[ My playground ]

A place to build, try, explore, and keep learning.

This is my hands-on space for apps, websites, tools and experiments. Some are live, some are downloads, and others are research or work in progress. For my experience, resume and professional work, visit my professional portfolio.

Privacy where it matters

HAI Messenger encrypts message content end to end, and each app documents its own data and model boundaries on its information page.

Direct, useful access

No ads and no confusing detours. You learn about an application first, then launch it from a single, clearly labeled Try Now action.

Always experimenting

Live applications, prototypes and research sit side by side. Each project explains what you can try and where its limits are.

Field notes

Why does every app open an information page first?

So you can see the purpose, features, workflow, technology, data handling, limitations, and screenshots before entering the application. Use the playground directory for direct access, or read the project guide before trying an app.

Is HAI free?

There is no paid tier, subscription, or advertising layer. The applications are operated on HAI's own server infrastructure.

What does self-hosted mean here?

The applications run on infrastructure controlled by the project rather than being assembled entirely from third-party hosted frontends. Individual information pages explain where external services or models are currently used.

Where can I see every project?

Choose Playground in the navigation to explore every project. Open a live app or download when available, or choose Project guide for its details.
