Gauth
ByteDance's AI study companion: photo a problem, get steps.
About
Gauth (formerly Gauthmath) is ByteDance's AI study companion: photograph a homework problem and get step-by-step solutions in seconds, across math, physics, chemistry, and biology. It pairs the AI solver with 24/7 human tutors, a 100M+ question bank, and a study toolbox with reading, writing, and calculator aids. It holds a 4.9/5 App Store rating across 1.6M+ reviews.
The free tier is tight (about 3 questions a day), Gauth Plus at $11.99/month is among the pricier solver subscriptions, and accuracy dips on college-level calculus. US users should also know it sits under the same ByteDance scrutiny as TikTok.
