I used to spend 3 hours making flashcards. Now I paste my lecture notes and Duetoday does it in 10 seconds. My GPA went from 2.8 to 3.7.
I uploaded my case notes and asked it to compare two judgments. It found connections I had completely missed. Saved hours of prep before my tutorial.
The YouTube to flashcards feature alone is worth it. I convert entire revision playlists into study sets instantly. Nothing else does this.
My lectures are in English but I think in Cantonese. Duetoday handles both — I ask questions in Cantonese and get answers that actually make sense to me.
I asked it to quiz me on everything from my recorded algorithms lectures. It generated 40 MCQs from what my actual lecturer said. Passed my midterm without reading the textbook once.
I watch CrashCourse the night before exams. Duetoday turns 18 minutes of video into flashcards I can actually drill. Passed my biochem final for the first time.

The Chrome extension is absurdly good on research papers. I open a paper, click the panel, and get a structured breakdown — methodology, findings, key terms — in seconds. I don't read papers the old way anymore.
Legal lectures move fast. Duetoday captures every case name and statutory provision my lecturer mentions — and I can search them instantly. Used to take me 3 hours per lecture.
Asked it 'what should I focus on for Friday?' and it gave me a ranked list based on what appeared most in my notes. That's not something ChatGPT can do — it has no idea what my actual lectures covered.
My lectures are in English but I study in Portuguese. Duetoday gives me everything in Portuguese — notes, flashcards, everything. It's like having a translator and study partner in one.
I had two semesters of Notion notes sitting there doing nothing. I imported everything into Duetoday and had a complete flashcard deck in about ten minutes.
I upload the lecture recording and by the time I get home, I have a full set of notes and quizzes ready. My study sessions used to start with setup. Now they just start.

I used to have 15 tabs open trying to study one YouTube lecture. Now I paste the link and have structured notes and flashcards before the video is even half done.
The live transcription is wild. I use it in seminars — just click record and I have a full transcript and structured notes by the time I leave the room.
I asked it to explain protein synthesis from my own lecture notes and it gave me a better explanation than my textbook. And it cited the exact timestamp in my recording.
I can ask questions about my notes at 2am before an exam and get answers that actually reference what my lecturer said — not a textbook version of the topic.
My lecturer posts YouTube recordings of his lectures. I paste the link and within seconds I have structured notes and a quiz. I've stopped re-watching the same video three times.
Drug names and mechanisms are brutal to memorise. I paste my lecture slides and Duetoday generates flashcards with the exact wording my lecturer uses. My pass rate went up immediately.
