How it works

Make it, share it, learn from it

The same three steps work for a Grade 3 spelling quiz and a Grade 12 exam review.

  1. Step 1

    Make or find a test

    Build one in minutes with multiple choice, true/false, short answers and science symbols — or copy any test in the bank and make it yours.

  2. Step 2

    Share it with anyone

    Send a link that opens on any device, or assign it to a class with a due date. Students choose test mode or practice mode.

  3. Step 3

    Learn from every mistake

    Results show exactly what went wrong. Each wrong answer can become a flashcard that keeps coming back until it sticks.

Everything in one place

The bank, the flashcards and the classroom

Four tools that share the same tests, so nothing has to be made twice.

A test bank that keeps growing

Search tests and flashcard decks by subject and grade. Every public test a teacher or student shares becomes practice for everyone else.

Flashcards that remember for you

Flip, rate, repeat. Cards you’re unsure of come back sooner; cards you know wait until just before you’d forget them.

A builder that speaks science

Write x², x₂, Σ, √ and π, pick from four question types, and set a topic for every question. Already have tests? Bring them in from a Word or CSV file.

Classes without the paperwork

Share a class code, assign tests with due dates and see every score in one gradebook — plus the questions your class found hardest.

Who it’s for

Built for both sides of the desk

Whether you’re teaching thirty students or studying for one big exam.

Teachers

Less copying, more teaching

  • Copy a test from the bank and edit it instead of starting from zero.
  • Assign it with a due date and see who hasn’t started.
  • Find the question that tripped up the class, and re-teach it.
  • Keep each test public, class-only or private.

Students

Practice that actually sticks

  • Practice any subject or grade, even without an account.
  • Get your mistakes back as flashcards, so they don’t happen twice.
  • Keep a streak going with a small daily goal.
  • Make your own tests and share them with friends.

Schools & parents

Safe, simple and in your control

  • Students join a class only with a code from their teacher.
  • Teachers decide who can see every test they make.
  • Progress for the whole class, visible at a glance.
  • Accounts for users under 16 need a parent or guardian’s consent.

Roadmap

Where Dymini is going

Dymini is an early-stage project started in 2026. Here is what it does today and what we are building next.

  1. Available

    Tests, flashcards and classes

    Make and share tests, practice with flashcards, and follow your scores, topics and streaks.

  2. In progress

    A personal tutor for science

    Practice for natural-science subjects that adapts to each student, like having a tutor who knows where you struggle.

  3. Planned

    Connect your AI assistant

    Link tools like ChatGPT, Gemini and Claude so an AI can summarize a lesson, then create a test or practice set on Dymini for you to take and track.
