Zeretis is focused, private, and safe. It only does math — it can't go off-topic, won't engage in open chat, and collects no personal data about your child. Ever.
Children don't need to know special math notation or LaTeX to use Zeretis. They can type their problem the way they'd ask a teacher — in plain English. The solver understands and gives them a full step-by-step solution.
Unlike general AI assistants, Zeretis has a strictly limited scope. It solves math problems and shows the working. That's all it does — which is exactly why it's safe for unsupervised use.
We don't collect, store, or sell your child's queries. Nothing is logged or associated with their identity. A free account is required to track usage — no query data is stored — only anonymous usage counts are stored — never query content or personal data beyond your email.
The solver only accepts mathematical input. Attempts to use it for anything else — asking for stories, advice, or general chat — are rejected with a message pointing back to math. This is a technical constraint, not a filter.
Zeretis uses symbolic computation, not a language model. There is nothing to hallucinate, no "personality" to manipulate, and no way to prompt it into unexpected behaviour. It either solves the math or says it can't.
Every solution shows every step. If your child tells you "the solver showed me how to do it", you can run the same problem yourself and verify exactly what they saw. Completely transparent.
No advertising, no tracking pixels, no data brokers. Your child's attention and data are not being monetised. Zeretis is funded by subscriptions, not by advertising.
Browser-based with no installation required. Works on school-managed Chromebooks, iPads, and any other device your child uses for homework.
The most common concern parents have is that their child will use a solver to copy answers without learning. Zeretis is designed with this in mind — the steps are the point, not just the answer.
"Showing the answer without showing the working would be actively unhelpful — you'd pass tonight's homework and fail Friday's test. Zeretis shows the method so students can replicate it themselves."
When your child uses Zeretis, they don't just get an answer — they get a full breakdown of every mathematical step taken to reach it, with each rule or property labelled. The output looks exactly like a textbook worked example.
Encourage your child to read each step carefully before moving on, then try a similar problem themselves without looking. That process of "understand, then attempt independently" is where actual learning happens — and Zeretis is designed to support it.
Zeretis also gives you a way to check your child's understanding. Ask them to explain one of the steps back to you. If they can, they learned something. If they can't, that's a conversation worth having — and the step-by-step breakdown gives you a shared reference point for the discussion.
The free tier of 10 problems per month is also a natural constraint that discourages mindless copying — it encourages children to use Zeretis thoughtfully, for problems they're actually stuck on.
No special syntax needed. Your child types the math problem the way they'd say it out loud — "how do I solve 3x plus 7 equals 22" — and the solver understands. Older students can also use standard notation or LaTeX if they prefer.
The solver shows every transformation applied — not just the final answer. Each step is labelled with the rule used (balancing, factoring, substitution, etc.) so your child can follow the reasoning and understand what happened at each stage.
The goal is for them to understand the method well enough to tackle a similar problem without looking. Using Zeretis to understand how something works — then closing it and trying independently — is the intended pattern. That's what actually prepares them for assessments.
The solver handles math from primary level (basic arithmetic, fractions) through to university undergraduate level (calculus, differential equations, linear algebra). The natural language input makes it accessible from a young age — children don't need to know notation to use it. There is no minimum age requirement, and the content is entirely math-focused so there is nothing age-inappropriate to encounter.
Yes — the free tier (10 problems per month) requires a Google account sign-in so we can track your child's usage limit. Only an anonymous usage count is stored — no query content, no browsing behaviour, nothing else. Your child can use Zeretis without you needing to provide any data at all. An account is only required for paid subscriptions, and we ask for an email address only for billing purposes via our payment processor Paddle.
Yes. Zeretis is a browser-based tool with no download required. It doesn't request any device permissions, doesn't use cookies for tracking, and doesn't have social features. There's nothing a school IT policy would object to, and it can be accessed from any device with a browser.
It will solve math problems — that's the point. Whether that helps or hurts depends on how your child uses it. A child who reads the steps and tries to understand the method is learning. A child who copies answers without engaging will still struggle in tests. The step-by-step output is designed to encourage the former — it's much more useful as a learning reference than as an answer machine.
The solver will not respond. It only processes mathematical expressions and returns symbolic results. Anything that isn't a math problem — whether that's inappropriate content, a request for general chat, or a question about something else entirely — gets a response explaining that Zeretis only handles math. This is a fundamental constraint of the system, not a filter that can be worked around.
Free to start, a free account is required to track usage, safe for all ages. See why parents trust Zeretis for independent homework help.
