Overview

Product summary

Review the store description, core capabilities, and common use cases.

This extension adds a toolbar button to your browser to perform OCR. When this action button is pressed, it allows the user to select a region in the currently active window. The extension captures the area and tries to recognize text inside this region using the internal powerful OCR engine (Tesseract engine). This extension uses the "tesseract.js" library that supports more than 100 languages, automatic text orientation, and script detection.

This extension loads the JS library on the page and removes it when you are done. This way, there is no long-term resource usage.

Engines:

Tesseract: Only extracts plain text from images and doesn't preserve formatting

IBM Granite-Docling: it can accurately interpret headings, lists, styles (bold, italics), tables, and mathematical equations.

Doens't work at all. Never gets even simple text right and results are all inconsistent.

Damien L2022年6月7日

This saved me so much time copying from unselectable PDFs

It doesnt even work with constant error messages about permissions or whatnot, not a single clue on the website as to what it could be

Llega a fallar

Peter Bahout2022年5月28日

it's completely free and can detect for example the letter G even if half of it is covered by a cursor. I got this because blackbox which is a similar and way worst extension started making people pay 30$ a month even though its already very inaccurate.

works. Would love to see better UI

Funciona bem, pode melhorar um pouco

I want to copy a code from youtube video and it didn't work

Sometimes never runs. When it does run, it glitches out and half of it is just random letters.

Offline optical character recognition (OCR) that captures a user-selected region of any webpage and converts the image content to text

Users need to extract text from images, screenshots, or scanned content visible in their browser without manually typing it out. This solves the problem of converting visual text (in images, PDFs rendered as images, etc.) into selectable/editable digital text.

1. User clicks the extension toolbar button on any webpage. 2. A crosshair overlay appears for region selection. 3. User drags to select the area containing text. 4. Extension captures the visible tab as a screenshot, crops the selected region. 5. OCR engine (Tesseract or Granite-Docling based on accuracy setting) processes the cropped image offline. 6. A floating result panel appears showing extracted text with copy/export options. 7. For internal pages that can't be directly captured, the extension opens a cloned tab with the screenshot for region selection.

Target users: Researchers and students extracting text from academic papers or screenshots / Developers copying code or text from images/videos / Translators working with text in images in foreign languages / General users who need to quickly extract text from any visible webpage content / Accessibility users who need text from image-based content

The extension bundles large third-party libraries (Tesseract WASM ~4MB, transformers.js ONNX ~21MB WASM, KaTeX ~610KB) which are well-known open-source projects - no suspicious code injection detected
The 127.0.0.1:8080 references in elements.js appear to be example/test URLs in a demo, not a live backend
No privacy policy URL provided in the store listing

Monetization

No paid features detected

No payment infrastructure, premium tier, subscription model, or feature gating found anywhere in the extension source. All OCR engines (Tesseract and IBM Granite-Docling via ONNX) are fully accessible without any paywall. All 'pro' keyword hits are false positives (proceed, progress, Promise, provide, protocol, process, etc.). No Stripe, PayPal, or any payment platform integration detected. No premium/upgrade/purchase/buy keywords found.

Confidence: 97
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates entirely offline with no authentication system, account creation, or login UI. No login/signup keywords found in source code. The extension performs OCR locally using Tesseract.js and ONNX Runtime (transformers.js) without requiring any user account or server-side authentication. All 'token' hits are from KaTeX parser library (linguistic tokens, not auth tokens) and 'account' hits are about 'accounting for' differences, not user accounts.
