For every 10 questions; only 7 came back as a correct response as if someone were controlling it... ## Most critical reviews (10 lowest-rated) ### 1/5 — Useless app, dont buy *2026-01-15* Don't buy, no updates since 2 years ### 1/5 — My file isn’t uploading into the app *2025-08-10* I didn’t even get to try the app cuz it wouldn’t even accept my file into the system. Overall a waste of time. ### 1/5 — Fraud *2024-08-13* DO NOT DOWNLOAD, ITS VIRUS !!Please do not download this app , starts cutting 5 dollars monthly without even a subscription and there is no way to cancel subscription. ### 1/5 — App doesn’t work *2024-05-09* Doesn’t upload any files ### 1/5 — Dommage *2024-02-29* Pas de français ### 1/5 — Limited to 2million characters *2023-07-31* This chat bot is limited to 2million characters. I need to upload a operating manual that has 1875 pages to it. The chat bot cannot open the file. This limitation hinders the app. ### 1/5 — Doesn't allow copying text *2023-06-22* Not sure how anyone uses this if they cant copy the text it provides ### 1/5 — inaccurate & frustrating *2023-04-22* Several attempts to get full summaries. It just picks & chooses random things & comes to an erroneous conclusion. ### 1/5 — Great concept, short on delivery. *2023-04-15* I love the concept, but; You can not expand the text dialogue box; You can not see full text in the footnotes that it presents; It misspells; And, for some reason you are limited to the number of queries that you can make, like you are on a leash or something. Perhaps this algorithm is geared toward the corporate world, however it puts the artificial in artificial intelligence. ### 2/5 — Inaccurate reading of PDF *2024-02-01* Struggles with reading pdf information that is obviously in the PDF. ## Most praised reviews (10 highest-rated) ### 5/5 — Good *2023-11-06* Super helpful ### 5/5 — Excelente aplicación *2023-11-04* Me encanta! ### 5/5 — Süper *2023-10-27* Süper ### 5/5 — Pretty great even while free *2023-10-10* Works well and I don’t really find myself hitting the message limit under the free plan ### 5/5 — Does exactly what I wanted! *2023-09-16* Train your chatbot by uploading PDFs and use it to generate or answer questions. I love it!!! And I have had no problem copying text. Just right click on the chat response and it goes to your clipboard. It's exactly what I was looking for! ### 5/5 — Perfekt *2023-08-28* wow ### 5/5 — gut *2023-08-14* gtu ### 5/5 — Books *2023-08-12* I’m going to say that I read books, but not too often I even write about them and their key points, but nothing could prepare me to how much detail and description this app gave me. I have yet to buy it but I am for sure positive you need to ask the right questions once you get your book uploaded, I give you a five star is mainly because it was able to read the PDF I’ve already tried three other AI book readers already and this is already the best and cheapest I’ve seen so from now on, I would recommend this to anyone I will see I’ll look for to what this app will become ### 3/5 — Unable to login to an account created on desktop *2024-03-03* This is a cool platform on a laptop, but the app is too simple and doesn’t allow you an “account login” button on the main screen. The iOS version is a waste. ### 3/5 — Amazing *2023-11-21* So far it seems to be seamless in my research project. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
