You paste in a raw transcript, the kind every speech-to-text tool produces: lowercase, unpunctuated, full of ums and self-corrections. The model rewrites it as text you would actually send. "so um i need to send the the report by uh friday no wait make that thursday" comes back as "I need to send the report by Thursday." It keeps the value you landed on when you correct yourself, renders spoken numbers, dates, prices, and email addresses in written form, and applies punctuation and capitalization.
A short control line at the top of the input steers the result: four registers from casual to formal, a list mode that turns real enumerations into bullets, and an email mode that lays out a greeting, body, and sign-off. It does exactly one job; it is not a chat model and will not follow general instructions.
The whole thing is 0.6 billion parameters, small enough that the compressed build is a 462 MB file running comfortably on a laptop CPU. This first release covers English only.
