Project Naptha
Project Naptha lets users highlight, copy, and translate text found in images through computer-vision processing.
About Project Naptha
Project Naptha is a browser extension that applies computer-vision processing to images on web pages. It lets users highlight, copy, edit, and translate text that appears inside images, such as comics, document scans, photographs, charts, and diagrams. The homepage offers an "Add to Chrome" button and asks whether the visitor uses another browser.
Text recognition is less reliable for some image types. The source states that copying text from comics often produces jumbled results because letters that touch are hard to separate. For photographs, the source says recognition is unpredictable and advises users to set expectations low. Text rotated by more than about 30 degrees is not handled well.

Project Naptha FAQ
Can I use Project Naptha on image files saved on my computer?
The source says you can drag an image file into the browser window. It notes that you may need to open chrome://extensions and enable the "Allow access to file URLs" checkbox.
Does it work on rotated or vertical text?
It supports rotated text, but the source says recognition fails when text is rotated by more than about 30 degrees. Vertical text is not supported.
Why does copied text from comics sometimes come out jumbled?
Handwriting and lettering in comics are difficult to process because characters are often close together or connected, which makes it hard to separate individual letters.
