The math solver built for the classroom.

Zeretis is a classroom tool that makes mathematical thinking visible. Project solutions live, verify student working instantly, and generate unlimited worked examples — all from a single browser tab.

🏫 Safe for classroom use. Students can use Zeretis independently without risk of off-topic content. The solver only responds to math — by design, nothing else is possible.
Live classroom demo
Teacher enters (projected on whiteboard) integrate x^2 * e^x dx → x²eˣ − 2xeˣ + 2eˣ + C
Step 1 — integration by parts: u = x², dv = eˣdx = x²eˣ − ∫2x·eˣ dx
Step 2 — apply by parts again = x²eˣ − (2xeˣ − ∫2eˣ dx)
Step 3 — simplify = x²eˣ − 2xeˣ + 2eˣ + C ✓

Type it however is fastest for you.

In the middle of a lesson you don't want to faff with notation. Zeretis accepts plain English, standard math notation, and LaTeX — use whichever is quickest in the moment. Your students can use whichever they're most comfortable with too.

Three ways teachers use Zeretis every day.

1

Project solutions live

Open Zeretis on your classroom display and enter problems together as a class. Every student sees every transformation in real time — not just the finished answer written on a board, but the reasoning behind each step. You can pause, ask students to predict the next step, and discuss why each rule applies. It turns a static worked example into an interactive session.

2

Verify student working instantly

When a student brings you their working, enter the same problem and compare their steps to the solver's output. You can immediately see whether their method was correct (even if they made an arithmetic slip) or whether the approach itself was wrong. This gives you much faster, more precise feedback than checking manually — and students can do the same comparison themselves.

3

Generate worked examples on demand

Need five variations of the same problem type for practice? Enter each one and get a fully worked solution in seconds. Use the output as ready-made examples for worksheets, revision guides, or live demonstrations. You can generate more variety in ten minutes than you could write by hand in an hour.

Built around how teachers actually work.

Every feature is designed to fit into a classroom context — fast to access, easy to project, and safe to put in front of students of any age.

📺

Projection-ready layout

Clean, high-contrast output that reads clearly on a projector or interactive whiteboard. Step-by-step structure is designed to be followed together as a class.

Instant — no loading waits

Symbolic computation is fast. Results appear immediately — no waiting during a live lesson while a model loads or an API times out. Every second counts in a 50-minute class.

🔒

Safe for independent student use

Assign Zeretis for homework or self-study without worry. The solver only responds to math — students can't use it to generate essays, access social features, or go off-topic.

📚

Full curriculum coverage

Algebra through differential equations — the solver handles the full secondary and undergraduate curriculum. One tool for every year group you teach.

✏️

Natural language input

Type problems the way you'd say them in class. No need to switch mental modes into LaTeX syntax when you're mid-explanation. Students can do the same.

💳

Affordable for classrooms

Personal subscriptions start at under $4/month. Classroom and school pricing available — contact us to discuss group rates for your department or institution.

Why you can assign it without worry.

Zeretis is not a general-purpose AI assistant. It's a symbolic math engine with a strictly limited scope — which is exactly what makes it appropriate for independent student use.

🚫

Can't go off-topic

There is no language model component to manipulate. The solver only processes mathematical input and returns symbolic output. Attempts to use it for anything else simply don't work — not because of a content filter, but because of how the system is built.

🛡️

No data collected on students

Student queries are processed and discarded — nothing is stored, logged, or associated with a student's identity. No account is required for the free tier, which means you can point students at Zeretis without any data collection concerns.

📵

No social features or distractions

Zeretis is a focused tool — there is no feed, no comments, no notifications, no recommendations. Students open it, solve a problem, and close it. No rabbit holes.

Consistent, auditable results

Because results are deterministic, you can run the same problem yourself and verify exactly what a student would have seen. There are no random or variable outputs to worry about.
