Free tool
Paste your notes or a chapter. Get objectives, key terms, the concepts explained, the mistakes people make, and questions that hide their answers. Free, and it runs before it asks you anything.
What you should be able to do — phrased so you can test whether you can do it.
The vocabulary you need cold, each defined in one precise sentence.
The ideas themselves, explained rather than merely listed.
The specific errors students make on this material, and the corrections.
Questions with answers hidden until you ask, so you retrieve instead of recognise.
You have met the other kind. A confident generate button, a hopeful click, and then a signup wall where the study guide should have been. You give up an email to find out whether the thing is even any good.
Paste your notes here and you get the whole guide — every section, answers included, copy and download available — without an account existing. If it is useful you will know before we know your name.
Most tools in this category shorten your material and call it a guide. Shorter prose is still prose you read once, and reading is recognition — it feels like learning while very little sticks.
This separates what you memorise from what you explain, names where the material trips people, and makes you answer before it shows you anything. That last part is the one that does the work.
Every guide starts somewhere, and the four routes below end up with genuinely different objects in your hands. That is worth knowing before you spend an evening on one of them.
| Route | What you get | What it costs you |
|---|---|---|
| Write it yourself | The version you understand best, because building it is most of the revision. | Hours per chapter — and on a chapter you did not follow, you are structuring material you do not yet grasp. |
| Ask a chatbot | Fast, conversational, and you can ask follow-up questions about anything unclear. | The shape depends on how you phrased the request, so two attempts at the same chapter come back different. You also have to check all of it. |
| Run a summariser | Shorter prose in seconds — genuinely useful for the gist before a lecture. | It is not organised for recall, so it reads well once and then stops being useful. |
| Use a generator | One structure — objectives, terms, concepts, misconceptions, questions — applied to whatever you paste. | The structure is chosen for you rather than for your subject, so anything that does not fit gets left out. |
None of these is wrong. The first is what you would choose with unlimited time; the last is what gets a revision pass started tonight. Most people end up combining two — generate the structure, then correct it by hand, which is closer to annotating someone else’s notes than writing your own.
Lecture notes, a textbook chapter, a set of slides. Or drop in a PDF — it is read in your browser and the file never uploads. Up to 4,000 words, free, with no account.
One press. You get learning objectives, key terms, the core concepts explained, the mistakes people actually make on this material, and self-test questions with hidden answers.
Answers stay covered until you ask for them, so you practise retrieval rather than recognition. Copy it, download it, or keep the tab open through the week.
The generator reads what you give it, faithfully — which means a disappointing guide is nearly always an input problem rather than a tool problem. Four things fix almost all of them.
Guides go vague when the source spans too much. A guide built from three lectures has to generalise across all of them, and generalisation is the one thing you cannot revise from. Paste the chapter you actually have a test on. If you need a whole module covered, build several guides and work through them in order.
Slides and textbook chapters already have a shape, and it is usually the lecturer’s own. Paste it intact rather than flattening it into a wall of text — the headings tell the tool what the material treats as one idea, and they become the skeleton of the guide.
The guide is built only from what you paste, so the aside your lecturer repeated twice is worth including, and so is the worked example you copied down by hand. Notes you wrote in your own words are the strongest input available. Re-typing three bullet points is often the difference between a generic guide and one that sounds like your course.
Below about 120 words there is not enough material to find a structure in, and the guide will pad to fill the shape. Above 4,000, split it by chapter. The free allowance is 4,000 words per guide — a full textbook chapter, or a long lecture’s notes.
The questions sit at the bottom of the guide, and that is the wrong place to start reading. Read the first one and answer it from memory before you scroll anywhere — badly, if that is all you have. Then read the objectives and the key terms, and notice which parts of your answer were wrong. A guide read front to back tests nothing.
The order is deliberate. Answering first tells you what you do not know, which is the only thing worth knowing this close to an exam. Reading first tells you the material looks familiar, which it will.
