Overview
Gauth (formerly Gauthmath) is an AI-powered homework helper developed by ByteDance (the company behind TikTok and Douyin). Students photograph math problems, and Gauth's AI provides step-by-step solutions with explanations. The app has expanded beyond math to cover science, history, literature, and other subjects, making it one of the most comprehensive AI homework assistance platforms available to students globally.
Gauth's core strength is accessibility and breadth — it handles virtually any school subject through its combination of AI solvers and a community of expert tutors who can answer questions that AI struggles with. The platform is particularly popular in Asia and has grown a substantial global user base. Its integration with ByteDance's technology stack gives it advantages in visual recognition (reading handwritten problems) and multimodal understanding.
In 2026, Gauth has significantly improved its AI capabilities, with better step-by-step explanations and expanded subject coverage. The platform's photo-to-solution feature works with printed textbook problems, handwritten work, and digital assignments across multiple languages.

How It Compares
Gauth vs Photomath
Photomath is math-only with excellent step-by-step. Gauth covers more subjects and has human tutor backup, but math quality is similar between the two.
Gauth vs Synthesis Tutor

Final Verdict
Our Recommendation
Gauth is one of the most practical and accessible AI homework helpers available, particularly for students who need multi-subject support. The combination of AI solving, step-by-step explanations, and human tutor backup creates a reliable resource for most homework challenges. For students who use it to learn from examples and check their understanding, Gauth is genuinely valuable. The main concern is academic integrity — it's easy to misuse, and educators have mixed views on its role in learning. Used responsibly, it's an excellent tool; used as a shortcut, it undermines learning.
