# Work with the assistant

Send requests with images, files or picked elements, plan big changes first, answer questions, and stop, continue or rewind a turn.

![A change request typed in the chat, the assistant building and checking it in the preview, then the habit screen with a bigger calendar and Rewind on the finished turn](https://fluxnative.app/guide-media/work-with-the-assistant.50cb0c49.webp)

Name the screen and the result; the assistant builds, checks the preview, and leaves Rewind on the turn.

## Steps

1. Pick the agent from the menu at the top of the chat, or keep **Designer**.
2. Name the screen and the outcome; attach images, files, code lines or preview elements.
3. For a bigger change, pick **Plan** and approve its steps and credit range (about 20–60 credits on Standard for a plan that changes one file), or **Revise**.
4. Answer its questions while the turn runs; a question expires when the turn ends.
5. **Stop** keeps the edits that landed, **Continue** picks up the rest, **Rewind** undoes the latest turn.

## Agents

| Agent | For | Plans |
| --- | --- | --- |
| **Designer** (default) | Screens, features and the look | Every plan |
| **Build** | Builds, build errors and store review | Every plan |
| **Growth** | Launch plans, push campaigns, listing copy, video ads and metrics; usually 3–15 credits a message | Pro and up; one free turn per app on Creator |

Manage App's **Growth plan** shows on every plan, with no credits: your app's own facts, **Apps like yours**, **Growth loops** (**Add** briefs Designer on one not found yet) and **Moments ahead**. Growth writes the plan and the **Launch kit**; **Campaign links** start on Creator.

## Attach context

| What | Limit |
| --- | --- |
| Images (PNG, JPEG, WebP, GIF): paste, drop or the image button | 4 per message |
| Files: the file button | 6 files, 512 KB in total |
| Code: highlight lines in **Code** | The selection |
| Preview elements: the pick button, Shift-click for more | 5 per message |
| A Figma design: **Import from Figma** (the dashboard's **+** menu, or the Figma button in an app's chat), with the plugin | 12 screens per import on Free, 60 on paid plans. See [Build from a Figma design](https://fluxnative.app/docs/figma) |

## Good to know

- Big requests keep a checklist, one line an item: tap an item to see how it is checked. A done item's mark says what proves it (hover it to read, for example, that the assistant tried it in the preview); the line under the list names what only a phone shows (open the share link on it; notifications, the share sheet and haptics need an installed build); open items say why, once in the heading when they share a reason (**Not checked yet**, **Paused for credits**).
- Checks the assistant left failing are never yours to supply: the card reads **Not finished: checks still fail**, and **Fix it** starts a turn that fixes them.
- A chip to connect a backend or RevenueCat opens **Server** on its form, never a paid turn. A control the assistant points you to, such as **Server**, keeps an **Open** button under its reply.
- Credits a rewound turn used are not refunded. **New chat** (+) keeps topics apart; the plan sets how many run at once (1 on Free, 2 on Creator, 4 on Pro, 10 on Business), and when two change the same lines the later one asks which to keep.
- The floating assistant (⌘J) answers and opens pages but never edits code: it hands changes to the coding agent once you approve its card.

**Warning:** Never paste API keys, tokens or passwords into chat. Add them under **Server**.
