Turn lecture notes into a study guide
that shows you where every line came from.
Paste the lecture. You get sections in the order the material was taught, each one sitting on the sentence in your notes it was built from.
No account, two guides a day, up to 25,000 characters free.
Open any question to see the line it came from. Paste 40 characters or more to start.
The problem with an AI summary is that you cannot check it
Every tool in this category will hand you a tidy document. The question nobody answers is what happens when one paragraph is subtly wrong — a date shifted by a decade, a condition attached to the wrong process, a definition that belongs to the neighbouring term. You revise from it anyway, because a confident paragraph reads the same whether or not it is true, and you find out in the exam.
So this one is built the other way round. A section only exists if a sentence supporting it can be found, character for character, in the text you pasted. The model does not get to introduce a fact from its own memory of the subject, because a fact with no matching sentence in your notes is dropped before it reaches the page. Open the source line under any section and you are looking at your own lecture, with the relevant sentence highlighted inside it.
The visible cost of that rule is length. A guide that discards everything it cannot ground is shorter than one that does not, and occasionally it is much shorter — which is itself information. A lecture that yields four sections instead of twelve was mostly worked examples and asides, and no summary was going to compress it usefully.
What a guide is for, and what it is not
Reading is not testing. A study guide gets the shape of the material into your head: what the topics are, how they connect, which condition attaches to which process. It is the thing you read on the train the morning before, and it is genuinely good at that.
It is bad at telling you whether you actually know any of it. Recognition feels like knowledge while you are reading and stops feeling like it the moment someone asks a question with the page closed. That is the job of the quiz and flashcard modes above the paste box — same notes, same paste, different output. The sequence that works is read the guide once, generate a quiz from the same text, and let the questions you miss tell you which sections to re-read.
Getting a usable guide out of a PDF
A lecture handout is usually a PDF, and PDFs come in two kinds. One was exported from software and carries a text layer: click-drag across a line in your reader and a highlight follows the cursor. That kind pastes in cleanly, and the upload button will read it without the file leaving your browser.
The other kind is a photograph or a scan. It looks identical on screen and contains no text at all, only pixels arranged to look like letters. Nothing highlights when you drag. No study guide generator from PDF can read it — ours included — and we would rather say that than return a guide built on garbled OCR you have no way to audit.
One more thing worth knowing about handouts: slide decks exported to PDF tend to produce weak guides, because a slide is already a compression of the lecture. Two words on a bullet do not carry enough for anything to summarise. If you have both the slides and your own typed notes, paste the notes.
Before you paste the lecture in
How is this different from asking ChatGPT to summarise my notes?
A chat window gives you a block of prose and no way to check it. Here every section carries the sentence from your own notes that it was built on, and you can open it inline. Sections whose source sentence cannot be found verbatim in what you pasted are discarded before you ever see them, so the guide is shorter than a chatbot summary and every line of it is traceable to your material.
Can I use it as a study guide generator from PDF?
Yes. Open the PDF, select the text, and paste it in — or use the file button, which reads the text layer in your browser without uploading the file. Scanned PDFs are the exception: a photographed page is a picture of text, there is no text layer to read, and we do not run OCR. If you cannot click-drag to highlight a line in your PDF reader, this tool will get nothing out of it either.
What order do the sections come in?
The same order as your notes. Section one covers the earliest material and the last section covers the latest, so the guide reads as a condensed version of the lecture rather than a re-ranked list. That matters when the notes build on themselves and a shuffled summary would explain step four before step two.
How long can the notes be?
Free reads up to 25,000 characters, which is roughly one lecture or one chapter. Longer notes get trimmed to that and the page says so rather than silently dropping the end. Splitting a semester into one lecture at a time also produces a better guide than feeding in everything at once — you get sections on each topic instead of one thin pass over all of them.
Will it catch everything important?
No, and it is worth being honest about that. It condenses to at most twelve sections, so a dense chapter loses detail by design. It is a revision scaffold to read before an exam, not a replacement for the notes — keep the original open next to it. If a topic you expected is missing, that usually means your notes covered it in one passing clause rather than in a way anything could summarise.
Can I turn the guide into practice questions afterwards?
Switch the mode above the paste box and generate again from the same text. Reading a guide and testing yourself on it are different jobs: the guide gets the material into your head, the quiz tells you whether it stayed there. Doing both from one paste is usually a better hour than reading the guide twice.
