Gauth: AI Study Companion

What it is

Gauth: AI Study Companion is an education app from GauthTech Pte. Ltd. It is listed as free, rated for Everyone, and first appeared on Google Play on March 31, 2021. The latest update in the data is dated October 22, 2026.

The core idea is simple. You photograph a homework problem, the app picks out the question, and you get a worked answer with explanations. The listing also says the steps come with animated instructions.

What it does well

The ratings are the strongest argument here. Gauth holds 4.79 stars from 2,210,323 ratings, and the app sits at 100,000,000+ installs. Of those ratings, 87.5 percent are five stars and 8.5 percent are four stars. That is a lopsided split in a good direction.

The subject range is wide for a single app. The description names math, biology, physics and chemistry, and the math list goes deep: algebra, functions, geometry, trigonometry, calculus, statistics, matrices and logic. Word problems are listed too.

There is more than the photo scanner. The listing describes an AI live tutor where you ask by voice and see the explanation on a whiteboard. It also mentions a toolbox with reading help, writing help, a focus mode and a calculator, plus access to human experts around the clock. Those are the developer’s claims, so treat them as what the page promises, not as something confirmed here.

Where it falls short

Money is the first question. The app is free to install, but the description refers to Gauth Plus and Gauth AI Pro, which suggests paid levels. The listing text in our data does not give prices or say exactly which features are locked, so check before you rely on it for heavy daily use.

The second point is accuracy. The page says Gauth is faster and more accurate than other homework helpers. That is a marketing claim. The rating data cannot prove it, and nothing in the listing explains how answers are checked.

Finally, 1.8 percent of ratings are one star and 0.5 percent are two stars. Small numbers, but with over two million ratings they still represent a lot of people who were not happy.

Who it suits

Students who want step by step working on math and science problems, and who like the idea of scanning a page instead of typing a question, are the obvious audience. If you only want an answer without understanding it, the listing’s own focus on explanations suggests that is not the intended use. Parents should note the Everyone content rating, and that the listing does not describe any account requirement either way.
