Overview

What is Mathos AI?

Mathos AI — formerly MathGPTPro, and still served from mathgptpro.com — is a mathematics learning platform published by MetaDigits.AI, Inc. in San Francisco. It brings together three products the company calls pillars, with an adaptive engine underneath them.

The Math Solver accepts a problem in any form: a photo of a worksheet, a PDF, typed text or spoken words. It breaks the problem down to its core and re-explains until it lands, and you decide how much help to take — a single nudge, or the full worked solution in typeset notation with every step stated and justified. Two engines sit behind it and can be switched per question: MathosPro for fast everyday work, MathosMax when accuracy matters most. Graphs are drawn automatically alongside the algebra.

Video Generation turns any problem or solution into a narrated, animated explainer. The publisher claims a first frame in five to ten seconds, and its April 2026 changelog puts a complete second-generation video at fifteen seconds. Every artefact stays editable.

The AI Tutor is positioned as the opposite of a chatbot you query: it watches the learner work on a whiteboard and steps in at the exact point where reasoning breaks, rather than after the final answer. Each session ends with a report on where the student struggled and what to practise next, and a parent dashboard tracks mastery, pace and progress.

Beneath all three, the Adaptive Learning engine claims to read the reason behind a wrong answer, repair the missing prerequisite and return the learner to the frontier, instead of simply serving an easier version of the same topic.

Coverage runs from arithmetic, fractions and pre-algebra through algebra, geometry and trigonometry to precalculus, calculus, multivariable calculus, linear algebra and differential equations, with statistics and physics handled too. Companion tools include a graphing calculator, Quiz Me, a PDF homework helper, an AI whiteboard and more than a thousand topic-specific calculators.

The company reports over five million students and more than a hundred million problems solved, and carries Y Combinator (Winter 2024), Forbes 30 Under 30, an SXSW EDU 2025 finalist place and an iF Design Award 2026. Mathos AI runs on the web, iOS and Android, declares eighteen interface languages, and also sells its engines to schools and to other platforms through an API.

What it does

  • Solve a maths problem step by step from a photo, a PDF, typed text or your voice
  • Ask for a single hint instead of the whole solution, and keep working the problem yourself
  • Switch between MathosPro for speed and MathosMax for best accuracy, question by question
  • Turn any solution into a narrated explainer video, a quiz, a flashcard deck or a game
  • Get graphs drawn automatically alongside the algebra
  • Work on the AI whiteboard while the tutor follows each step and corrects the moment you slip
  • Read a per-session report and follow mastery over time from the parent dashboard

Trust & Privacy

Data, GDPR & hosting

A consolidated view of how Mathos AI handles your data.

GDPR overview

The privacy notice, last updated 28 December 2025, is a Termly-generated document with a real GDPR section rather than a passing mention. It sets out the legal bases relied on — consent, legitimate interests, legal obligations and vital interests — and grants EEA, UK, Swiss and Canadian users access, rectification, erasure, restriction, portability, objection and freedom from automated decision-making, with links to the relevant supervisory authorities. Rights are exercised through a Termly data subject access request or by emailing support@mathos.ai. Two gaps matter: no EU representative is designated under Article 27, although the publisher is established in the United States, and no data protection officer is named. There is no DPA, no published subprocessor list, no mention of standard contractual clauses and no security certification such as SOC 2 or ISO 27001.

Who owns the data?

The terms are explicit that you keep your content: MetaDigits.AI, Inc. asserts no ownership over your Contributions, and you retain full ownership and any associated intellectual property rights. The licence you grant alongside that sentence is far broader than it suggests — unrestricted, unlimited, irrevocable, perpetual, non-exclusive, transferable, royalty-free, worldwide and sub-licensable, covering hosting, reproduction, resale, publication, translation and distribution for any purpose, commercial or advertising included, with a waiver of moral rights. Separately, the terms state that the publisher keeps certain data you transmit in order to manage service performance, and accepts no liability for its loss or corruption. Payment data is held by Stripe and RevenueCat rather than by Mathos AI.

Reuse rights

Nothing in the terms restricts what you do with the solutions, videos, quizzes or flashcards Mathos AI produces for you: no separate output licence is imposed and no attribution is required, so you may reuse them for your own study without asking permission. The limits are contractual rather than about the content itself. Access is granted for personal, non-commercial use only, and using the service for any revenue-generating endeavour, or to compete with the publisher, is listed as a prohibited activity. Systematically retrieving content to build a collection, compilation or database, and any scraping or automated extraction, are also forbidden without written permission. On the publisher's own side, your inputs and outputs are shared with third-party AI service providers, OpenAI named among them, and the privacy notice states that no personal information has been sold or shared in the past twelve months and that none will be in future.

Data retention & training

Retention summary
Mathos AI keeps personal information only for as long as it needs it for the purposes set out in its privacy notice, unless a longer period is required or permitted by law for tax or accounting reasons. The publisher sets one ceiling: no purpose requires keeping personal information beyond the period during which you hold an account, and the US state privacy table repeats that rule for every category collected. When you ask for your account to be closed it is deactivated or deleted from the active databases, though some information may be kept to prevent fraud, troubleshoot problems, support investigations, enforce the terms or comply with the law. Where deletion is impossible because data sits in backup archives, the notice says it is stored securely and isolated from further processing until deletion becomes possible. No retention period is stated in days or months.
GDPR contact

Hosting summary

Mathos AI publishes nothing about where user data is hosted. Neither the privacy notice, the terms of service nor any security or trust page names a hosting country, a region or a cloud provider, and no data processing agreement or subprocessor list is offered. The only jurisdictional anchor is the publisher itself: MetaDigits.AI, Inc. is registered in California and operates from San Francisco, and the terms are governed by California law. A few processing locations can be guessed at from the third parties the privacy notice names — payment data is handled and stored by Stripe and RevenueCat, AI processing is carried out by third-party providers with OpenAI named, and Google Analytics is used — but the notice never says where any of them process. One purely technical signal, which is not a statement by the publisher, is that the domain resolves to an Amazon Web Services address geolocated in the United States. Anyone with a data residency requirement should treat the hosting jurisdiction as undeclared and ask the publisher directly.

