Difficult to navigate among pages. Terrible app ### 1/5 — Awful *2026-08-29, version 5.4.22* Clunky and awkward. Can’t scroll pages like in kindle. Have to tap the arrows. Doesn’t seem to save my place. If I accidentally close the app, I lose my place every time. It’s very stressful. I am using this app for a PhD course and I’m afraid I’m going to fall behind because I lose so much time fighting from this app. ### 2/5 — App struggles to save notes *2026-08-28, version 5.4.22* I’ll highlight text and attach a note to said highlights. However, whenever I reopen the app all of my notes are gone. The Highlighted text are still lit but then note associated with it are just gone. ### 3/5 — Lags a lot *2026-08-28, version 5.4.22* Started using Kortext for school and every time i try and use it I have to repeatedly close it out or shut it down since it won’t stop freezing or lagging ### 1/5 — Useless *2026-08-28, version 5.4.22* I had to buy an expensive textbook for a class, tried using the app to get full functions, and it has me going in circles to keep signing in. Can’t do anything on the app, without signing in to utilize the textbook. However, the app won’t sign you in. ### 2/5 — Bad read aloud *2026-08-28, version 5.4.22* I wish I could give this app a good rating because I really needed it to work well for school. I'm in online classes, a mother of two, and work full time. I needed a read aloud so I could listen on my 45 minute drive to work, because that's what work a best for me and my busy schedule. I was extremely disappointed when I heard the read aloud. They have a lot of “options” for read alouds, but they are all terrible AI voices. All of them. Not onesiundseven remotely close to a real humans voice. I can barely understand it and when it is reading aloud it make simple enunciation mistakes and punctuation mistakes. ### 1/5 — Kortext *2026-08-27, version 5.4.22* This app has a lot of bugs and is not efficient. ### 1/5 — Sign in *2026-08-27, version 5.4.22* I can’t even sing in it lets me use my email and password but then when I sign in it doesn’t work yall need to fix you app especially at this critical time with college ### 2/5 — Read Aloud Option *2026-08-26, version 5.4.22* Is the Read Aloud option supposed to be a joke? I have to use this site/app for a class and it is helpful to have the “read aloud” option available when life is busy. But if your app just does not have the capability to provide a decent option don’t make it available. There is a “bell” voice if you can call it a voice and the “good news” sounds like it is singing to you. I’m glad you all are having fun playing with the sounds over there but some people need real options to choose from. I only gave it two starts because I can read the material myself. Last semester, I re-purchased my book from another provider because the pages all merged together and the professor asked us to cite our work. ### 2/5 — Disappointed *2026-08-24, version 5.4.22* This app is Super glitchy, the READ BACK mode is really slow and robotic sounding, you can’t even change the speed you get to listen to it in. I can’t believe this company has a contract with universities. It’s like a bad joke honestly. Do better KORTEXT put the money you’ve received back into the app and truly develop this software, or give us customers a DRM FREE PDF so we don’t have to stay on this platform and suffer the whole semester trying to read our books. Right now it’s false advertisement to claim a READ ALOUD function with variety. ## Frequently asked questions about Kortext ### What is Kortext?
