Gauth AI: photo-scanned homework help from ByteDance, tutors on standby
Updated on September 6, 2026
Gauth AI is an AI homework helper that solves a photographed exercise and explains the reasoning line by line. ByteDance, the company behind TikTok, sits behind it. Rated 4.9/5 on the App Store across over 1.6 million reviews, the app covers around 30 subjects, from algebra to essay writing. A free plan with a daily cap gets you started, and Gauth Plus lifts the ceiling for heavy study sessions.
Pros
- Worked solutions seconds after the photo
- Around 30 subjects, essays and coding included
- Human tutors on call around the clock
- Reads messy handwriting and full PDFs
Cons
- Tight daily cap on free questions
- Accuracy dips on college-level calculus
- Cancellation smoother through app stores than in-app
Snap the problem, walk through every step
You frame the exercise with your phone camera, handwritten or printed, and a step-by-step solution lands within seconds. The optical character recognition deciphers rushed handwriting too, as long as the lighting cooperates.
The chat keeps going after the answer. Ask why it factored that way, or what happens with a negative variable, without retyping a thing. And when the AI stalls on a stubborn problem, roughly 5% of cases according to the company, a human tutor takes over, day or night.
| Input | Typical example | What comes back |
|---|---|---|
| Photo | Handwritten equation in a notebook | Full solution, step by step |
| Typed question | Multiple-choice chemistry problem | Explained answer with follow-up chat |
| An entire worksheet | Corrections for the whole page | |
| YouTube link | A two-hour lecture | Transcript, summary and a revision quiz |
Hands-on Gauth AI review, pricing and honest verdict
From Gauthmath to Gauth AI, ByteDance's homework play
ByteDance, TikTok's parent company, runs the app. Born as a math solver called Gauthmath, it changed scale in 2024 with an in-house engine, Gauth GPT, and around 30 subjects on the menu, physics, chemistry, biology, economics, writing and SAT prep.
The numbers are hefty. Over 50 million Android installs, repeated first places on US education download charts, and an App Store rating close to a perfect score. It also answers in 50+ languages, a breadth that few AI study companions for students can claim.
Free plan, Gauth Plus and human tutors on call
The free account caps you at a handful of questions per day, ads included, with a three-day trial to size up the paid tier. Gauth Plus runs $11.99 per month after a $9.99 first month, or $99.99 per year, and a Tutor plan around $19.99 per month adds priority access to human experts.
One practical tip (Trustpilot reviewers are blunt about this), manage auto-renewal from the App Store or Google Play rather than inside the app. These amounts shift by country and platform, so the grid on the official site is the one to trust.
- Unlimited questions, ad-free experience
- A bank of 100M+ already-solved problems
- Priority help from human tutors
Frequently asked questions
Is Gauth AI free?
Partly, yes. The download costs nothing and a small daily allowance of questions comes with ads. A three-day trial then opens everything up, after which Gauth Plus removes the caps and the ads for students with heavy homework loads.
Gauth AI or Photomath, which one should you pick?
Photomath sticks to math and polishes its animated explanations beautifully. Gauth AI spreads much wider, physics, chemistry, biology, writing, and keeps human tutors in reserve. For a student juggling several subjects at once, that broader coverage tips the scale toward Gauth AI.
Who owns Gauth AI?
ByteDance, the Chinese group behind TikTok, owns Gauth AI through GauthTech Pte. Ltd. The app was briefly pulled in the United States in January 2025 during the short-lived TikTok ban, then came back online a few days later.
How do you cancel a Gauth AI subscription?
Go through the platform where you subscribed, iOS subscription settings on Apple devices, Google Play subscription management on Android, at least 24 hours before renewal. Plans renew automatically and started periods are not refunded, so a little anticipation saves real money.
Verdict: A problem set stuck at 10 pm comes unstuck with one photo. Middle schoolers, high schoolers, college students and parents drafted into evening tutoring duty all gain a pocket tutor, with human experts backing up the toughest chapters.
