Mathos
AI math tutor with Snap & Ask photo solving, step-by-step hints, and knowledge graph progress tracking for K-12 students and teachers.
Mathos is one of the few math AI tools that treats the teacher as a first-class user, not an afterthought — auto-grading plus progress summaries is the kind of thing that actually buys back a planning period. The Snap & Ask flow and knowledge graph tracking are legitimately useful for middle and high school practice, and the 50M+ question volume suggests real classroom use rather than a demo. It is not a college math engine, and anyone who wants a one-line answer will find the Socratic approach

Skip Mathos if you need college-level or advanced math, require offline/desktop access, want a no-frills answer only, or if schoolwide integration with Google Classroom or Canvas is essential.
While a free tier exists, clear pricing for premium plans is not published, leaving potential subscription costs unclear.

Compared to Photomath (also freemium) or premium tutors, you get learning-oriented tools at no cost. However, schools requiring budget clarity may find the lack of published paid plans a drawback, while competitors often list clear per-student pricing.

About Mathos
Mathos is an AI math tutor built for K-12 students and the teachers who support them, and its entry point is deliberately low-friction: snap a photo of a handwritten or printed problem and the app responds with a hint, a Socratic question, or a walked-through solution instead of a bare answer. The stated goal on the vendor page is progressive learning, so the assistant nudges you toward understanding the concept rather than copying a result. Everything happens on web, Apple App Store, and Google Play, so a student can start on a Chromebook at school and finish on a phone at home. The vendor reports 50M+ questions asked by users across 200+ countries, and its beta math model is claimed to solve math with 20%+ higher accuracy than GPT-4 — early access to that model is gated behind a signup. The student side leans on knowledge graph profiling. Mathos tracks which skills you've mastered and where you're still stuck, then points you at the problems most likely to close those gaps, with bite-sized tasks and awards keeping momentum up. Teachers get a separate set of levers: AI homework grading that routes students back to their own mistakes, class progress summaries that flag who is sprinting and who needs extra attention, and context-aware hints that search your lecture videos, slides, and write-ups when a student stalls on a question. Strength, interest, and personality profiling rounds out the mentoring angle. Compared with Photomath or plain answer solvers, Mathos is closer to an interactive tutor with a teacher dashboard; compared with Wolfram Alpha, it trades symbolic horsepower for pedagogy and classroom workflow.
Behind the Verdict
We'd reach for Mathos when the problem is engagement, not computation. A student who stares at a worksheet and gives up is exactly the case this tool is shaped for: snap the problem, get a hint, get asked a question back, keep moving. The knowledge graph is the part that earns its keep over a semester, because it turns scattered practice into a map of what's actually missing. In practice, the teacher workflows are the reason a school would standardize on it. Grading homework by hand and then trying to remember who struggled with which skill is the bottleneck Mathos attacks, and searching your own lecture videos and slides from inside a student's stuck moment is a genuinely unusual capability. Two cautions. First, this is K-12 territory, starting roughly at middle school and running through high school math; if you're looking for linear algebra, real analysis, or heavy symbolic work, the tool is aimed elsewhere and a computer algebra system will serve you better. Second, pricing is the open question. The vendor pricing page wasn't retrievable on this pass and the site we can read documents only a free entry point, so we're keeping the tier list to what's confirmed and not guessing at seat costs — if you're a department chair budgeting for a rollout, get a quote directly before you commit. On fit: if you want an individual tutor for a self-motivated adult learner, this is heavier than you need. If you run a classroom or a small tutoring practice and want grading plus per-student progress visibility, the combination is hard to assemble from separate tools.

Models Under the Hood
as of 2026-09-23
Limitations
- Mathos is designed around K-12 math tutoring; the site does not describe support for advanced college or graduate-level topics.
- The homepage advertises a beta "Advanced Model" claiming 20%+ higher accuracy than GPT-4, but the underlying model name is not disclosed.
- It runs on the Web, Apple App Store, and Google Play, with no desktop app mentioned and no API documented on the site.

Switching to or from Mathos
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Photomath: manually start using Mathos's Snap & Ask; you'll need to set up your profile and begin tracking progress fresh.
- →From other answer-only solvers: switch your habit to using Mathos's step-by-step and knowledge graph features for deeper learning.
- ↗To Photomath: export nothing—Mathos doesn't integrate, so just start using Photomath for quick answers.
- ↗To a human tutor: cancel any subscription and use your knowledge graph printouts to show your tutor exactly where you struggle.