Three twenty-minute passes across a week beat one three-hour session, and the questions make that easy to arrange because you can work through them in any order. Read the misconceptions section last and ask which of them you made — the errors on a given chapter are predictable and shared, and most of your cohort will have made several.
Stop when you can answer cold and explain the concepts out loud without the page. Past that point you are re-reading, which feels productive and is not.
Three months of lecture notes in no particular order. The guide gives them a shape you can actually revise from, in about ten seconds.
Reading is recognition; it feels like learning and mostly is not. Self-test questions turn the same chapter into retrieval practice.
For readers with ADHD or dyslexia the material is rarely the obstacle — the format is. A structured guide breaks a wall of text into pieces with edges.
Tutors and TAs use it to turn a reading into a handout: objectives at the top, terms defined, questions ready at the bottom.
What none of them get from a guide is the reading itself. That still has to happen — which is why the same chapter also converts into a chapter-aware audiobook you can listen to on the walk in. Guide for the revision pass, audio for the pass before it.
Paste the notes into the generator above and press build. You get learning objectives, key terms with definitions, the core concepts explained, common misconceptions, and self-test questions with hidden answers. It takes a few seconds and needs no account. For handwritten notes, photograph them with Google Lens or Adobe Scan first to get the text out, then paste that.
Yes — 4,000 words per guide, no signup, no card, and the whole guide is visible. That is a full textbook chapter or a long lecture's notes. Most tools in this category show you a generate button and then ask you to create an account before anything happens; this one runs first and asks nothing.
Five parts. Learning objectives, phrased as things you should be able to do rather than vaguely understand. Key terms with one-sentence definitions. Core concepts, each explained in a few sentences. Where people commonly go wrong on this material. And self-test questions whose answers stay hidden until you reveal them, because retrieving an answer is what makes it stick, and seeing one does not.
No, and the difference matters. A summary retells the material in fewer words — you read it once. A study guide is organised for recall: it separates what you must memorise from what you must be able to explain, and it makes you test yourself. If a tool hands you three shorter paragraphs, you were given a summary.
Yes. The PDF is read in your browser using its text layer, so the file itself never reaches a server. If it is a scan — photographs of pages with no text layer — nothing can extract text from it until it has been through OCR, and the tool tells you that at upload rather than producing an empty guide.
No, and it will not pretend to. Formulas, figures, and data tables cannot be represented in a text study guide without mangling them, so they are skipped. Use the guide for the concepts, terminology, and reasoning, and keep the book open for the maths. Any tool claiming to do more with a diagram is overselling.
One chapter or one lecture at a time, between roughly 120 and 4,000 words. Guides get vague when the source spans a whole module, because the tool has to generalise across too much. Several focused guides beat one broad one, and it is closer to how you will revise anyway.
Not directly — there is no Anki export, and a two-word card is a different object from a guide. What people do is copy the key terms and the self-test questions into whatever spaced-repetition app they already use. The guide is the part that is hard to produce on your own; the card takes a minute. If flashcards are the whole plan, a dedicated card maker is the better tool and we would rather say so.
A chatbot gives you whatever shape you ask for, so the result depends on how well you described what you wanted, and two attempts at the same chapter come back different. This applies one structure every time — objectives, terms, concepts, misconceptions, questions — and it is organised for revising rather than for reading. The free run also happens without an account, which is not true of most of this category.
Correct it. The guide is a first pass built only from what you paste, so an error usually traces back to a misread in the source or to a term your notes used loosely. That is also why the questions are the most useful part: an answer you cannot make match the guide is a signal that one of you has the material wrong, and it is worth finding out which before the exam rather than during it.
No. What you paste is used to build the guide and then discarded — not saved to an account, not used for training, not retained after the request. PDFs are parsed entirely in your browser and never uploaded at all.
The same material converts into a chapter-aware audiobook — front matter skipped, resumable across devices, downloadable as MP3s. Your first chapter is free at any length, no card.
