Comparison · updated September 2026
The best free AI homework helper — honestly compared.
Most "free" homework apps aren't. Photomath solves the problem but locks the steps behind Photomath Plus. ChatGPT is generous, but the good model costs $20 a month. Quizlet moved its best study modes behind a paywall. We built Fastie because we were the students hitting those walls — so here's the honest breakdown.
What "free" actually means in 2026
When students search for a free AI homework helper, they usually want three things: snap a photo of the problem, get the answer, and see the steps so the teacher's "show your work" requirement is covered. Most apps give you one of the three for free. The table below shows who gives you all of them.
| Feature | Fastie | Photomath | ChatGPT | Quizlet |
|---|---|---|---|---|
| Price | Free forever | $9.99/mo for steps | $20/mo (Plus) | $7.99/mo |
| Snap a photo of homework | ||||
| Step-by-step work shown free | ||||
| Answer first, work optional | ||||
| Flashcards built in | ||||
| Smart notes | ||||
| Quiz generator | ||||
| Syllabus / deadline tracker | ||||
| Unlimited messages, no card |
Where each one wins
Photomath is still excellent at recognizing printed equations. But the explanation — the part that actually teaches you — requires Photomath Plus. If you only want to check an answer, it works; if you want to understand it, you pay.
ChatGPT is the strongest general-purpose brain on the list, but the free tier limits you, the Plus plan is $20/month, and it answers in paragraphs. You always get the lecture before the answer.
Quizlet owns flashcards — but it can't read a photo of your worksheet, and Learn mode moved behind Quizlet Plus.
Fastie was built around one idea: answer first, work optional. Snap a photo or paste the question, get the final answer in about 2 seconds, then tap Show work only if you want the steps. Flashcards, smart notes, a quiz generator and a syllabus tracker live in the same tab — free, unlimited, no credit card.
The verdict
If budget is zero — and for most students it is — the best free AI homework helper is the one that doesn't gate the learning. Fastie is free because we think paywalling the explanation is backwards. Try it on your next worksheet and judge for yourself.
