Prior AI already knows your tasks, projects and notes. The page you have open adds one more thing: it lets you say "this note" or "here" and be understood. A small chip directly above the composer shows what it will read.

## What the chip shows

- **On a note,** the note's title. Prior AI reads the note's text, up to 12,000 characters.
- **On a project,** the project's name and the tab you are on, such as Board or Budget. Nothing else is added: the project's tasks come from the usual workspace data.
- **On any other page,** the name of the page, such as Today or Calendar.
- **With a passage selected,** the start of that passage, in quotes. Up to 4,000 characters of it go with the next message only.

## Leave it out

Click the **×** on the chip (**Leave … out**) and the page is not read for your next messages. The chip turns into a **+** (**Use … as context**): click it to put the page back.

The chip comes back on by itself when you open another page, and in a new conversation.

## Ask about a note or a passage

- In a note's toolbar, click **Ask Prior AI**. The assistant opens on that note. If you had selected text in the note, it goes along.
- Select text in the note editor and click **Ask AI** in the formatting bar.
- Open a block's menu (the handle on its left) and choose **Ask Prior AI about this**.

Then ask for what you want: "Make this a table", "Fix the spelling", "Add a summary at the top", "What is missing from this plan?".

## How it edits a note

A change to a note comes back as a card showing the note as it will read. It can do three things:

- replace the whole text, to restyle or reorganize,
- add text at the end,
- add text under a heading you name.

Applying it first saves what you typed. Tables, charts, callouts and toggles are all plain text in a note, so the assistant can write them.

## Good to know

- **A long note is cut.** Past 12,000 characters Prior AI sees only the start, so it adds to the end or under a heading and does not rewrite the whole note.
- **A shared note** can be changed from the assistant only while that note is open on your screen. The edit is small and reaches people reading it live, without moving their cursors. A viewer of the project gets no proposal for it. See [Shared notes](https://priortasks.com/docs/notes/shared-notes/).
- **Pages that are not notes** give the assistant a name, not content. To work on a long text, put it in a note and open the note.
- **Projects.** A task it proposes goes into a project only if you named that project, or if you have it open with the chip on.
