Mathos AI is a YC W24-backed AI math solver and tutor, founded in 2023 as MathGPTPro, that Forbes reports serves roughly 700,000 monthly users. It solves photographed, typed, voice, or PDF-submitted problems step by step across algebra through calculus, physics and chemistry, in 21 languages, on web, iOS, and Android.
About Mathos AI
Mathos AI, founded in 2023 by Tianwei Yue and Qi Lyu as MathGPTPro before rebranding, is an AI math solver and personalized tutor built for K-12 through college students. The YC Winter 2024 company's own marketing states its AI model scores roughly 20% higher accuracy on mathematical and quantitative problem-solving than GPT-4o, a claim published on Mathos's own site rather than confirmed by an independent benchmark. Forbes reported the app has about 700,000 monthly users as of 2026, while Mathos's own pages separately claim figures ranging from 1 million to 5 million students served; those higher counts are self-published and not independently corroborated. Students hand it a problem through a snapped photo, a typed line, a spoken prompt, or an uploaded PDF, and the app answers with a full step-by-step walkthrough instead of just a final number. Three education modes are offered: full worked steps for a hard problem, a quick answer for a simple one, or an interactive tutor mode that withholds the result and instead prompts the student toward it, positioning Mathos closer to a tutor than a straight answer-key scanner like Photomath. The Basic and Prime plans split solving into two accuracy tiers, MathosPro and MathosMax. Prime removes the daily cap on MathosMax and unlocks a high-quota PDF homework helper that solves an entire uploaded problem set in one pass. The product covers algebra, geometry, calculus, trigonometry and linear algebra, plus physics, chemistry and some humanities subjects, in 21 languages, and independent reviewers note it is stronger at showing algebraic working than at formal proof-level rigor. Pricing spans four tiers: a free plan, two weekly-billed paid subscriptions (Basic and the higher Prime tier, labeled Best Value), and a custom-quoted Enterprise plan with SSO and roster sync for schools; see price_notes for exact figures. Paid tiers carry a short free trial with cancel-anytime billing. The team has drawn some outside recognition (SXSW EDU 2025 Launch finalist, Forbes 30 Under 30 Education, an iF Design award) and has raised funding according to its Forbes profile, though other trackers cite different totals. No SOC 2, GDPR or ISO 27001 attestation is published on its privacy or legal pages as of this research, which limits its fit for school-district-level procurement despite the Enterprise tier's admin tooling.
Pricing
Free plan: $0, no card required. Basic: $5.98/week (about $26/month). Prime: $9.98/week (about $43/month), labeled Best Value, removes the MathosMax daily cap and adds a 20x PDF Helper quota. Enterprise: custom quote-only pricing with SSO and roster sync. All paid tiers include a 3-day free trial and cancel anytime.
Key Features
- Four Ways to Submit a Problem: Accepts a snapped photo, a handwritten scan, a typed equation, a spoken question, or a homework PDF as input, then returns a step-by-step solution across algebra, calculus, physics and chemistry.
- MathosPro and MathosMax Solving Modes: The Basic plan runs unlimited MathosPro queries plus 100 MathosMax (the vendor's higher-accuracy mode) queries per day; Prime removes the MathosMax daily cap entirely.
- Three-Mode Education Engine: A problem can be solved as full worked steps, a quick final answer, or an interactive Socratic-style tutor mode that withholds the answer until the student works through it.
- Built-in Graphing Calculator: An integrated calculator auto-draws graphs for functions and equations directly from a solved problem, without exporting to a separate graphing tool.
- PDF Homework Helper: The Prime tier includes a 20x-quota PDF helper that extracts and solves every problem in an uploaded homework PDF in a single pass.
- 21-Language Support: The solver and tutor interface support 21 languages, so the same step-by-step explanation reaches students without a separate localized product.
Pros
- Free tier requires no credit card and covers unlimited MathosPro (standard-accuracy) solving, letting a student trial the core solver before hitting any paywall.
- Prime removes the daily cap on MathosMax, the vendor's higher-accuracy solving mode, unlocking full-quota PDF and voice input not available on Basic.
- Ships native apps for iPhone and Android in addition to the web version, syncing problem history to whichever device is opened next.
Cons
- The company's own support guidance tells users to double-check MathosMax output, an acknowledgment that accuracy still varies by problem difficulty rather than being guaranteed.
- The newer 'Mathos AI: Smart Solve' App Store listing (separate from the long-running Google Play app) carries only 5 ratings at 1.0 stars, with complaints citing billing and functionality bugs; too few reviews to be conclusive, but a signal the newer app build has rough edges.
- No published SOC 2, GDPR, or ISO 27001 attestation on the vendor's privacy or legal pages, unlike enterprise-oriented study tools such as Edexia, which limits it for school-district procurement despite the Enterprise tier's SSO and roster-sync features.
Frequently Asked Questions
What does Mathos AI cost in 2026?
Mathos AI runs a $0 free tier, a Basic plan at $5.98/week (about $26/month) with unlimited MathosPro solving and 100 MathosMax queries a day, and a Prime plan at $9.98/week (about $43/month) that removes the MathosMax cap and adds a 20x PDF Helper quota. Schools pay custom Enterprise pricing for SSO, roster sync and admin controls. All paid tiers include a 3-day free trial and cancel anytime.
Is Mathos AI free to use?
Yes, the Free plan needs no credit card and includes limited MathosPro solving, limited image and video input, flashcards, quizzes and question history. It excludes MathosMax (the higher-accuracy mode), unlimited voice input, and the PDF homework helper, which are reserved for the paid Basic and Prime tiers.
What are the best alternatives to Mathos AI?
Photomath, now owned by Google, is the more scan-and-solve-focused option with a much larger installed base; pick it for a fast answer rather than tutoring. Symbolab shows more formal step-by-step method detail for calculus and leans toward rigor. Wolfram Alpha remains the reference choice when a symbolic-computation or proof-level answer matters more than a conversational tutor.
How does Mathos AI compare to Photomath in 2026?
Photomath is built around scanning a problem and returning the answer fast, backed by more than 100 million downloads and a far larger public review base. Mathos AI instead offers an interactive tutor mode that withholds the final answer to prompt the student's own reasoning, plus a PDF homework helper Photomath does not offer, at the cost of a much smaller public review history.
How do you get started with Mathos AI?
Create a free account at mathos.ai or install the iOS or Android app, then submit a problem by photo, typed text, voice, or PDF upload. The Free plan works immediately with no card required; upgrading to Basic or Prime starts with a 3-day trial before billing begins.
