Transcript cleanup

Polish

Clean a speech-to-text transcript in the tab: drop fillers, resolve self-corrections, write numbers and emails, and apply punctuation. Pair it with Scribe, or paste any rough transcript.

What it does

Turn raw dictation into written text.

  • S1-mini by Superwhisper (keep that exact name). Fine-tuned from Qwen3-0.6B to do one job: normalize English ASR output. It is not a chat model.
  • Pass styling (casual · semi-casual · semi-formal · formal), structure (prose · lists) and context (general · email). Defaults are semi-formal prose.
  • English only. Keep a single pass under ~1,000 tokens; chunk longer transcripts at sentence boundaries.
  • Filler-only input (um, uh) returns an empty string. That is a valid result, not a failure.
  • WebGPU prefers q4f16 (~339 MB) and falls back to q4 (~385 MB) if the session fails to start. WASM uses q4.

Questions about Polish

Does Polish run on device?

Yes. Weights download once and stay in the browser. Nothing is sent to a server.

What does Polish cost?

Nothing. runonweb is free and MIT-licensed, with no device limits, tokens or sign-in.

Which browsers support Polish?

Chromium browsers use WebGPU. Firefox and Safari fall back to WebAssembly automatically, slower but identical output.

Can I use a different model with runonweb/clean?

Yes. See each module’s docs for the options it accepts (model, size, language…). Check the license and test both backends before shipping.
