Gauth AI Review 2026: Features, Pricing & Alternatives

Last updated: February 2026

Take a photo of a math problem, get a step-by-step solution in seconds. That is Gauth (formerly Gauthmath), an AI homework helper owned by ByteDance. It covers 30+ subjects across 50+ languages, with a ~95% solve rate for typical K-12 and college STEM questions. 4.9/5 on the App Store from 1.67M+ reviews.

The obvious question: is this cheating? That depends entirely on how students use it. As a learning tool that explains the steps, it is genuinely helpful. As a copy-paste answer machine, it undermines education. Gauth provides the tool. The responsibility sits with the student.

How It Works

Snap a photo of a printed or handwritten problem (or type it), and Gauth's AI returns a step-by-step solution. The explanations break down the reasoning at each step, not just the final answer. Follow-up questions are supported through conversational AI chat, so students can ask "why did you factor this way?" or "what if the variable was negative?"

Subject coverage goes well beyond math: physics, chemistry, biology, coding, writing, economics, social sciences, and SAT prep. The platform has 100M+ previously solved questions that Premium users can search directly.

Live Tutors and Browser Extension

When AI cannot solve a problem (complex proofs, unusual problem types), live human tutors respond within 5-10 minutes on the Tutor plan. This hybrid approach fills the gap that pure AI tools leave open.

A browser extension brings Gauth to desktop, useful for students working on laptops who do not want to pull out their phone for every question. A homework planner with progress tracking helps students organize assignments.

Pricing

Free: Limited daily solutions. Core features accessible. 100% ad-free.
Premium (~$9.99/month): Unlimited AI solutions, AI tutor guidance, access to 100M+ solved questions.
Tutor (~$19.99/month): Everything in Premium plus live human tutor support for problems AI cannot handle.

Annual pricing is approximately $99.99/year. Pricing may vary by region and platform. Both the free and paid versions are completely ad-free, which is notable for an education app.

What Students Like

Instant answers: Photo-to-solution in seconds. No waiting for a tutor's availability.
Step-by-step explanations: Not just answers. The breakdown helps students understand the methodology.
Math accuracy: ~95% solve rate for standard K-12 and college STEM. Algebra, calculus, statistics, and physics are strong areas.
Ad-free: No ads on any plan, including free. Rare for education apps.
Multi-subject: Goes beyond math into science, coding, writing, economics. One app for most homework.
Conversational follow-ups: Ask clarifying questions about the solution. Feels like tutoring, not just answer lookup.

Where It Falls Short

Advanced math struggles: Complex calculus proofs, advanced graphing, and non-standard problem formats have lower accuracy.
Humanities are weak: Essay writing, literary analysis, and subjective questions produce generic responses. This is primarily a STEM tool.
Handwriting OCR issues: Messy handwriting causes recognition failures. Students need to write clearly or type the problem instead.
Academic integrity risk: The tool makes it trivially easy to copy answers without understanding them. Schools are increasingly flagging Gauth-style tools.
Dependency concern: Regular use without engaging with the explanations can create a crutch that hurts learning long-term.

Our Take

Gauth is the best AI homework helper available, particularly for math and STEM. The photo-to-solution workflow is fast, the step-by-step explanations are clear, and the ad-free experience is refreshing. The ~$10/month Premium price is reasonable for students who use it daily. The academic integrity concern is real but not Gauth's problem to solve. Parents and educators should set expectations around how the tool is used. For students who engage with the explanations rather than just copying answers, Gauth is a genuinely effective study tool that is available 24/7 for the price of a fast food meal.
