## Set One Up

Four steps in Terminal and ZenVoice. Swap in kanso-koi-1.0 or kanso-koi-0.9 for Koi.

1.  1
    
    Install the command
    
    In ZenVoice, open Settings → Transcribe and install the command-line tool.
    
2.  2
    
    Download the model
    
    From its pinned source; every file's size and SHA-256 is checked.
    
    `$ zenvoice formatting install kanso-satori-1.0`
    
3.  3
    
    Choose it
    
    Dictation and recordings use it from the next dictation.
    
    `$ zenvoice formatting use kanso-satori-1.0`
    
4.  4
    
    Turn on Polished
    
    In ZenVoice → Formatting. Clean and Verbatim don't use a formatting model.
    

## Commands

One command manages every formatting model, current and legacy. Add --json to any of them for scripts.

CommandWhat it does

-   `zenvoice formatting`
    
    Lists every formatting model, marks the one in use with \*, and labels the legacy ones.
    
-   `zenvoice formatting install <id>`
    
    Downloads a model and checks it. Run it again to resume an interrupted download.
    
-   `zenvoice formatting use <id>`
    
    Makes it the model Polished formatting uses.
    
-   `zenvoice formatting use kanso-sumi-1.0`
    
    Goes back to a current model. Choosing any model in the app does the same.
    
-   `zenvoice formatting remove <id>`
    
    Deletes a model that isn't in use, to free the disk space.
    
-   `zenvoice doctor`
    
    Shows which formatting model is in use and whether it's installed.
    

Installing and choosing a model need your ZenVoice licence, as transcribing from Terminal does. A model in use can’t be removed; choose another first.

## In the App

ZenVoice shows a legacy model only while it is the one you use.

### Shown while chosen

While a legacy model is your choice, the Models page shows it, marked Legacy, and the Formatting page names it.

### Gone when you switch

Choose any other formatting model in ZenVoice and the legacy one leaves the app. Only zenvoice formatting use brings it back.

### Never a download

The app never offers a legacy model. If its files are missing, dictation uses Apple Intelligence, or the rules, until you install it again.
