S1-mini by Superwhisper and Its Writing Style Settings

S1-mini is a small AI model, made by Superwhisper, that tidies up dictated text. It is the lightest of the two on-device AI Polish options, next to EG-1. It runs entirely on your Mac, it is free, and there is no API key to manage. To use it, open Settings > AI Polish and pick S1-mini.

Should I pick S1-mini or EG-1?

EG-1 stays the recommended choice. Pick S1-mini if you dictate in English and want the lightest on-device option, or if EG-1 is more than your Mac has room for.

• Small download. S1-mini is a 484 MB download, about a sixth the size of EG-1. It starts faster and uses far less memory. It needs around 1 GB of free disk space while it installs.
• English first. It cleans up other languages without translating them, but it may miss a mid-sentence correction you make in those languages.

Why was my long dictation not polished?

S1-mini works best on short and medium dictations. When a dictation is longer than S1-mini can polish, the app skips polish for that dictation and gives you the cleaned-up transcription instead. The S1-mini card under Settings > AI Polish shows how long a dictation it can polish. If you often dictate for longer, EG-1 handles longer dictations.

Make the text more casual or more formal

Set Tone on the Writing style card. To find the card, open Settings > AI Polish and pick S1-mini. A change applies to your next dictation.

• Casual and Semi-casual write the way you would text.
• Semi-formal keeps capitals and full stops. This is the default.
• Formal keeps capitals and full stops and is the most formal of the four.

Turn a spoken list into bullet points, or stop it

Set Structure on the Writing style card.

• Lists turns “apples, oranges, bananas” into bullet points when you speak a run of items. Ordinary sentences are left alone. This is the default.
• Prose keeps everything as sentences.

Get a greeting and sign-off laid out for an email

Set Context on the Writing style card.

• General is the default and changes nothing about layout.
• Email lays out a greeting line and a sign-off block when you dictate them. It does not invent a greeting or a signature that you did not say, so a plain sentence comes out the same under either setting.

Every writing style setting starts on its default. If you never open the card, S1-mini behaves the way it did before the card existed.

Use S1-mini through Ollama

If you pulled S1-mini into Ollama yourself and selected it there, EnviousWispr recognises it and sends it the same instructions it sends the built-in copy. The Writing style card appears on the Ollama page for that model too. For Ollama setup, see Using Ollama for Fully Offline AI Polish.

Where does the S1-mini name and licence appear?

Superwhisper’s licence asks that the model is identified as S1-mini wherever it appears, and EnviousWispr does that. The licence and notice files ship inside the app under Open Source Licenses.
