Step 1

Pick a Lesson and Start Typing

Select from preloaded Rust, HTML, CSS or JavaScript lessons, or import your own text files. The on-screen keyboard lights up with real-time heatmaps as you type.

Step 2

Get Contextual AI Explanations

As you type, a local LLM provides real-time explanations of the code or text you're practicing. The Context Insights panel shows what each line means, why it matters, and how to improve — all without leaving the typing flow.

Privacy

LLM Typing Trainer collects only what it needs — and everything stays on your device.

No user accounts, no email, no name.
All sessions, key statistics, lessons and schedules are stored in IndexedBD on your machine.
User preferences (theme, keyboard layout, cursor style) live in chrome.storage.local.
The optional LLM API key is stored locally; only configured users send data to a local server.
No data is sold or shared with third parties.
No remote scripts — the extension loads only its own bundled files.
