Gauth is a homework-help app. A student snaps or pastes a question in math, science or other subjects and gets an AI answer with steps and explanations; harder questions can go to paid human tutors who reply in minutes. Newer features include an assignment solver and Atlas, which turns a topic into visual explainers. In the US the terms name TikTok USDS Joint Venture LLC as the operator, and its legal pages are hosted on TikTok's servers.
Our take: Popular with teens for quick answers, which is the problem; families who care about learning the steps should look elsewhere.

Data and privacy
Gauth collects prompts, uploaded files and voice recordings and uses data to train its machine learning models. It says it does not sell data or share it for cross-context ads where the law restricts this, and is not for under-13s. Read the privacy policy.
Does it work?
The maker's own claims only (50k verified experts, 98.5% satisfaction). No independent study was found; a 2025 PNAS study warns that leaning on AI answers can hurt later test scores.
