The STEM Suite
ZeroAI Studio
Six apps in one place — circuits, block coding, Arduino, Python, 3D design and machine learning, for Grades 1–12. One sign-in, one dashboard. Open it in any browser, or install the desktop app and run the whole suite with no internet at all.
ZeroSpark
Circuits you can see
Children snap together batteries, lights, motors and sensors and watch the circuit come alive. Cause and effect, before any typing.
- Snap-together circuit canvas
- A real physics solver underneath, not an animation
- Progressive challenges and a combo map
- Teacher live-view of every canvas in the class
- Built for touch — tablets and small screens first
ZaiBlock
Block coding
Games, animations and stories built from visual blocks. Students program sprites with events, motion and logic, with no syntax standing in the way.
- Motion, looks, sensing and logic blocks
- Multi-sprite stage with live animation
- Speech and listening blocks for talking projects
- Models trained in ZaiMind drop straight in
- Teacher casting to every student screen
ZaiSim
Arduino and ESP32, simulated
A circuit simulator with real datasheet behaviour and a real C++ toolchain. Students write Arduino code, watch it run, then flash it to a board over USB.
- Pin-level circuit solver with real component models
- Real Arduino C++ compiled, not interpreted
- LEDs, servos, DHT22, HC-SR04, ESP32 and more
- Upload to a physical board — offline too
- Teacher broadcast, exams and progress tracking
ZaiPy
Real Python, real output
CPython in the browser through Pyodide — the same Python a university uses, with NumPy, pandas, Matplotlib and scikit-learn.
- A real editor with real syntax highlighting
- NumPy, pandas, Matplotlib, scikit-learn, OpenCV
- Turtle graphics and plotted charts
- Structured lessons and an exam mode
- Works with no internet — the runtime ships with it
ZaiCAD
2D drafting and 3D modelling
Sketch precisely in 2D, pull it into 3D, and export something a printer or a laser cutter can actually make.
- Precise 2D sketching with real dimensions
- Extrude and revolve a sketch into a solid
- Boolean combine and cut — real CAD thinking
- Export DXF for cutting, GLB and STL for printing
- Runs on lab hardware, no workstation needed
ZaiMind
Train your own AI
Students teach a model to recognise images, sounds or poses using their own camera and microphone, then test it live and see where it gets things wrong.
- Train on images, sound or body pose
- Every model trains on the device — nothing is uploaded
- Watch confidence change as you add examples
- Send a trained model into ZaiBlock or ZaiSim
- The honest lesson: models are only as good as their data
Built for real classrooms
Six apps behind one sign-in, and infrastructure designed for the schools other EdTech skips — low-power, low-connectivity, low-budget.
Runs on anything
Every app runs in the browser — no drivers, no install. Works on Raspberry Pi Zero, Chromebooks and shared lab machines with as little as 2 GB of RAM.
Works fully offline
The offline edition installs from a USB stick and never needs a connection again — Python and its libraries, the AI tutor, and Arduino compile-and-upload to a real board, all on the machine.
One place, one sign-in
The apps are not six separate products with six logins. One dashboard holds your classes, projects and competitions, and every app opens inside it.
A learning ladder
ZeroSpark → ZaiBlock → ZaiSim / ZaiPy → ZaiCAD → ZaiMind. Students climb from snapping circuits together to real Python, Arduino, CAD and machine learning.
Prefer to install it?
Get ZeroAI Studio as a native desktop app — all six apps in one window, fully offline, with local Arduino compile-and-upload built in. macOS, Windows and Linux.
