I have been learning Japanese for a quarter now, and as much as I enjoy having GPT explain things I am confused about without Googling, I am REALLY fed up with switching between Acrobat and ChatGPT, especially when doing exercises inside my PDF material. Here is my actual workflow: 1. Screenshot the exercise page without my answers and upload it to ChatGPT so it will have context. 2. Go back to Acrobat and deal with its text insert feature...this text insert feature itself is an annoyance on its own. 3. Screenshot my attempt and send it back to ChatGPT so it can grade my answers. See my mistakes and ask any follow-ups. 4. Go back to Acrobat, mark my wrong answer red, and paste in the explanation with comment features so I can revisit later. 5. Repeat this for each page of the exercise Looking back, I spent around 20% of my study session just on this back and forth, the flow disruption is obvious, but the time wasted annoyed me more. If I can only spend one and a half hours per day for Japanese learning, I would rather spend as much time as possible on the actual learning! So, this \*having GPT answers my question right inside the PDF\* is just a proof of concept. You select the things you are confused about, ask questions, follow-ups, etc. The exchanges between you and AI will be saved. And this alone excites me because the questions you asked reveal precisely what you are struggling with, so these logs are perfect for a more personalized learning experience(potential feature). There are already similar tools out there that can do this, like ChatPDF, but I want to build this thing for Japanese language learning. I am currently tackling the answer mode, where I can answer directly inside my PDF, and have AI grade it right there. Feeling excited!
