About

NumPy Lab is an AI-built single-page app in the education category (numpy exercises). It opens in your browser, so there is nothing to install. You provide python code and get executed results. Your input is processed on your device and not uploaded. It needs no account. It is a plain tool: no AI model is involved. The source code is public on GitHub (simonw/tools).
