The tool below takes that line seriously. Paste your problem set and it hands the questions back to you as prompts, with the answer left blank unless your own text contained one.
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.
Problem set to self test
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.

This tool uses text rules, not AI. It keeps a numbered question whole with its options rather than splitting them into useless fragments, matches an answer line such as "Answer: A" to the question above it, and otherwise leaves the back of the card empty. It does not solve anything, and that is deliberate: a helper that hands you the answer removes the only part of homework that teaches you something. Your text stays in the browser and is never sent anywhere.
One question decides whether you are allowed to do this
Ask what the homework is being marked for. If it is marked for the answer, as with a graded problem set that counts toward a module, then getting the answer elsewhere is the thing your institution defines as misconduct, and the definitions are public: see the International Center for Academic Integrity and the general treatment of academic integrity. If it is marked for practice, as with an untracked exercise set before an exam, the answer is worthless anyway and only your ability to produce it counts. Most policies now name AI assistance explicitly and most of them turn on disclosure rather than on prohibition, so the safe move is boring: read your own course's wording before you paste anything, not after.
The worked example is the legitimate use, and it has rules
Studying a fully worked solution genuinely beats struggling unaided when the material is new, which is one of the better replicated findings in instructional research, the worked example effect. The mechanism is load: a novice who has no schema for the problem spends everything on search and has nothing left for the structure, the argument set out in cognitive load theory. The rule that comes with it is fading. Worked examples help early and stop helping once you can do the steps, at which point they become a way to feel competent without being tested. Alternate them: read one solved, do the next unaided, and the moment the unaided one works, stop reading solutions for that problem type.
Where a model is unreliable, specifically
Three failures show up often enough to plan around. Arithmetic and unit conversion inside a longer chain, where the method is right and one step is silently wrong. Citations, where a plausible author, year and title are produced for a paper that does not exist, the failure called hallucination. And confidently reconstructed method, where the answer follows a standard approach that your course does not use, so the working is marked wrong even where the number is right. None of these look like errors while you read them, which is the problem: fluent text produces the fluency heuristic, where ease of reading is mistaken for correctness.
Checking an answer you did not derive
Four checks, in order of how much they catch per minute spent. Substitute the result back into the original condition, which catches most arithmetic slips outright. Check units and rough magnitude, because a plausible method with a wrong power of ten is common and obvious once you look. Redo the single step you understood least well, rather than the whole chain. Then explain the solution aloud to nobody in particular, the technique programmers call rubber duck debugging, which works because the gap in your explanation arrives before the gap in your understanding does. Explaining to a person is stronger still, since teaching the material forces the organisation that reading never demands.
Help at the right level, which is just above where you are
The useful size of a hint has a name. Vygotsky's zone of proximal development is the band of problems you cannot do alone but can do with support, and support that lands outside that band is wasted in both directions: a full solution to a problem you nearly had removes the learning, and a cryptic nudge on a problem you have no footing in removes the confidence. Scaffolding is the practice of giving the smallest hint that unblocks you and withdrawing it as soon as it is not needed. In practice ask for the next step only, never the answer, and ask for the principle before the step. The reason personal help is worth this much care is Bloom's two sigma problem, the finding that one to one tutoring moved average students far up the distribution of a conventionally taught class.
Turning tonight's homework into next month's revision
A finished problem set is the best revision material you will ever have, and almost everybody throws it away. The questions were chosen by whoever writes your exam, they are pitched at your level, and you already know which ones hurt. Paste the set into the tool above and you get them back as prompts with the answers blank; work through those a week later and you are running formative assessment on yourself rather than rereading a solution you have already seen. Keep the ones you got wrong in their own pile, since deliberate practice is defined by working at the edge of failure rather than repeating what already works. Note that a multiple choice question you can answer by elimination is testing you far less than the same question with the options covered.
What the app does with a problem set
Photograph the sheet, upload the PDF or take a camera shot and WeSolve+ reads the file itself, then writes an explained quiz from it, builds a card deck and produces an audio recap of roughly one minute. Explained means the reasoning is shown rather than a bare letter, which is the difference between checking an answer and understanding it. Wrong answers collect in their own list so the next session begins with them. It runs at wesolveapp.com in any browser and as an App Store app on iPhone and iPad. Free to start, with two quizzes and two uploads a day, two recaps a week and two duels a day. There is no separate Android app. Numbers on pricing.

| What you were set | Use that helps you | Use that costs you the grade |
|---|---|---|
| A graded problem set | Ask for the next step after you are stuck | Paste the question, hand in the output |
| An essay | Argue against your own draft | Generate paragraphs and edit them |
| A proof or derivation | Check your finished proof for gaps | Request the proof, then learn it |
| Practice questions before an exam | Anything, they are not marked | Reading solutions instead of doing them |
| A lab report | Check units, structure and conventions | Inventing data or a discussion |
Does the tool solve my homework?
No, and that is the point. It converts your questions into prompts and leaves the answer blank unless your own text contained one. A helper that supplies the answer removes the part of homework that teaches you something.
Is using AI for homework cheating?
It depends entirely on what the work is marked for and what your institution's policy says. Marked for the answer means the answer must be yours. Most policies now address AI explicitly and most turn on disclosure, so read yours before you paste anything.
Is anything I paste uploaded?
No. The tool is a script on this page and makes no network request, which you can confirm in the network tab. Closing the tab ends it.
Why does it keep multiple choice options with the question?
Because splitting them produces four meaningless cards. The question and its options are one item, and an answer line such as "Answer: A" beneath them is matched to it.
When is a worked solution the right thing to read?
Early, when the material is new and you have no method to apply. It stops helping once you can do the steps, and after that it mostly produces the feeling of competence without the test of it.
How do I check an answer I did not derive?
Substitute it back into the original condition, check units and magnitude, redo the step you understood least, then explain the whole thing aloud. The gap in your explanation shows up before the gap in your understanding does.
