Gauth Review: Features, Pricing & Alternatives
AI homework helper that solves photographed problems step by step, with optional live tutors.
What is Gauth?
Gauth is an AI homework helper for high school and college students. You take a photo of a problem or type it in, and Gauth returns an answer with step-by-step working. It started with math but now covers chemistry, physics, biology, economics and writing, on the web, iOS, Android and a browser extension.
The app launched in 2020 under the name Gauthmath and is now published by Gauthtech Pte. Ltd., a Singapore company. Axios reported in 2024 that Gauth is owned by ByteDance, the parent company of TikTok, and that it had reached the top three free education apps in US app stores. Its terms require users to be at least 13.
In 2025 and 2026 Gauth added more study features around the core solver. The App Store listing now describes an AI Live Tutor with voice and a whiteboard, a DeepThinking mode for harder concepts, a Smart Study Converter that turns notes into quizzes and flashcards, and a visual learning tool called Gauth Atlas. Its mix of instant AI answers and paid human experts sets it apart from general chatbots.

Gauth vs alternatives
Photomath is the closest rival for math: it focuses on step-by-step math solutions with animated explanations, while Gauth covers more subjects and adds human experts. Brainly combines AI answers with a large community Q&A library and paid live tutors.
For guided learning that avoids handing over answers, Khanmigo asks Socratic questions instead of solving the task. General chatbots such as ChatGPT and Gemini can also explain problems, but they are not built around homework photo scanning. See all best AI education tools.
Our verdict: is Gauth worth it?
