# Coach a note

> Ask a model for a closer read of a draft, with a spending limit and a Stop button.

The coach reads the whole draft against your profile. It marks the places that need work, gives a short summary and a score out of 10, and hands its marks to the same card as the local checks. It runs only when you ask.

## Before you start

- Model Hub is installed and enabled, with a provider set up in it. Learning Editor needs Model Hub's API 0.10 or newer.
- A model is set for the coach. The coach's role in Model Hub is `learning-editor.coach`, on the **careful** tier unless you change it. To pick a model, open **Settings → Learning Editor** and select **Choose the coach’s model**.
- A profile helps but isn't required. Without one, the coach uses plain defaults.

## Steps

1. Open the note.
2. Run **Coach this note** from the command palette, or select **Coach** in [the panel](the-panel.md).
3. Watch the status bar. It follows the run: for example *Coach: step 2 of 8, counting habits, $0.01 of $1.00*.
4. When the run ends, a notice says how many places the coach marked and its score. The marks appear in the note.

To stop a run, click the status bar item or select **Stop coaching** in the panel, where **Coach** becomes **Stop coaching** while a run is going. A stopped run saves nothing.

## What you get

- The coach's marks, in the note, on the card. Apply and dismiss them as any other mark: see [Work with marks](work-with-marks.md).
- Its summary and score in the **Coach’s last read** section of [the panel](the-panel.md).

Every mark is checked against your note before it's saved. A mark whose words can't be found in the note is left out, and the notice says how many couldn't be placed. Where a coach mark overlaps a local one, the coach's mark is shown.

## What it costs

Each run is one model run through Model Hub, billed by your provider. It stops at **Spending limit per run** (US$1 unless you change it, in [Settings](settings.md)) and after 8 steps. Model Hub's own limits on the tier apply too. If the run reaches a limit after it handed in marks, those marks are kept; if not, nothing is saved.

## What is sent

The note's text and your profile, to Model Hub, which sends them to the provider you chose. Nothing else from your vault. See [Privacy and costs](privacy-and-costs.md).
