What Is Gauth AI Study Companion? How to Use It
Gauth (formerly Gauthmath) is a homework help app where you photograph a problem and get back a worked, step-by-step solution, plus a chat window for follow-up questions. It leads with math and covers other subjects behind that, runs on iOS, Android and in a browser, and meters free use before asking you to subscribe. It is a solver first and a study companion second, and that distinction changes how you should use it.
What Gauth actually does
Feature names and free limits shift between app versions and regions, so read the table below as the shape of the product rather than a spec sheet. Check the current version before you pay for anything.
| What you give it | What comes back |
|---|---|
| A photo of one problem | A step-by-step solution with the final answer |
| A typed or pasted question | The same, usually cleaner because there is no OCR step |
| A follow-up message in chat | An explanation of a single step, a rephrasing, or a similar problem |
| A document or a set of pages | A summary or answers pulled out of that text |
Earlier versions of the app also routed some questions to human tutors, which is worth knowing because that is a different product from an AI solver: slower, and answering a question a model got stuck on. Free access has generally been credit based, with a paid tier for unlimited questions.
The important part is what the product is optimized for. Gauth is built to close a specific loop: you are stuck on question 14, and you need question 14 finished. Everything about the interface, from the camera opening on launch to the answer appearing above the explanation, serves that loop. It does it well. It just is not the same loop as preparing for an exam, which is why choosing the right tool depends on what your material actually looks like.
How to use it without skipping the learning
Step 1: attempt the problem cold for five minutes
Set a timer and write something, even a wrong first line. The value of the solution depends almost entirely on whether you have a wrong attempt to compare it against. Reading a correct solution with nothing of your own on the page produces recognition, not understanding, and recognition disappears under exam conditions.
Step 2: send one problem at a time, cropped tight
Photograph a single question, not the whole page. Crop out the neighboring problems, the header, and your own handwriting in the margin. Multi-problem photos are the most common cause of an answer that solves the wrong thing, and stray handwriting confuses the text recognition. If your handwriting is involved at all, type the problem instead.
Step 3: read the solution once, then cover it
Read through to the end so you know where it is going. Then cover the screen and reproduce the solution on paper. The point where you stop is the actual gap. Everything before that point you already knew, and everything after it you have not learned yet, you have only watched.
Step 4: ask "why", not "what next"
The chat window is where the app becomes a tutor instead of an answer key. Useful prompts sound like: "Why is line 3 valid?", "What rule lets you factor that?", "Give me a similar problem with different numbers and do not solve it." Unhelpful prompts sound like: "Do the next one." The second kind gets you through the assignment and leaves nothing behind.
Step 5: redo the problem from a blank page the next day
Not the same evening. Open a blank page, write the problem from memory if you can, and solve it with the app closed. If you cannot, you found a real gap rather than a comfortable feeling of one. This single step is the difference between a homework tool and a study tool, and it costs about four minutes.
Where solvers get things wrong
Photo based solvers are strongest on cleanly typed, single answer problems: algebra, calculus mechanics, stoichiometry, unit conversion. They degrade in fairly predictable places. Diagrams and graphs where the information is in the picture rather than the text. Multi-part problems where part (b) depends on your answer to part (a). Proofs, where a confident and completely invalid chain of steps looks exactly like a valid one. Word problems with an unusual setup, where the model pattern matches to a similar-looking problem and solves that instead.
The practical defense is boring and effective: check the final answer against the back of the book or the answer key when one exists, and treat a solution you cannot follow as unverified. An explanation you cannot reproduce is not evidence that the answer is right.
What a solver cannot do for you
Here is the honest limit, and it is not about accuracy. Exams do not ask you to recognize a correct solution, they ask you to produce one from an empty page. Reading worked solutions, however good they are, is closer to rereading a chapter than to testing yourself.
The evidence on this is old and unusually clear. In Roediger and Karpicke's 2006 experiments, students who read a passage and then took recall tests remembered substantially more a week later than students who simply restudied the passage, even though the restudy group predicted they would do better. Dunlosky and colleagues' 2013 review of ten common study techniques reached a similar conclusion: practice testing and distributed practice earned high utility ratings, while rereading and highlighting, the two things most students actually do, earned low ones.
So a solver handles the part of the night where you are stuck, and something else has to handle the part where you find out what you would fail to reproduce tomorrow. That second part means generating questions from your own material and answering them from memory: turning a chapter into a study guide you can be quizzed on, or turning your notes into multiple choice questions that test the specific things your class covered. Qora does that half: you hand it a photo of your notes, a recording of the lecture, or text you typed, and it produces a short lesson and questions built from that material rather than from a general question bank.
Common questions
Is Gauth free?
There is a free tier, but it is metered. Free use has generally worked on a credit system where each solved question costs something, with a paid subscription for unlimited questions and faster or more detailed answers. Pricing and limits vary by region and change over time, so check the current numbers in the app rather than trusting any figure you read in an article.
Is Gauth accurate?
It is reliable on standard, cleanly presented problems and less reliable on diagrams, proofs, and multi-step word problems. The failure mode to watch for is not an obvious error but a confident, well-formatted solution that is wrong in one step. Verify the final answer independently when you can, especially on anything that will be graded.
Is using Gauth cheating?
That depends entirely on your course policy, and policies differ sharply. Checking your own completed work against a solver is usually acceptable. Submitting generated answers or generated writing as your own is prohibited almost everywhere and is increasingly detectable. Read the syllabus or the academic integrity policy before you decide, not after.
Does it work for subjects other than math?
Yes, with a quality gradient. Physics and chemistry problems that reduce to equations behave much like math. Biology, history and literature questions get answers, but they are more like general chatbot answers and less tied to what your specific course emphasized. For memorization-heavy subjects, a solver is the wrong shape of tool: you need repeated retrieval, not one good explanation.
Gauth answers the question in front of you, and that is a real problem worth solving at eleven at night. Use it that way deliberately: attempt first, one problem per photo, ask why instead of what, and redo the problem cold the next day. Then spend fifteen minutes turning the chapter into questions you have to answer from memory, because that is the format the exam will use.
