Common questions

Bengali or Arabic pages come out as gibberish or Latin letters

The language pack for that script is not installed yet. Go to Settings → Languages and download it. The pack is 11 to 14 MB and downloads once; after that recognition works offline. If a scan hits a missing pack the app also offers the download right there.

The download keeps failing

Check that you are online and have at least 30 MB free. Packs come over HTTPS from GitHub; if GitHub is slow on your network, try Wi-Fi or a different connection. An interrupted download is discarded and can simply be retried.

Recognition is poor

Fill the frame with the page, keep the phone parallel to it, and avoid shadows across the text. The camera waits until the image is steady and sharp before capturing. The Document scanner option finds the page edges and flattens it, which usually gives the best result for photographs of books. Account holders can also switch on High-accuracy reading for difficult pages.

Live text is slow on Bengali

Bengali is read by Tesseract, which takes about a second per frame on a mid-range phone. Hold the phone still; the app only reads when the image is steady. English and Hindi are much faster.

Read aloud says the language is not available

Your phone's text-to-speech engine has no voice for that language. Open Android Settings → System → Languages → Text-to-speech output and install the voice. Bengali voices are missing on many phones by default.

Exported PDF shows Bengali oddly in the text layer

The visible layer of a searchable PDF is the page image, so what you see is correct. The invisible text layer is there for search and copy. For a visible, reflowable text document use the HTML export, which renders every script correctly.

I have reached the daily export limit

Guests can export five files a day. A free account removes the limit. Your existing scans come with you when you sign up.

Will I lose my scans if I uninstall?

As a Guest, yes. Your library exists only on the phone. Create a free account and use Back up now before uninstalling or changing phones.

How do I delete my account?
