Learn it by doing.
Modelplay is a hands-on playground where you write real machine-learning code, run it instantly, and see the model train in front of you. No setup. No servers. Walk away with a portfolio that proves you can build.

YOU’LL TRAIN WITH
The loop
Four steps. One that you actually feel: the moment it learns.
- 01
Write
Fill the blanks in real scikit-learn code. No blank page, no setup paralysis — just the line that matters.
- 02
Run
Hit run. Python executes in your browser through WebAssembly. No installs, no servers, nothing to break.
- 03
See
Watch the model train and the plot render in front of you. Instant, visual proof that it worked.
- 04
Prove
Every pass becomes a portfolio artifact — code, result, and metric — you can send straight to an employer.
