Calculus is the subject where recognition impersonates knowledge most convincingly. What you get back is built out of your own file, not a generic problem bank.
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.
Turn your calculus notes into cards
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!
Text rules, not AI. Lines with a colon become two sided cards; other lines lose their longest word. Nothing you paste leaves the browser. Copy gives tab separated rows for Anki.
Theorems have conditions, and the conditions carry the marks
Every named theorem in this course arrives with a fence around it. The Mean Value Theorem needs continuity on the closed interval and differentiability on the open one, and a student who states the conclusion without the fence has answered a different question. The same is true of the Intermediate Value Theorem and of the conditions under which a limit exists at all. These are short pieces of text, they are easy to half remember, and they are precisely the kind of thing that improves when you are asked to produce them rather than shown them again.
Your own worked problems, with the working hidden
A solved problem set is the strangest study material you own. Everything you need is on the page, and reading it teaches you almost nothing, because your own working answers the question before you have started thinking. Photograph the page or upload the file and the app builds questions out of it: which rule applied at which step, what the derivative of that inner function was, why the substitution was legal. The scaffolding disappears and the thinking has to happen again.
Notation that survives being turned into a question
Limits, integrals, superscripts and the difference between a prime and an apostrophe all matter, and material that flattens them into plain text becomes unreadable at exactly the moment you need to read it. Notation from your file is carried through rather than stripped, so a generated question about a definite integral still looks like a definite integral. That sounds small until you have tried to revise from a set of cards where every exponent has quietly vanished.
October theorems in a May exam
Limits and continuity arrive at the start of the year and are examined at the end of it, which is the widest gap in the course. Cepeda and colleagues, in 2008, looked at how far apart reviews should sit and found that the useful spacing scales with how long the material has to survive. For a May exam that argues for a deliberate return to the September material in February, when nothing is forcing you to, rather than a panicked reread in April. The app schedules those returns; the copy button exports them if you prefer to schedule elsewhere.
Where the calculator policy and the format live
This page does not tell you which sections allow a calculator, how long each part runs or how the two halves are weighted. Those rules belong to the College Board, they are published on the pages linked below, and they are revised. A calculus student who plans a revision timetable around a stale weighting loses weeks, which is a good reason for a study page to point at the awarding body rather than paraphrase it from memory.
Using it in the twenty minutes you actually have
The box at the top of this page opens in a tab, takes pasted text and closes again. No install, no account, nothing stored, which makes it usable on a school machine between lessons. For a problem set PDF you want the app, reachable at wesolveapp.com or through the App Store on iPhone and iPad. It starts free: two quizzes daily, two uploads daily, two recaps weekly, two duels daily, and however many cards one file supports. On Android the site is the route.

| Calculus material | Text rules on this page | AI reading the file |
|---|---|---|
| Typed theorem statements | Two sided cards instantly | Cards plus questions on the conditions |
| Photo of a worked problem | Cannot read a photo | Questions with the working hidden |
| Problem set PDF | Cannot read a PDF | Questions about each step |
| Notation heavy notes | Plain text only | Notation carried through |
| September material in February | None, you export | A scheduled return |
Can it make questions from my worked solutions?
Yes, if the page is a PDF, a photograph or a camera shot. The app hides your working and asks about the steps, which is the part rereading your own solution cannot do.
Does mathematical notation survive?
Notation from your file is carried through rather than flattened into plain text, so integrals, exponents and primes stay readable in the generated question.
Where do I check the calculator rules?
On the College Board pages linked in the sources below. We do not restate the section rules or weightings here, because they belong to the awarding body and are revised between cycles.
Will it solve calculus problems for me?
That is not what it is for. It turns your material into questions you answer yourself. A solution you did not produce is a solution you cannot reproduce in an exam room.
Is the box at the top free?
Yes, with no account and no limit, because it never contacts a server. The app is free to start with daily limits on the free plan.
