the words out; right-click anywhere else and choose 'Screenshot Recognition Text' to select a screen region and read it. There is no account, no dashboard and no clutter — it is a single-purpose browser utility for grabbing text you cannot select.

**價格與方案:** Free. The Chrome Web Store listing carries no price, subscription or credit system.

- **Right-click image OCR:** Right-click any image on a web page and the extension identifies the text inside it without saving or opening the file separately.
- **Screenshot region recognition:** Right-click anywhere else on the page to launch a custom screenshot region selector and recognise text from that area.
- **Context-menu workflow:** The extension operates from the browser context menu, so it does not take up toolbar space or require a pop-up window.
- **Image text to clipboard:** Uses an OCR engine to convert picture-based characters into copyable text for reuse in documents or search.
- **No sign-up required:** All processing is initiated from the page itself with no separate app, upload form or account required.

**優勢:** Extremely simple: two right-click modes and nothing else to learn; No download-then-upload cycle; recognition happens in place; Works on images, charts and locked web pages via screenshot mode; Free with no account or paywall

**限制:** Only 2 interface languages (English and Simplified Chinese); Rating average is modest at 2.9 from 14 ratings; Works from a context menu only — no floating toolbar or batch mode; Full-page text recognition is limited to custom screenshot regions
