Gauth Review, Pricing & Alternatives (2026)
Photo-first AI study help with step-by-step answers and expert support.
Last updated: October 26, 2026
What is Gauth?
Gauth is ByteDance’s photo-first study service, formerly Gauthmath, offering step-by-step help across mathematics, science, writing, and other subjects, with optional expert support. A Free Plan provides limited access and 100 daily assignment-solver credits. Gauth PLUS costs $11.99 monthly, $31.99 quarterly, or $99.99 annually in the US App Store, with regional variation.

Gauth began as Gauthmath and launched in 2020, after an expert sought to help students facing difficult problems. The service was upgraded from Gauthmath to Gauth in 2024 as its scope expanded beyond mathematics. ByteDance owns the company, and Gauth says its service has surpassed 200 million downloads worldwide. This history explains the product’s current identity: it remains centered on guided problem solving and access to experts, but now presents itself as a broader study platform. Its coverage includes mathematics, science, writing, and other subjects, giving it a wider academic role than the focused mathematics solver associated with its original name. The brand’s photo-first identity remains central to its student-facing experience. That expansion explains why the current product addresses general study tasks rather than retaining its original mathematics-only identity.
Students can photograph a question, upload material, or type a prompt. Gauth provides step-by-step solutions for mathematics, physics, chemistry, and related subjects, then supports follow-up explanations and detailed reasoning. The service also includes an assignment solver, calculator, AI YouTube tools, study resources, courses, writing support, and expert assistance. Its download information says students can reach experts around the clock after submitting a question. The mobile experience adds voice tutoring, a virtual whiteboard, note conversion, quizzes, flashcards, reading and writing tools, and a study timer. This breadth makes Gauth useful across homework tasks, but students should inspect explanations and reasoning rather than submit generated answers without checking them. The distinction between automated explanations and expert assistance matters when deciding how much follow-up a difficult question will need.
Gauth says it uses computer vision and natural-language processing to recognize questions and generate explanations, though it does not publish model names. Its current mobile listing promotes multi-model AI, an AI Live Tutor, DeepThinking, study-material recognition, tutorial videos, and practice questions. The company also describes personalized AI courses, user-generated lessons, an unlimited digital canvas, visual explanations, and more than 200 AI math courses. Together, these features show a product moving beyond image-based answer generation toward guided learning and visual study activities. However, the profile provides no independent accuracy measurements. The named capabilities describe available product features and company announcements, so students should treat output as assistance that still requires academic judgment and review. These features broaden the study workflow, although a vendor description of accuracy should not be mistaken for an independent benchmark.
Gauth uses a freemium model. Its Free Plan provides limited answers, AI queries, Gauth AI Pro solutions, and expert service, plus 100 assignment-solver credits each day. In the US App Store, Gauth PLUS costs $11.99 monthly, $31.99 quarterly, or $99.99 annually. Paid access offers expanded features and detailed explanations, while additional expert opportunities may be available through in-app purchases. Subscriptions renew automatically unless canceled through Apple settings. Prices, features, introductory offers, and availability can differ by country, platform, and account. The free tier therefore works as an entry point, while frequent users may consider paid access after checking the terms shown in their own app or region. For occasional use, the daily free assignment allowance is a more useful starting point than committing immediately to a year of access.
Gauth suits students who want photographed homework help, broad subject coverage, explanations, and optional expert support. Its limits include possible AI mistakes, changing regional subscription details, and privacy concerns when uploaded work contains names, handwriting, or school identifiers. Photomath is a direct rival for photographed mathematics problems, while Socratic offers question-based study help and Wolfram Alpha is stronger for structured computation. ChatGPT provides broader open-ended conversation but is not specialized as a homework app. Students seeking visual assistance across several subjects should pick Gauth. The paid plan therefore needs to earn its cost through repeated use rather than through a single successful photographed problem. Math-only learners may prefer Photomath, and users focused on formal calculations may prefer Wolfram Alpha.
Who is Gauth best for?
- Students who prefer photographing homework.
- Learners seeking explanations across school subjects.
- Users wanting optional expert academic support.
- Families seeking a free starting plan.

Technical Details
Frequently Asked Questions
Is Gauth free?
Yes. Gauth has a Free Plan with limited answers, AI queries, Pro solutions, expert service, and daily assignment-solver credits. Gauth PLUS is paid, and expert opportunities may involve in-app purchases. The US App Store lists monthly, quarterly, and annual prices, while regional prices and introductory offers can differ.
What is Gauth’s closest rival?
Photomath is Gauth’s closest direct rival for photographed mathematics problems and step-by-step explanations. Gauth covers more subjects and adds expert support, courses, writing tools, and broader study features. Photomath is the narrower choice for mathematics-focused work, while Gauth suits students wanting a wider study companion.
How does Gauth handle privacy?
Gauth’s privacy policy concerns information such as registration details, user content, photos, comments, chats, contacts, purchase information, and location access. Homework images can contain names, handwriting, or school identifiers. Review the privacy policy before uploading personal material and avoid including unnecessary identifying details.
Does Gauth train models on user content?
Gauth’s privacy policy does not say whether it trains its AI models on user content. It describes collection of user content and related account information, but that is not the same as a model-training statement. Review the current privacy policy and contact Gauth for a definitive answer about submitted homework.
Can businesses use Gauth commercially?
The public consumer terms and product pages do not establish a broad commercial license for generated answers or automated access. Businesses should not assume that a consumer subscription permits commercial reuse, bulk extraction, or service integration. Written permission or separate business terms should be obtained before commercial deployment.
