Paste a YouTube transcript, lecture notes, or upload the slide PDF. We turn it into a TL;DR, key bullets, three likely exam questions, and a glossary.
Tip: photo / PDF quality must be clear and well-lit — blurry or dark pictures can't be read by the AI.
Paste a lecture, a transcript or a long set of notes, and this free tool turns it into clean revision notes: key points, the definitions that matter, and what is worth memorising. If you have been looking for a way to summarise lecture notes, AI handles the compression; you still have to do the learning.
Set your board once and the notes come back in that board's language. For CBSE it keeps NCERT chapter wording, because 3 and 5 mark answers are marked on keywords. For GCSE (AQA, Edexcel or OCR) it tags points by command word, so you can see which lines answer describe and which answer explain in a 6 mark levels of response question. For AP it groups points by unit and flags what an FRQ would ask you to justify. For Cambridge IGCSE and International A Level it holds definitions in syllabus wording, since mark schemes there accept very little paraphrase. For WAEC it splits points into short numbered lines, which is how WASSCE theory answers earn marks.
Set your exam board — it takes about 30 seconds and every answer after that matches your syllabus.
I pasted in the transcript of a 40 minute biology lecture on enzymes, about 6,000 words of talking. Back came roughly 400 words: eight key points, six definitions (active site, induced fit, competitive inhibition, non competitive inhibition, Vmax, Km), and three questions the topic normally gets asked as. The useful bit was Km. My own notes had it as how fast the enzyme works, which is wrong, and I would have written that in a test. The summary had it as the substrate concentration at which the rate is half of Vmax, which is the version a mark scheme accepts. Then I covered the page and rewrote the eight points from memory. I got five. The three I missed went into flashcards, and that step, not the summarising, is what made them stick.
For compressing an hour of talking into a page you can revise from, yes, it saves real time. For learning the material, no, because reading a summary feels like understanding and is not. Use it to get the raw material into a usable shape, then close it and rewrite the key points from memory. The second part is where the marks come from.
It is free and there is no paid tier waiting behind it. You do not need an account to use it; you set your board and year once so the notes come back in the right style, and that is stored on your device. There is a daily cap on how many runs come from one internet connection, because the AI costs money to run, so everyone on the same school or home wi-fi shares it. Signing in does not change the cap, and it does not change this tool at all — summaries are not saved to your account, or anywhere else.
Good enough to revise from, not good enough to trust blind. Two failure modes come up often: it states a definition in general terms when your board wants a specific form of words, and it repeats a mistake that was already in your notes, confidently. Check every definition and every number against your textbook or the syllabus before you commit it to memory.
Yes. A PDF has to be under 3 MB, so upload the pages you need rather than the whole deck, and photos need to be sharp and well lit because the AI reads them the same way you would. Handwriting is the weak point: neat notes usually come through, but a rushed page scribbled in the margin often gets misread or skipped entirely.
Summarising a lesson you sat through is revision, the same as borrowing a friend's notes. Pasting the summary into a piece of assessed work and calling it yours is not, and most schools now treat that the same as copying. The line is simple: use it on material you are trying to learn, never on work that is being marked.
One topic at a time. A single lecture or one chapter comes back with enough detail to revise from; a whole term pasted in one go comes back as headings with nothing under them, because the model has to cut somewhere. If your transcript covers three topics, run it three times and you will get three usable pages instead of one thin one.
