## 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.

**Preços e planos:** 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.

**Pontos fortes:** 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

**Limitações:** 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

## TF Image Classifier

TF Image Classifier is a free Chrome extension that runs TensorFlow.js MobileNet v2 and COCO-SSD models locally in your browser to label images and detect objects on any website.

**Preços e planos:** Free. No subscription, account, or in-app purchase is required to install and use the extension.

- **MobileNet v2 classification:** Labels images across more than 1,000 categories using the TensorFlow.js MobileNet v2 model, giving a broad read on what an image most likely depicts.
- **COCO-SSD object detection:** Detects and localizes around 80 common object classes with bounding boxes, useful for spotting people, animals, vehicles, and household items in a photo.
- **Runs fully in-browser:** Inference happens locally in the Chrome tab through TensorFlow.js, so no image is uploaded to a remote server and no account is needed.
- **Works on any site:** Point it at images on virtually any web page; the developer recommends pairing it with a CORS unblocking extension for images served from other domains.
- **Educational and free:** Built primarily as a hands-on way to explore pre-trained computer-vision models, offered at no cost by an independent developer.

**Pontos fortes:** Completely free with no account, login, or subscription required; Runs locally in the browser, so images are not uploaded to a third-party server; Covers both classification (MobileNet) and object detection (COCO-SSD) in one small extension; Lightweight install and simple, focused interface for quick experiments

**Limitações:** Accuracy is limited to the bundled pre-trained models and can be wrong on unusual or niche images; Some sites need a separate CORS-unblocking extension before images can be read; Modest user base and a single maintainer, with infrequent update history
