Terms of Use

You're welcome to read, use, and train models in every playground on this site for any purpose - personal learning, teaching a class, or just curiosity. No account or payment is required for any of it.

The source code for this site is source-available under a dual license (see the LICENSE file in the project repository): free to read, fork, and reuse for noncommercial use under the PolyForm Noncommercial License 1.0.0; any commercial use requires a separate paid commercial license (see COMMERCIAL-LICENSE.md). The written explanations and diagrams follow the same terms, free for noncommercial learning and teaching, with a link back appreciated but not legally required.

This site is provided "as is," without warranty of any kind. It's maintained on a best-effort, volunteer basis. While we try hard to keep every explanation accurate, this is educational material, not professional or academic advice - always cross-check anything load-bearing (a homework answer, a production ML decision) against a primary source.

Please don't attempt to disrupt the site (excessive automated scraping, denial-of- service attempts, or similar) or use it to distribute malware or unlawful content. Aside from that, there's very little we ask of you here.

A few pages link to outside resources credited as prior art (for example, TensorFlow Playground and CNN Explainer). We don't control those sites and aren't responsible for their content or availability.

To the fullest extent permitted by law, the maintainers of this site aren't liable for any damages arising from your use of it. It's a free educational tool, not a service with guarantees.

These terms may be updated occasionally; the "Last updated" date above will reflect the most recent change, visible in full in the project's public commit history.

See the Privacy Policy for how data is (and mostly isn't) handled.
