What's New in Kortext

June 4, 2026

Bug fixes and improvements.

User reviews

One can read, nothing more.

Translations are missing, zoom is not working, progress is not being saved, bookmarks not visible.

Itโ€™s messy

Digital text books are a pain in general. Largely because you canโ€™t flip through them like a regular book. But with Kortext specifically, I canโ€™t just highlight AND notate on the page that Iโ€™m reading. I have to create a notes page which is a pain to go back and reference later. It also takes time to load and I havenโ€™t been able to figure out how to just edit the notes page that Iโ€™ve already taken notes on. I have to create a new notes pagesโ€ฆ I miss regular text books.

difficulty

The app and website are super slow. I always have to refresh both because of how many times it freezes when I am imputing notes. Horrible system to get your books!!!!!!

What a freaking insult

I got this app so I can do my college work. It is OK for reading however I do a lot of driving so I thought maybe I would have the app read to me so thatโ€™s where the insult starts if you want Stephen Hawkins to read you and this app will be great. It literally sounds like a computer. You can barely understand not to mention the features in here are so ridiculously lockdown. Itโ€™s almost a worthless app.
