Semantic Command Palette
EmbeddingsA ⌘K palette that understands intent: describe what you want in your own words and the right action lights up.
Why On-Device?
Intent matching on every keystroke is only viable when embedding is free, instant, and private — exactly what an on-device embedder provides.
Interactive Demo
Semantic Embedder: Loading...
The palette embeds its 14 actions once, then ranks them on every keystroke.
Try an intent:
Executed
Press Enter or click an action to run it.

Semantic vs. Keyword Search
Search a help center by meaning, side by side with keyword search — and watch keywords miss what embeddings find.
