# What the Coach can do (/docs/using/coach/what-it-does)

The Coach is a chat in WriteStack, with an owl called Quill. It reads your notes, posts and stats, drafts notes and posts in your voice, and saves or schedules notes when you ask. It's included on every paid plan. How much you can use it depends on the plan: see [Coach limits](/docs/using/coach/limits).

## Open it [#open-it]

Click **Coach** in the sidebar. A new chat opens with "How can I help you grow?" and four starters:

| Starter | What it asks |
| --- | --- |
| **Paid growth** | What to focus on to grow paid subscribers |
| **Note impressions** | When your notes get the most impressions |
| **Schedule a job** | Set up a [routine](#routines) that drafts notes every weekday morning |
| **Write notes** | Five notes in your voice, on a topic you finish typing |

You can also type any question. A message can be up to 40,000 characters and carry up to 4 images.

## What it knows [#what-it-knows]

| Source | What the Coach reads |
| --- | --- |
| Your notes | Drafts, ready, scheduled and published notes. It learns your voice from published ones. |
| Your posts | The posts on your newsletters, so it can find one by title and write from it. |
| Notes statistics | Impressions, reactions, restacks and more. Needs Standard or Enterprise and the [extension](/docs/using/setup/browser-extension). |
| Posts Statistics | Views, opens, open rate, signups and more per post. Needs Standard or Enterprise and the extension. |
| Comments and mentions | The same feed as the Activity Center. |
| Your queue and schedule | Your slots and what is scheduled. |
| Your [writing style](/docs/using/concepts/writing-style) | The voice it writes in. |
| The Writing Edge | WriteStack's research on what works on Substack, plus playbooks for notes, posts, titles, SEO, growth and paid subscribers. It links the source it used. |
| Inspiration | Top notes by other writers, the same search as the Inspiration page. |
| The public web | Current public pages, when the answer depends on one. |
| [Memory](#memory) and [Library](#library) | Facts and files you gave it. |

## What it can do [#what-it-can-do]

| Ask for | What happens |
| --- | --- |
| Notes | It writes each note as a **Note** card. Click a card to open it in the note editor. |
| Save notes | Saves notes as draft or ready. |
| Schedule notes | Saves notes and puts them on your queue, in the next open slots unless you name a time. Needs the browser extension, from a computer. See [Sync](/docs/using/concepts/sync). |
| Evergreen notes | Turns a note into an evergreen note that repeats. Needs the extension. |
| Tags | Adds or removes tags on your notes. |
| Cross-posting | Adds [cross-post channels](/docs/using/cross-posting) to a note, or writes a version for one platform, when you ask. |
| Posts | Writes a post and saves it as an article. See [How the Coach writes articles](/docs/using/articles/coach-articles). |
| Push a post to Substack | Sends the article to Substack as a draft. |
| Images | Makes or edits one image per message, for example for a note. |
| Charts | Draws a chart from your numbers. |
| Answers | Explains your stats, what works on Substack, or how to use WriteStack. |

The Coach can't publish anything, and it doesn't act on your notes or articles unless you ask. See [What needs your approval](/docs/using/coach/approvals) and [what the Coach can't do](/docs/using/coach/limits#what-the-coach-cant-do).

When two options are close, the Coach asks you with a question card instead of guessing. Pick an option, or type your own under **Something else**.

## Chats [#chats]

Each conversation is a chat. Your chats are listed by date, next to **Memory**, **Library** and **Routines**.

- **New chat** starts a fresh conversation.
- A chat made by a routine is labeled **Routine**.
- To delete a chat, click its delete button, then **Delete chat**. Its messages are deleted. Memory facts saved from it stay.
- The Coach can find an earlier chat when you refer to it, for example "like we discussed last week".

Questions sent through [`ask_coach`](/docs/build/mcp-reference/ask_coach) from an AI agent are saved as Coach chats too.

## Memory [#memory]

**Memory** holds facts about you and your publication: audience, goals, offers, voice, preferences. The Coach saves useful facts from chats and uses them next time.

- Ask "Remember that I publish on Tuesdays", or type it under **Add a fact**.
- Edit or delete any fact. **Delete all** clears them.
- Turn **Use memory** off and the Coach won't save new facts or use the saved ones.

The Coach doesn't save facts about other people, health, politics, religion, credentials or personal finances.

## Library [#library]

**Library** holds material you want the Coach to search: a public link, pasted text, or a file (.txt, .md or PDF). Give each item a title. Only you can search your Library. The Coach searches it when you ask.

## Routines [#routines]

A routine is a Coach job that runs on a schedule, every day or every week. Examples: morning note drafts, a weekly review of your note stats, a queue health check, or an accountability check-in against a goal.

1. Ask for it in a chat. The Coach shows a card with the name, **When**, **Timezone**, **Does** (**Saves drafts** or **Writes a report**) and **Delivery**.
2. Click **Confirm** to save it. Nothing is saved until you do.
3. Manage it under **Routines**: **Run now**, **Pause** or **Resume**, or delete it.

Each run posts its result in its own chat and by email. A routine can save drafts or write reports. It can't schedule or publish. Routines are on Standard and Enterprise. Limits are on [Coach limits](/docs/using/coach/limits#routines).
