The tool below is the free version of the narrow job.

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.

Start free!

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.

Lines to a deck

Paste your notes

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 does exactly one thing: turns pasted lines into two sided cards. Everything on this page about narrow tools applies to it too, including the limits. Your text stays in the browser and is never sent anywhere.

What each shape gives you after the cards exist

After generation	Single purpose tool	WeSolve+
Deck in your hands	Yes, that is the job	Yes
Which card comes back when	Your other tool	Built in
Wrong answers kept apart	No	Their own list
Card linked to its source page	Usually lost on export	Kept
A quiz from the same file	No	Yes, explained
Setup cost	None, and that is the appeal	An account

The case for narrow, stated fairly

A tool that generates cards and nothing else is easier to evaluate, faster to learn and harder to get wrong. StudyCards AI is built that way and the design has real advantages: there is no onboarding to sit through, no features you will never open, and the thing it does is the thing on the homepage. Narrow tools also fail visibly rather than quietly, since when the one job goes wrong you notice immediately. Anyone who already has a review system and only needs decks fed into it is well served by this shape, and their pricing page is the place to check what it costs.

What a deck alone does not do

Generating cards is the visible half. The half that decides your exam result is what happens afterwards: which cards come back, when, and whether the ones you keep missing are treated differently from the ones you know. A deck without that is a list, and studying a list means reviewing everything at the same frequency including the items you already know cold. The mechanism that fixes it is spaced repetition, resting on the measured shape of forgetting, and it is either in your tool or in a second tool you have to run alongside.

Two narrow tools is not the same as one wide one

The obvious answer to the section above is to pair a generator with a scheduler, and it works: generate here, export, import into a scheduler. It costs an export and an import each time, and that friction is exactly what stops people after three weeks. It also breaks the link between a card and where it came from, so when an item confuses you there is no page to return to. Whether that matters depends on your subject: for vocabulary it rarely does, for anything with a derivation it does immediately.

The generation step is not the differentiator anymore

Any product with a language model behind it can turn a chapter into cards, and the quality differences between them are smaller than the marketing suggests. What still varies is the honesty of the output: whether items trace back to the source, whether an explanation travels with the card, and whether the product tells you when it is unsure. That last one is rare and worth looking for, because a generator that never admits uncertainty is one you cannot calibrate against.

What WeSolve+ adds after the deck

The same upload produces an explained quiz and a short spoken recap alongside the cards, and every item stays attached to the page it came from. Wrong answers collect in their own list so a session opens with what failed rather than what already works, and cards return on a schedule rather than when you remember them. You can also duel a friend on questions drawn from the same file. Starting is free on the web and on iPhone, metered by file. Figures on pricing.

Which to pick

Take a single purpose generator if you already have a review system you trust, want decks fed into it, and value having nothing else in the way. Take WeSolve+ if you do not have that system, or if you want the wrong answers tracked and the source kept. Neither choice is about which tool generates better cards, because that difference is now small; it is about whether the tool ends at the deck or continues past it.

Is a narrow tool worse than a wide one?

Not at all. It is easier to evaluate, faster to learn and fails visibly. It is worse only when the one job is not the whole job, which is the case once the deck exists and has to be reviewed.

Can I just pair a generator with a scheduler?

Yes, and it works. It costs an export and an import each time, and it breaks the link between a card and the page it came from, which matters more for derivations than for vocabulary.

Are generated cards from different tools very different?

Less than the marketing suggests. What still varies is whether items trace back to the source, whether an explanation travels with the card, and whether the tool admits uncertainty.

What does WeSolve+ do that a generator does not?

Everything after the deck: scheduling, a separate list for what you keep missing, an explained quiz and a short recap from the same file, and a link back to the source page.

Is the tool on this page a narrow tool?

Yes, and deliberately. It turns pasted lines into cards and stops, so everything this page says about narrow tools applies to it too, limits included.

Does it store my cards?

No. Copy the output before closing the tab, because nothing is kept between visits.
