# AI Chat Examples

> Things to ask the AI chat, grouped by what they show and what your model needs — each one tested against the demo vault.

Things to ask the [AI chat](https://docs.docgraph.app/ai/chat/), grouped by what they show. Every prompt here is written for the **demo vault** — the one-click sample vault the welcome screen offers (see [Your first vault](https://docs.docgraph.app/getting-started/first-vault/)) — so you can copy it into the message box (<kbd>⌘⇧L</kbd>) and get a real answer. AI has to be [set up](https://docs.docgraph.app/ai/setup/) first.

Each prompt is tested on the two models DocGraph suggests by default — Ministral 3B and Gemma 4 E2B — before it is listed here. Bigger models answer them too, usually in more detail.

## What your model needs

Most of these work with whichever model you picked. Each group below says what it needs, in one of four levels:

- **No model** — DocGraph does the work itself; the model isn't asked. AI still has to be set up, because the chat box stays off until it is.
- **Any model** — every model DocGraph offers can do it, including Apple's on-device model. Bigger models write better answers, and smaller ones may skip a table or a diagram you asked for.
- **Any model + Topic summaries** — the model plus summaries DocGraph writes in the background. On by default under **Settings → AI → Chat & index**; a new vault needs a few minutes before they're ready.
- **Agent on + tool calling** — turn on **Agent** in the chat. Apple's on-device model can't do this. A model with *tool calling* acts reliably — a **Tools** chip under the chat's header shows that yours can use them. Models without it fall back to a slower method that may get it wrong; the chat says so, and the Agent button shows ⚠.

## Find a note

**Needs:** no model. DocGraph answers these itself, before any model runs.

- **"Find the note about encryption"** — a card of matching notes with the reason each matched; when one is clearly ahead, it opens. Follow up with "open the second" to pick another from the card.

## Ask your notes

**Needs:** any model. Answers come from your pages, with sources you can click.

- **"How do backlinks work?"** — answered from the Backlinks and Linking Notes pages.
- **"How do I lock just one line of a note?"** — a how-to drawn from the Encryption page.
- **"Which file types can DocGraph open?"** — the File Types folder, summed up.

## Tasks and people

**Needs:** any model. Todos are ordinary text, so the chat reads them like everything else.

- **"What is @sam working on?"** — every task and mention for one person.
- **"What's blocking the launch?"** — the blocked items on Launch Checklist, with what each is waiting on.

## Connections

**Needs:** any model. The chat follows typed links, not just words.

- **"What depends on Linking Notes?"** — **Connections** under the answer shows each link it followed.

## Compare in a table

**Needs:** any model, though a small one may answer in plain text instead. Answers can hold tables, drawn right in the chat — and, with a larger model, diagrams and charts.

- **"Compare Plain Files Are Enough and A Database Is Better in a table."** — the two Debate pages side by side; **Insert table into note** keeps the table.

## Narrow it down

**Needs:** any model. DocGraph narrows the search itself; the model writes the answer. Name a tag or a person and the search narrows to match.

- **"Which notes are tagged #privacy?"** — only notes carrying that tag; a line above the answer says so.
- **"What does @priya want?"** — read from a sentence in Mentions and Dates, not from a task.

## Do things

**Needs:** Agent on + tool calling — except `/todo`, which needs no model. Every change shows a card first and waits for **Approve**; **↩ Undo last AI change** takes it back.

- `/todo call sam tomorrow 6pm` — DocGraph reads the date and the person itself and opens a task card.
- `/create a note called Reading List with three books about note-taking` — a new page, previewed before it's written.

## The whole vault

**Needs:** any model + Topic summaries. Until they're ready, the chat says so and answers from matching notes instead.

- **"What are the main themes of this vault?"** — answered from topics, groups of linked notes summarized in the background.

## About DocGraph

**Needs:** any model. Questions about the app are answered from this documentation, built into the app, marked **DOCS** under Sources.

- **"How do I export a note to PDF?"**
- **"What does ⌘K do?"**

## The page you're on

**Needs:** any model. Open a note first, then ask about "this page".

- **"Summarize this page"** — try it with the Linking Notes page open.
