Project Naptha automatically applies state-of-the-art computer vision algorithms on every image you see while browsing the web. The result is a seamless and intuitive experience, where you can highlight as well as copy and paste and even edit and translate the text formerly trapped within an image.

Words on the web exist in two forms: there’s the text of articles, emails, tweets, chats and blogs— which can be copied, searched, translated, edited and selected— and then there’s the text which is shackled to images, found in comics, document scans, photographs, posters, charts, diagrams, screenshots and memes. Interaction with this second type of text has always been a second class experience, the only way to search or copy a sentence from an image would be to do as the ancient monks did, manually transcribing regions of interest.

You can watch as moving your cursor over a block of words changes it into the little I-beam. You can drag over a few lines and watch as a semitransparent blue box highlights the text, helping you keep track of where you are and what you’re reading. Hit Ctrl+C to copy the text, where you can paste it into a search bar, a Word document, an email or a chat window. Right-click and you can erase the words from an image, edit the words, or even translate it into a different language.

Security & Privacy: Project Naptha handles OCR and text detection locally on your computer. When highlighting text, the extension checks a remote server to determine whether a public high quality transcription exists using a cryptographic hash of the URL (this includes no cookies, user tokens, or any identifying information, and the server is incapable of storing access logs). For more information, read the section on security and privacy on http://projectnaptha.com/

good concept, but not very practical in its current form. Often a site already grabs left/right click handlers on an image (eg processing code snippet images in Kindle Web Reader will not work - which was my main motivation for trying this extension in the first place). I strongly recommend adding a rectangular area select function like in screen capture tools, which can be started from the Naptha toolbar icon in a way that sites cannot override.

Novateur et utile, mais ne fonctionne pas pour autant. À chaque requête une erreur de connexion "No OCR servers available". Dommage, le service ne semble pas opérationnel.

Does not work on all images. Requires some minimum height at least. Also the default OCR isn't perfect even on very clear text and the other OCR complains about missing servers. Very little info available too about troubleshooting. Nice idea though.

Doesn't work on English: Tesseract, Japanese, or basically anything but the default language. Error: No OCR servers available