Watch-outs

Things to keep in mind

Risks and trade-offs to weigh before adopting Mathos AI.

  • Copying the answer is easier than reading the reasoning: the tool can quietly replace the work it exists to support
  • Leaning on a solver for every exercise erodes tolerance for being stuck, which is where most mathematical learning happens
  • Weekly billing disguises the annual cost, and subscriptions renew automatically unless cancelled at least 24 hours ahead
  • Subscriptions bought through the App Store or Google Play must be cancelled at the store, not with the publisher
  • Inputs and outputs are passed to third-party AI providers, with no documented way to exclude them from model training
  • A third-party advertising offer wall can appear in the app, sharing a user identifier with the advertiser
  • The publisher warns that Mathos can make mistakes and asks users to cross-validate crucial steps: a confidently wrong solution taken into an exam is a real risk
Setup

Setup & Integrations

Technical difficulty

Very low for an individual. The web app opens at mathgptpro.com/app/ask with nothing to install, the free plan needs no payment card, and sign-up is by email or a social login. A short onboarding asks for your study level so explanations are pitched correctly. Mobile users install the iOS or Android app from the download page. Effort rises sharply at organisation level: SSO, roster sync and API access to the Solve, Video and Adaptive engines are integration projects, and each of them runs through a sales contact rather than self-service.

FAQ

Frequently asked questions

Is the free plan genuinely free?
Yes. The Free plan covers step-by-step solving, auto-drawn graphs, flashcards, quizzes and your question history at no cost, and no payment card is required. Paying buys unlimited solving, the highest-accuracy engine and a larger video quota.
What can I send Mathos AI, and which subjects does it cover?
You can snap a photo, upload a PDF, type or speak a problem. Coverage runs from arithmetic, fractions and pre-algebra through algebra, geometry and trigonometry to precalculus, calculus, multivariable calculus, linear algebra and differential equations, with statistics and physics also handled.
How much does the cheapest paid plan cost?
Basic is displayed at USD 2.99 per week against a struck-through USD 5.98, and Prime at USD 4.99 against USD 9.98. Payments are taken in US dollars. An annual option is advertised at 80% off, though no annual figure is published on the pricing page.
How does the free trial work, and can I cancel?
Paid plans open with a three-day free trial where eligible, and the terms mention three or seven days depending on the offer. You can cancel at any time, including during the trial, but you must cancel at least 24 hours before a renewal to avoid being charged.
What is the difference between Basic and Prime?
Basic gives unlimited MathosPro solving, 100 MathosMax solves a day and double the video quota. Prime unlocks unlimited MathosMax, five times the video quota, twenty times the PDF Helper quota, unlimited voice input and no limits on the advanced models.
Are there mobile apps?
Yes. Mathos AI runs on the web and ships iOS and Android apps, both linked from its download page. Note that the iOS listing appears under a different product name, MathTube: All-in-One Calculator.
Who owns what I submit, and where does my data go?
You retain full ownership of your contributions, but the terms take a very broad perpetual, transferable and sub-licensable licence over them. Your inputs and outputs are shared with third-party AI providers, OpenAI named among them, and payment data is held by Stripe and RevenueCat.
Is there an API?
In principle, yes. The publisher sells its Solve, Video and Adaptive engines to platforms, and offers schools SSO, roster sync and usage analytics. There is no public API documentation, however: access goes through a sales contact form.
Is there a minimum age?
No minimum age is published. The terms require anyone who is a minor in their own jurisdiction, generally under 18, to have a parent or guardian's permission and to be directly supervised by them.
How long is my data kept, and can I have it deleted?
The notice says information is kept no longer than the period during which you hold an account, without stating any figure in days or months. You can request deletion through the Termly data subject access request form or by emailing support@mathos.ai, though some records may be kept for fraud prevention and legal compliance.
Conclusion

Should you pick Mathos AI?

Mathos AI is a mature, visibly maintained product in a crowded niche. What sets it apart from a plain answer engine is the intent in its design: the tutor steps in where reasoning breaks rather than after the final answer, and the adaptive engine claims to repair the missing prerequisite instead of serving an easier version of the same topic. Whether it delivers on that is not something a reading of the site can settle — the accuracy claims it advertises, 20% better than ChatGPT in maths and mastery 40% faster, come with no published protocol or benchmark.

The commercial offer is genuinely generous at the entry point: a permanent free plan with step-by-step solving, graphs, flashcards and quizzes, no payment card, and a paid tier at USD 2.99 a week. That weekly framing is the thing to watch. It reads as small and lands near USD 155 a year, and the price is presented as a discount on a struck-through rate with no stated end date.

The weak point is data governance rather than the product itself. There is no DPA, no published subprocessor list, no EU Article 27 representative despite a US publisher serving European users, no stated hosting jurisdiction, and nothing at all on whether customer data trains models. Two identity inconsistencies also deserve a note: the terms name MetaDigits.AI, Inc. while the site's structured data names Mathos, Inc., and the iOS app is listed under a different product name.

For students, parents, tutors and maths teachers who want worked reasoning rather than a copied answer, it is a credible and inexpensive option, and the free plan makes it cheap to test. Schools and any buyer with a procurement checklist should press the publisher on the compliance gaps first.
