typurr-sketch-0.8b — the Sketcher

The model that cleans your speech while you're still talking.

Typurr feeds it clauses from a streaming recognizer as you speak; it strips fillers, resolves self-corrections, punctuates, capitalizes, and formats spoken numbers — so the finished text exists before you release the key.

in (spoken) out
"um so basically can you send me the uh the report" "Can you send me the report"
"it costs ten dollars, uh, per seat and dana no wait marcus should get the invoice" "It costs $10 per seat and Marcus should get the invoice."

Numbers

~150 ms per clause on a laptop GPU (q8_0, llama.cpp). Trained on 58.8k synthetic (mangled-speech → clean-text) pairs from Typurr's data engine.

Coupling note: tuned to Typurr's exact system prompt (prompts.rs::SKETCH_RULES); with other prompts it still works, worse. Inside Typurr it runs behind a fidelity audit — outputs that invent names or numbers are caught and redone by a larger model.


Typurr — speak, it types. Nothing leaves your machine.

Typurr demo

A Windows dictation app and voice assistant that runs entirely on your own hardware: hold a hotkey, talk, release — finished text lands at your cursor in any app. No account, no telemetry, no audio in anyone's cloud.

  • Instant finish — its models clean your speech while you talk; the text is ready the moment you release the key
  • Speaks & listens — neural voice read-backs, review-before-send by voice, "typurr do…" compound commands, wake word
  • Learns you — your vocabulary, your corrections, your style; all in plain files on your disk
  • Gives AI agents a voice — local MCP server: your agents can speak, ask you questions aloud, and type at your cursor
