Google DriveWhat they did
Reddit user u/Free_Fisherman3697 had a few old Bengali books as scanned PDFs, each over 300 pages, with blurry scans, broken fonts and many complex conjunct characters. They gave them to Gemini 4 Argon in Task Mode on a Pro student plan and asked it to turn them into proper digital books. Gemini read the scans, recreated the text with close to the original typography, pagination, margins and page layout, produced both PDF and EPUB versions, and uploaded the files to the poster's Google Drive.
How it went
The whole job ran in Task Mode without the poster stepping in. They read one of the rebuilt books and say they found no noticeable mistakes. A commenter reported Task Mode also built an 80-page, nearly print-ready PDF of exam tasks for them with little quota used.
Worth knowing
The accuracy claim rests on the poster reading one book, not a page-by-page check against the scans. Task Mode is a separate mode from regular Gemini chat, and commenters say it behaves very differently. No timings were given.
