Description

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. Notes: 1. On the first run, the extension might take a few minutes to fetch the training data from the internet. Since this resource is cached, all subsequent calls are going to be fast. 2. Optical character recognition (OCR) is slow, so this extension displays a progress bar for each detection module. 3. This extension does the OCR process offline. There is no server-side interaction. It only fetches the language training database once. 4. This tool can be used to extract the text content out of images, PDF documents, Powerpoint slides, or extract the content of a web page when user-section is forbidden. 5. If the text extraction confidence is low, the extension inverts the image and retries (particularly useful on the dark theme) 6. If the text extraction is not accurate, you can modify the image and drop it into the interface to retry. Change Logs: Version 0.2.4: Supports browser-level page zooming and OS-level screen zooming Adds image language detection (still beta) (slow operation)

not good at all. Doesn't work with the text and will keep on fetching and recognizing and at the end, literally nothing.

As the previous reviewer has said, it is not working. Clicking the icon and there is no response from the extension.

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

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

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

The first run never completed, It just sat there not doing anything for over half an hour.

Does not work at all. No matter what text or numbers and language I choose - getting only "loading language traineddata" message and nothing actually loads.

It's very bad to detect english

Terrible OCR, the character recognition is horrific and if your text is even slightly angled, it just doesn't work.

★☆☆☆☆2021-09-21

Did not work at all. The error message said that there were "missing Host Permissions". After a lot of digging, I discovered indications that this *might* refer to a file called MANIFEST,JSON , but the developer's website gives no clue as to what the missing code should be. I'd love to get this going, but at present it's useless.

It's not working on youtube, it shows a SecurityError about executing "open" on "CacheStorage" and something about breaking the security policy of the user agent

No documentation. Not sure how to even run it. Clicking the Chrome extension button doesn't do anything. Nothing on the web site to tell you how to initiate a read. Might be a great app, but lack of instruction makes it useless for me.

It has more misses than hits... (tried to OCR Simplified Chinese characters)

Couldn't get it to work, it was just stuck on "loading language traineddata" Maybe its because Im on Brave or something?

Detection for Japanese was very bad and the extension was not able to load the language model in Brave.

It can be kinda slow sometimes, and it can be slightly inaccurate occasionally, so you just have to double check it (by inaccurate I mean it may think an I is a J when using a weird font) but otherwise it works fine.

It errors: SecurityError: Failed to execute 'open' on 'CacheStorage': An attempt was made to break through the security policy of the user agent. errorHandler @ chrome-extension://bhbhjjkcoghibhibegcmbomkbakkpdbo/data/engine/index.js:23 (anonymous) @ chrome-extension://bhbhjjkcoghibhibegcmbomkbakkpdbo/data/engine/tesseract/tesseract.min.js:2 t.onmessage @ chrome-extension://bhbhjjkcoghibhibegcmbomkbakkpdbo/data/engine/tesseract/tesseract.min.js:2

Acceptable, but it's prone to some corruption like most OCR programs are. It's not as good as the apple gallery OCR, but pretty good

I tried it on some German text and it did a pretty good job, but it put the letter c instead of e in dozens of words and had trouble with special characters: specifically umlauts (ü, ä) and ß. Fix those issues and it'll be a five-star product.
