Gauth AI Study Companion: Is It Free, Safe & Accurate?

A calculus worksheet, a 9 a.m. deadline, and zero idea where to start. That’s when a lot of students open the Gauth AI study companion, snap a photo, and wait about five seconds for a worked answer.

On the App Store, Gauth sits near 4.9 stars from more than a million ratings. Trustpilot paints a darker picture at 2.3 out of 5. So which one tells the truth?

Both, sort of. Below you’ll find the 2026 prices, the billing trap that drags down those reviews, where the math holds up, and how to use the app without letting it think for you.

What Is Gauth AI?

Gauth AI is a free homework helper that reads a typed or photographed question and explains how to solve it. Paying users get unlimited answers through Gauth Plus.

It started as Gauthmath, a pure math scanner. These days it covers physics, chemistry, biology, and some humanities too, which makes it a homework-focused branch of the wider AI companion trend.

How the Gauth AI Study Companion Works

You capture a question, the AI splits it into numbered stages, and you keep asking follow-ups until it clicks. When the model stalls, a human expert can take over.

A small detail most reviews miss: public solution pages on the website carry a helpfulness score from other students. One algebra answer we pulled up showed 84% from 24 ratings. Anything far below that deserves a second opinion.

Scanner and solver

Point the camera at a printed or handwritten problem. The app crops it, reads it, and lays out a guided walkthrough with short animations. Its App Store page lists topics from basic algebra up to calculus, statistics, and matrices.

Misreads cause some errors, but the bigger issue sits deeper. Photomath and Wolfram Alpha run rule-based math engines that actually calculate. Generative models predict the next token instead, so they can flip a sign or drop a term even after reading the photo perfectly. Gauth hands routine math to an internal solver, one 2026 hands-on review notes, yet long chains still lean on prediction.

Gauth AI Pro and AI Live Tutor

Pro, the stronger engine, blends several models and keeps whichever result fits best. Live Tutor lets you ask out loud while the tutor sketches the answer on a whiteboard, which suits kids who learn by listening.

AI Course video lessons

The newest addition arrived on July 31, 2026. Type a topic and a skill level, and ByteDance’s Seedance 2.5 video model builds a short animated lesson with a mind map and quick questions

Study Converter and flashcards

Feed it lecture notes, photos, audio, or a YouTube link, and out with quizzes and flashcards. Since August, the app also files your wrong answers into review cards automatically.

Focus Mode, a writing helper, and a scientific calculator round things out.

Is Gauth AI Free? Pricing and the Billing Trap

Yes, Gauth is free to download, and the free tier hands out a limited number of answers per day. Gauth Plus lifts that cap, switches on Gauth AI Pro, and removes ads.

Prices match the App Store list and a September 2026 pricing check. Other countries pay different amounts. New accounts usually see a 3-day trial.

Why the Trustpilot score is so low

Math errors aren’t the main grievance. Billing is. On Gauth’s Trustpilot page, two in three reviewers give one star. Some say a charge hit on trial day one. Another kept seeing “a network exception error” every time they tried to stop payments, and one person claims they paid $11.99 a month for over two years.

Skip the in-app subscription menu. End Plus through the store that bills you, at least 24 hours before the trial runs out, and keep the confirmation email.

• iPhone: Settings → your name → Subscriptions → Gauth → Cancel Subscription (Apple’s instructions)
• Android: Google Play → profile icon → Payments and subscriptions → Subscriptions → Gauth (Google’s instructions)
• Website: stop it in account settings, screenshot the result, and dispute any later charge with your card issuer

Is Plus worth the money?

Hit the free cap three days in a single week? The yearly plan probably pays for itself. Need help twice a month? Stay free.

Gauth App Download for iPhone, Android and PC

The official app lives on the App Store and Google Play, and the website works in any browser. Setup takes a couple of minutes either way.

