Gauth: AI Study Companion for Android

Gauth: AI Study Companion is an education app by GauthTech Pte. Ltd. that provides AI-powered homework help and step-by-step explanations across multiple subjects. Launched in March 2021 and updated to version 2.10.0 in September 2026, the app has grown into a widely used tool with over 100 million installs and a 4.79 rating from more than 2.1 million reviews. It positions itself as a comprehensive alternative to traditional tutoring, combining photo-based problem recognition, an AI live tutor, and access to human experts around the clock. The core workflow is straightforward: you snap a picture of a question, the app crops and recognizes it, then returns a formatted solution with animated instructions and detailed explanations within seconds. This makes it particularly useful for students who need quick clarifications on math, physics, chemistry, biology, and other topics without waiting for office hours or forum replies. The latest version, 2.10.0, includes small optimizations aimed at smoothing the user experience rather than introducing headline features, so existing users can expect refinements to speed and interface polish. Beyond the basic solver, the app bundles a study toolbox with reading assistance, writing support, focus mode, and a calculator, effectively consolidating several study aids into one package. It also offers Gauth Plus, a paid tier that unlocks unlimited answers, higher accuracy, access to over 20 million tutorial videos, and a question bank of more than 100 million items, alongside 24/7 tutor availability. For experienced users comparing alternatives, the key differentiator is the blend of AI speed and human expert backup, though the app does request a fairly broad set of permissions including camera, microphone, storage, and calendar access, which is worth reviewing before installation.

The latest update to Gauth: AI Study Companion (version 2.10.0) brings a series of small refinements aimed at making the app smoother and more intuitive to use. These tweaks focus on optimizing the overall user experience, so you can get the help you need with even less friction. Jump in today to see what's changed and enjoy a more polished study session.

This app suits high school and college students tackling math, science, and other homework subjects, as well as self-learners who want immediate explanations without waiting for a tutor. It also appeals to parents seeking a supplemental homework aid for their children, and to adult learners refreshing their knowledge in STEM fields who value both AI speed and human expert backup.

For best results, frame the question clearly in the photo and ensure good lighting; if the initial recognition fails, crop the image manually to isolate the problem before resubmitting, as this often improves accuracy and reduces the need for follow-up clarifications.

Gauth: AI Study Companion is a robust and well-regarded homework solver that effectively merges AI speed with human expertise, covering a wide array of subjects and offering a handy all-in-one toolbox. The broad permission requests and the push toward a paid tier are the main caveats, but for experienced users seeking a reliable, fast, and comprehensive study aid, it remains a strong choice, especially if you are comfortable with its privacy trade-offs and willing to consider the premium upgrade for unlimited use.
