Writing with AI

The two places it appears

There is no separate AI mode to switch into. It shows up in two places, and which one you want depends on whether you have something selected.

• Select a passage and the format panel offers to rework those exact words.
• Select nothing and the panel on the right is a conversation about the whole document. Type / and choose Ask AI, or use the button at the foot of the page.

Changing a passage

1. Select the words you want changed.
2. In the panel that opens, choose one of four: Improve to make it clearer, Shorten to cut it down, Expand to add useful detail, or Fix grammar to correct mistakes and change nothing else.
3. The new version is written over the old one on the page, tinted so you can see exactly what changed.
4. Choose Accept to keep it or Reject to put back what was there.

Accepting or rejecting

Nothing the assistant writes lands in your document without you saying so. While it is working, the panel says Writing on the page and offers Stop. When it has finished, it asks Accept this writing? and waits.

Until you answer, the new text is marked as unsettled. Rejecting removes it and restores what was there before.

Asking about the document

The panel on the right is an ordinary conversation, except that it can already read the document you have open. Ask what it says, what is missing from it, or what a section is really arguing.

It also writes. Ask a question and the answer appears in the panel; ask it to write something and the answer goes on the page instead, at the point you were last typing. You do not choose between the two: it works out which you meant. Anything written on the page still has to be accepted.

Review and title

Two things it does read the whole document rather than answering a question, and both are offered in the panel before you have typed anything.

Review my writing reads the draft as an editor would, on behalf of whoever the document is written for. It looks for abbreviations used before they are explained, terms that reader would not know, missing background, and anything ambiguous, and quotes the passage in each case. If the document reads clearly it says so rather than inventing problems.

Suggest a title comes back with a title and a one line summary, both read off what you actually wrote. There is a button to apply the title to the document.

Explaining code

A code block has an explain action of its own. It describes what the code does in plain English, explaining each technical term the first time it comes up, and assumes nothing about whether you write code yourself. The explanation is written onto the page under the block.

What an action costs

One request is one action. Reworking a passage, asking a question, a review, a title, an explanation: each is one, whatever its length. The allowance resets every month.

• Free. 25 actions a month, all answered by the quick model.
• Pro. 300 actions a month, and the slower, more careful model for documents and for the panel.

What you have used is shown in the sidebar and on Home. When you reach the limit, Docmode says so, tells you when it resets, and offers both ways past it: upgrading, or using your own key. Nothing fails silently.

If you have an Anthropic API key of your own, you can put it in settings and your usage stops being counted at all. It works on both plans. Plans and limits explains both routes.

What gets sent, and what does not

Nothing is sent anywhere until you ask for something. When you do, the text the request needs, the passage you selected or the document you asked about, goes to Anthropic to produce the answer, and comes back.

Your writing is not used to train AI models. The security page is the fuller answer.
