Mathos
AI math tutor for K-12 students and teachers with photo-based problem solving and knowledge graph tracking
Mathos is a smart pick for K-12 math practice and teaching support, thanks to its photo input and knowledge graph feedback. The free tier is useful, but pricing beyond that is unclear—check current plans before committing. Not for advanced college math.

About Mathos
Mathos is an AI math tutor designed for K-12 students and teachers. Snap a photo of a math problem and get instant step-by-step guidance, or engage with interactive tutoring that uses socratic questioning and hints to encourage understanding. The platform tracks each student's progress with a knowledge graph profile, identifies strengths and weaknesses, and recommends personalized practice problems. Already used for over 50 million questions across 200+ countries, Mathos is available on web, iOS, and Android. For teachers, it automates homework grading, summarizes class progress, and pulls relevant concepts from lecture videos, slides, and write-ups—so students get context-aware hints and no one falls behind. Its beta math model reports 20%+ higher accuracy than GPT-4 on math tasks. Mathos sits apart from simple answer-only solvers by focusing on progressive, personalized learning—helping students think critically and helping teachers scale one-on-one attention.
Behind the Verdict
Mathos stands out in the crowded AI math tutor space by focusing on progressive, personalized learning rather than just answer generation. The photo-based input is a major convenience for students who are stuck on homework problems—snap, get step-by-step guidance, and learn the concept. The knowledge graph tracking is a differentiator: it doesn't just give answers; it builds a profile of what you know and don't know, then recommends problems that target your gaps. This is genuinely useful for long-term mastery. For teachers, the automation of grading and class progress summaries is a time-saver. The integration with lecture videos and slides for hints is a thoughtful feature that connects AI tutoring directly to classroom materials. However, Mathos is explicitly K-12 focused. If you're tackling college-level calculus or graduate math, this isn't the tool. Also, the free tier may include ads according to seed data, and pricing details beyond the free tier are not clearly documented—a potential drawback for schools or districts that need budget clarity. The beta model claims 20%+ higher accuracy than GPT-4 on math tasks, which is impressive if true, but the underlying model name isn't disclosed, making it hard to verify or compare with competitors. Overall, Mathos is a strong choice for K-12 students and teachers who want a guided, personalized learning experience. It's not for those who want quick answers without explanation or who need advanced math support.
