Quick verdict
Bottom line up front: Gauth — originally Gauthmath — lets a student photograph a homework problem and get a step-by-step worked solution, starting with math and now covering subjects like science, history, and social studies. The free tier is limited enough that regular users hit its ceiling quickly, and Gauth Plus at $11.99/month removes the limits and the ads. The honest question is not whether it works, but how your student uses it: worked explanations can teach, copied answers cannot.
What does Gauth actually do?
Snap a photo of a problem — typed or handwritten — and Gauth’s recognition reads it and returns a solution broken into steps, not just a final answer. Animated and visual walkthroughs show how an equation or diagram changes as the solution proceeds, which suits visual learners better than a wall of text. Follow-up questions go to an AI tutor chat, a built-in calculator handles graphing and statistics work inside the same app, and PDF uploads cover textbook problems. Paid listings also advertise access to human expert help around the clock for questions the AI cannot settle, plus large libraries of tutorial videos and practice questions.
The app began in 2021 as a math-only helper during remote schooling and has since broadened into a general study companion, with reminders and focus features around the solving core.

Watch the trial mechanics: listings describe short free trials that convert to a paid subscription unless cancelled, and some user reviews complain about confusing billing and cancellation. Set a calendar reminder the day you start any trial.
What are Gauth’s strengths?
- Photo-first workflow: photographing a problem — including handwriting — beats typing equations into a chatbot.
- Steps, not just answers: worked, visual explanations give a student something to actually learn from.
- Subject breadth: no longer math-only; science and humanities questions are covered too.
- Cheaper than tutoring: even monthly Plus costs a fraction of one hour with a private tutor.
What are Gauth’s weaknesses?
- Tight free tier: the daily limit is fine for a check, not for a full problem set.
- Accuracy is not absolute: AI solutions can be wrong, and explanations sometimes show steps without teaching the underlying idea.
- Academic-integrity risk: schools may treat answer-copying as cheating regardless of the app’s learning framing.
- Billing complaints: trial conversion and cancellation friction appear repeatedly in user reviews.
- Internet required: no meaningful offline mode.
Pros and cons
Pros: fast photo solving with step-by-step explanations; visual walkthroughs; multiple subjects; human-expert escalation advertised on paid tiers; far cheaper than a tutor.
Cons: limited free use; occasional wrong answers; trial/billing complaints; does nothing for learning if used as an answer copier.
Who is Gauth for?
Middle-school, high-school, and early-college students working through daily problem sets — and parents who no longer remember the algebra well enough to help. It fits self-studiers who will re-work a problem after seeing the steps. It does not fit a student whose plan is to submit the app’s output as their own work.
Frequently asked questions
Is Gauth free?
There is a free, ad-supported tier with a limited number of questions per day. Gauth Plus — $11.99/month, or $99.99/year in US listings — makes solving effectively unlimited and removes ads.
What subjects does Gauth cover?
It started with math and now covers additional school subjects including science, history, and social studies, alongside writing and PDF helpers on paid tiers.
Does Gauth show its work?
Yes. Solutions come as step-by-step explanations, with visual and animated walkthroughs for many problem types.
Is using Gauth cheating?
That depends on your school’s rules and how it is used. Studying from worked steps is tutoring; submitting copied answers as your own work is not. Check your school’s policy first.
Verdict
Gauth is a capable, fairly priced homework companion whose value depends entirely on the habit it builds. Buy the annual Plus only after the free tier proves the explanations click for the student — and cancel any trial on time. This review is research-based; we did not hands-on test the product.
