NanoChat

NanoChat is a minimalist AI web chat by Andrej Karpathy built for quick, text-first conversations. The interface is intentionally reduced to a single chat window, with no extra settings or distracting UI elements.

Built for small-model experiments

NanoChat is designed as a simple way to see how compact language models behave in real dialogue. You can type a prompt in plain text and immediately review the model’s response, which works well for quick checks and lightweight tasks.

• Rapid prompt trials and iterations
• Short explanations and Q&A
• Quick code-related questions and sanity checks

Useful for testing and learning

The stripped-down format makes NanoChat a practical tool for prompt debugging and learning the basics of working with modern language models. It can also serve as a helper while reading articles, studying documentation, or handling small tasks where you want fast, focused answers.

Focus on simplicity and speed

With no complex menus, you can open the page and start chatting right away. NanoChat fits users who want an easy entry point to AI chat without a feature-heavy interface.