• iPhone and iPad: search “Gauth: AI Study Companion,” make sure the seller reads GauthTech Pte. Ltd., then tap Get. It needs iOS 13 or newer and about 96 MB.
• Android: grab the GauthTech listing on Google Play. Allow camera access when you scan your first problem, not before.
• PC, Mac, or Chromebook: there’s no desktop app. The browser version takes typed questions, uploads, and pasted screenshots. Gauth has also offered a Chrome extension for clipping questions, though its Web Store listing comes and goes, so confirm the publisher before installing.

Skip APK mirrors and emulator bundles. Store copies get security patches, and store billing keeps refunds on the table.

Is Gauth AI Accurate?

Gauth handles routine K–12 math and science well, and it slips on long, unusual or college-level problems. Nobody publishes an independent per-subject accuracy test, so treat any exact percentage you read online with suspicion.

Here’s the pattern user reports point to:

One failure deserves extra attention. Sometimes the final number comes out right while a line in the middle breaks a real rule. Copy that working into your notes, and you’ve learned a fake method.

Some Trustpilot reviewers also say the app refuses to budge after they point out a mistake. Every chatbot shares that habit, and the AI hallucination problem explains why: models would rather sound sure than admit doubt.

Is Gauth Safe for Students?

Gauth is a real, legitimate product, but it gathers personal data, and some schools block it. Parents should weigh both before a kid signs up.

The data question

Apple’s privacy label lists contact info, user content, identifiers, usage data, and diagnostics. Identifiers can also follow users across other companies’ apps. With a Chinese parent firm in the picture, data jurisdiction is the worry many districts raise. A fresh email address and a quick read of the privacy policy cut the exposure.

School rules and AI detectors

For schools, this goes beyond personal privacy. Districts must meet student-privacy laws such as FERPA and COPPA before approving any app, and many block ByteDance software on school Wi-Fi and devices as a result. Teachers set their own lines too, and academic integrity rules still differ from one campus to the next. Homework help usually passes. Opening the app mid-test usually doesn’t.

Writing tools carry a separate risk. Paste a Gauth paragraph into an essay, and detection software may flag it. Rewrite ideas in your own voice and keep rough drafts as proof you did the work.

Gauth Alternatives: Solvely, Photomath, ChatGPT and More

Gauth fits best when you need photo-based help across several subjects with a human backup. Other tools win on narrower jobs.

Solvely draws far less traffic: roughly 855,000 monthly visits against Gauth’s 14 million in an August 2026 snapshot (Toolmage). Photomath now belongs to Google, and its rules-based engine rarely invents steps. Google’s old Socratic app no longer exists; its homework features moved into Lens in 2025

Most students end up mixing tools anyway. Smart AI tools for students each handle one job: a planner for deadlines, a note app for lectures, a solver for the stuck moments.

The TRACE Method for Studying With Gauth

TRACE is a five-part routine that turns a quick answer into a skill you keep: Try, Reveal, Ask, Check, Echo. The idea mirrors a wider rule about AI that boosts thinking: you do the hard part first, and the tool critiques.

1. Try the problem on paper for five minutes. A wrong start still pinpoints the gap.
2. Reveal only the opening line of the solution, then close the app.
3. Ask why that line works before you read any further.
4. Check each line of working against your notes or Photomath, not just the final number.
5. Echo it by solving a similar problem cold, or save the mistake as a flashcard.

Two small habits help too. Crop photos tight in good light, and leave personal details out of the chat.

TRACE on a real worksheet question

Take this ninth-grade prompt: “the product of a number and 4, decreased by 7, equals 25.” The app spits out 4x − 7 = 25. Copying it earns one point.

A student using TRACE stalls on “decreased by,” peeks at line one, asks why it means subtraction, then solves x = 8 alone. Three practice translations later, the quiz question feels easy.

Final Thoughts on the Gauth AI Study Companion

The Gauth AI study companion earns a place on most students’ phones for fast, photo-first help. Stay on the free tier until you keep hitting the cap. If you upgrade, take the yearly plan and end it through Apple or Google, never the in-app menu.

The accuracy dip on harder material and the data collection both deserve an adult’s attention. The bigger question, though, sits with the student. Run this week’s three toughest problems through TRACE and notice whether the app teaches you something or just hands over answers.
