An AI chemistry solver takes a chemistry question, typed or photographed, and works through it step by step, from balancing equations to stoichiometry and thermochemistry. Some are phone apps, some run in a browser and some cover every subject. Ten tools follow, in no particular order.
Chemistry homework has a habit of going wrong in the middle. You can usually see where a question starts and roughly where it should end, but a unit slips or a mole ratio goes the wrong way and the answer falls apart.
That's where a step-by-step solver helps, as long as you use it to check your method. The ten tools below are listed alphabetically and in no particular order, and each description comes from the tool's own website or App Store listing, read this week.

AI chemistry solvers at a glance
I checked the free plan column on each tool's own website or App Store listing, as of Oct 2026. Yes means the page names a free plan, a free tool, a free version or a free tier. Trial only means a time-limited trial. Not stated means the page I read named neither, even where there's a try-free button, so check the provider's own page before you sign up.

Ten AI chemistry solvers worth a look
AskSia
Best for: Anyone working through thermochemistry, with worked steps for enthalpy, Hess's law and Gibbs free energy problems.
Chem AI
Best for: Phone-first learners who want an app that works through multiple choice, word and diagram questions step by step.
Chemistry AI: Homework Helper
Best for: Learners who'd rather photograph a question than type it, with a scan-to-solve feature and a short free trial.
Chemistry Solver
Best for: Learners who want an AI tutor to guide them through a problem step by step rather than just show the final answer.
Gauth
Best for: Pupils who need help across every subject, chemistry included, from one well-known study app.
Mindko
Best for: Laptop users who like help in the browser, with a free chemistry solver in a wider study set that includes a Chrome extension.
Overchat
Best for: Curious students who want to put a chemistry question to more than one AI model, since it offers several in one place.
SimpleTools: Chemistry Solver
Best for: Parents helping with homework and students with the odd tricky question, since free users can solve one problem a day.
Studdy
Best for: Revisers who want to upload notes, textbooks or study guides and get one-to-one help on a whiteboard-style tutor.
Wolfram|Alpha
Best for: Students who need reliable data on chemical compounds, reactions and calculations rather than a chatty explanation.

Which solver for which student
- You'd rather photograph the question: Chemistry AI: Homework Helper.
- You want to compare AI models: Overchat.
- You need compound data you can trust: Wolfram|Alpha.
- You're stuck on thermochemistry: AskSia.
- You want to work from your own notes: Studdy.
How chemistry exams reward your working
College Board's outline of the AP Chemistry exam shows why the steps matter more than the answer. There are 60 multiple-choice questions in 1 hour 30 minutes, worth 50% of the score, and 7 free-response questions in 1 hour 45 minutes, worth the other 50%.
Those free-response questions are 3 long-answer questions worth 10 points each and 4 short-answer questions. With 10 points on each long answer, showing a clear method matters, and a solver that only gives you the final value won't teach you how to lay it out.
Where AI solvers slip up
- Units: check that every quantity carries its unit through to the end.
- Rounding: AI answers often give too many digits, so round to the precision the question's data supports.
- Diagrams: structures and lab set-ups are easy to misread from a photo, so type the question when you can.
- Data: use the values your teacher or exam board gives you, not ones the AI looks up.
A three-step way to use a solver
- Try the question yourself and write down where you got stuck.
- Ask the solver for the steps, not just the answer, and compare them line by line with yours.
- Close the solver and redo the question from scratch, then try a similar one.
Do you make AI homework, chemistry or science tools? Tool makers can ask to be considered for a featured place on this list.
My plain advice on AI chemistry solvers
Use a solver as a marking partner, not a shortcut. Try every question first, then check the method step by step and redo it without help, because that's the only way the working sticks for an exam.
Check units and rounding on every AI answer, and type questions with diagrams rather than photographing them. For revision prompts you can use alongside any solver, see my list of ChatGPT prompts for students.
Frequently asked questions
What is the best AI chemistry solver?
It depends on how you work: photo apps suit quick homework checks, while browser tools and data engines suit longer problems.
Are there free AI chemistry solvers?
Yes, several tools here name a free solver or a free daily problem on their page, so check the free plan column.
Can AI solve chemistry problems correctly?
Often, but not always. Check units, rounding and any data the question gives you before you trust an answer.
How is the AP Chemistry exam structured?
College Board says it has 60 multiple-choice questions in 1 hour 30 minutes and 7 free-response questions in 1 hour 45 minutes, each half worth 50%.
Can I photograph a chemistry question?
Yes, several apps here solve from a photo, though typed questions are safer for diagrams and structures.
Is using an AI chemistry solver cheating?
It depends on your school's rules. Using one to check your own method is usually fine, but copying answers for graded work often isn't.
