User Reviews

Review themes consistently show Kortext as a mixed bag: when it functions, users find it usable but fragile. The major pain points are navigation and page control (LOC instead of pages, hard jumping to chapters), frequent crashes and sign-in problems, and problematic Read Aloud features. Users also complain about limited annotation options and highlight behavior, plus access issues (duplicate accounts, login loops, and slow support). A few reviewers note the app is decent or not bad when working, but overall reliability and usability appear to be the core hurdles blocking effective use for coursework.

Pros

When it works, the app is usable and some reviewers call it decent/not bad.
Annotation features exist (highlighting and notes) and are usable to some extent.
For students using school-purchased ebooks, Kortext provides centralized access in a single app.

Cons

Frequent crashes, slow loading, and sign-in/out problems.
Poor navigation and paging: uses LOC instead of real page numbers; hard to jump to chapters and scrolling is inconsistent.
Read Aloud features are unreliable: limited voices, stops at page end, not continuous.
Annotation/highlighting limitations: can't cross pages, cumbersome UI, copying text is difficult.
Account/access issues: duplicate accounts, login loops, accounts not found, and slow or unresponsive support.

Recent reviews

App has fewer features than the mobile browser which is more easy to use. Pen still works there… and you can navigate by page number. Never thought I’d take something simple like c that for granted. Also, on the app, when you are making an “inking” 🐙.. the highlight or writing doesn’t stay on the text? Defeats the purpose to have to go searching for it.

The buttons barely work (especially the back button) and it doesn’t let you see the textbooks you downloaded on your computer. I’d use vitalsource or anything else if possible
