Heddy vs Question.AI: a solver that's free, or a tutor that's slow

Question.AI will answer almost any homework question, in almost any subject, for almost nothing. That is a genuinely useful product and it is not a tutor. Which of those you need depends on whether the problem is tonight or in June.

At a glance

What Question.AI does better

It's free and it's fast, which together are hard to argue with when it's late and there's a deadline.

It covers subjects we don't. Economics, business studies, computer science, a language we don't teach. Heddy has seven subjects and stops; a general solver has a go at everything.

It handles a typed question well. Not everything is photographable — sometimes the problem is a paragraph of a question you half-remember from a lesson, and a general model handles that gracefully.

It has no age or country gate. Heddy is 13+ and UK-only, which rules it out for a lot of people who can use Question.AI today.

What a free answer actually costs

Not money. Time, later, and it's paid in an exam hall.

An answer with reasoning attached is the most seductive form a study tool can take, because reading correct reasoning feels exactly like understanding. But the thing that makes knowledge durable is retrieval — producing an answer from nothing and feeling the effort of it. Reading is recognition. Recognition doesn't survive to a closed-book paper, and you find that out at the worst possible moment.

This is a mechanical claim, not a moral one. The student who copies twelve answers and the student who reads twelve solutions attentively both end up with a similar gap, and only one of them meant to.

What Heddy does instead, and what it costs you

You get a question back before you get help. Then a narrower one. Then the method, named. Then, at the top of the ladder — with nothing above it — a fully worked similar problem, and now redo yours.

You never receive the solution to your own question. Not because we're withholding it as a growth tactic, but because the transfer from a twin to your own numbers is the entire learning event, and no solved version of your question can contain it. The full argument.

The honest cost: it takes minutes rather than seconds, and it's frustrating in exactly the way that being taught properly is frustrating. If tonight's problem is a volume of homework and a deadline, a solver will serve you better, and I'd rather say so than pretend.

The bit a solver has no version of

Question.AI answers and the encounter ends. There is no memory of what you got wrong, because there's nothing that persists between questions.

Heddy's sessions produce flashcards written by the professor who watched you make the error — with the misconception recorded on them, scheduled to come back before you forget. And in three weeks, when one of those cards still won't stick, you can carry that exact card back into his room with the question already asked.

That loop is the product. A solver optimises for the next four seconds; the loop optimises for whether you can do it unaided in June.

Which to choose

Question.AI if it's free that you need, your subject isn't one of our seven, you're outside the UK or under 13, or the honest task is clearing a backlog.

Heddy if you keep getting the same kind of question wrong, and want that to stop rather than to be answered again.

And if you use both: use a solver to check work you've genuinely attempted, and a tutor when you're stuck rather than unsure. Those are different failures and they want different tools.
