The tool below is the free entry to that and needs no account.
WeSolve+ reads the whole document and writes the questions for you
Upload your PDF, photograph your notebook, or point the camera. WeSolve+ writes questions from that material, explains why each answer is right, reads the chapter back to you as a podcast, and remembers every item you missed until you own it.
The tool below is a small browser-only tool and it is not WeSolve+: paste a few lines and text rules turn them into cards on the spot. The real app, the one that uses AI, is behind the link above.
Your file, not a library
This is a browser-only tool, and that is all it isIt splits the text you paste by rule, and nothing else. WeSolve+ is a different thing entirely: it reads your whole PDF with AI, writes the reasoning behind every question, speaks the chapter back to you, and remembers what you missed so it can return it. Try the real app now, free!
This tool uses text rules, not AI, and it has no library at all. That is the difference this page is about: a library helps when the set exists, and does nothing when the material is a handout only your class received. Your text stays in the browser and is never sent anywhere.
| Your situation | A library helps | A file reader helps |
|---|---|---|
| Standard course, common textbook | Yes, immediately | Yes, but slower than searching |
| Your lecturer's own handout | No, it is not there | Yes, that is the case it is for |
| You want it free | Knowt is built on that | Free tier, metered by file |
| You need the emphasis of your class | Only by luck | It comes from your document |
| You want wrong answers tracked | Varies by product | Kept in their own list |
| You have twenty minutes and no set | Search first | Upload first |
Knowt is answering the pricing question, not the sourcing one
Its own homepage leads with being a free alternative, and the product follows from that: a large shared library, a set maker, and exam pages built around the courses most students take. If your complaint about Quizlet was the paywall, that complaint is addressed. What stays unaddressed is the case where the set does not exist, because no library holds the twelve page handout your lecturer wrote last week, and that case is not rare.
The two questions are genuinely different
Ask which of these describes your evening. Either the material is standard, in which case somebody has made the set and the job is finding a good one, or the material is specific, in which case the job is making one and finding is impossible. Libraries are excellent at the first and structurally unable to help with the second. Tools that read a file are the reverse: they cannot hand you a ready deck for AP Biology in four seconds, and they can turn your own chapter into questions in about thirty seconds. Most students meet both cases in the same week, which is why this is not a contest.
What a shared library costs you, quietly
A downloaded set is somebody else's judgement about what matters, written for their syllabus and containing their errors. That is fine for vocabulary and dangerous for anything where emphasis matters, because you cannot see what was left out. Knowt's flashcard side makes the same trade every library makes: speed now, unverified selection later. The countermeasure is not to avoid libraries but to treat a downloaded set as a first draft, delete what your course does not cover, and add what it missed.
Where the two overlap, honestly
Both products will take a document and produce study material from it, and Knowt has an AI summariser alongside its library. This page is not going to claim that capability does not exist. The difference is what the product is organised around: Knowt is organised around a library with generation attached, WeSolve+ is organised around your file with nothing else attached. That shapes the defaults rather than the feature list, and defaults are what you actually live with.
What WeSolve+ does with the file
Upload a PDF, a photograph of a page or a camera shot and it writes an explained quiz, a card deck and a spoken recap of about a minute from that single source. Explained means the reasoning travels with the item, so a card you get wrong points back at the page that produced it. Wrong answers collect in their own list, cards return on a schedule, and you can duel a friend on questions drawn from your own material. Starting is free on the web and on iPhone, metered by file rather than by card. Figures on pricing.
Which to pick, in one line each
Take Knowt if your subjects are standard, you want sets without paying, and the library covers your course. Take WeSolve+ if the material arrives as a file, if the emphasis in your class differs from the textbook, or if you want the wrong answers tracked rather than the sets stored. Take both if your week contains both cases, which for most people it does. Nothing here requires choosing a side, and any page that tells you otherwise is selling rather than comparing.

Is Knowt really free?
Its own homepage leads with being a free alternative, and that is the question it is built around. What any tier includes today is a question for their pages rather than for a competitor's, because a figure quoted here goes stale the day it changes.
Does WeSolve+ have a shared library?
No, and not by omission. It is organised around the file you upload, which is the case a library cannot cover. If the set already exists, a library is genuinely the faster route.
Can Knowt read a PDF too?
It has an AI summariser alongside the library, so this page is not claiming the capability is absent. The difference is what each product is organised around, which shapes the defaults rather than the feature list.
Which is better for AP courses?
If a good set exists for your exam, a library wins on speed. If your teacher's emphasis differs from the standard set, questions from your own notes will match the paper you actually sit.
Should I use a downloaded set at all?
As a first draft. Delete what your course does not cover and add what it missed, because a set you did not write is somebody else's judgement about what matters.
Does this page's tool store anything?
No. It runs in your browser, keeps nothing and needs no account, so copy the output before closing the tab.
