**On this device** is Streamliner for one person, with their own tools. There is no account and no sign-in, and nothing is stored on our servers. Your streamlines, your key and your chats live on this device; the assistant talks straight to Anthropic with your key, and straight to your MCP servers with your sign-ins.

Choose **Use on This iPhone (Free)** (on this iPad, on this Mac) on the first screen, or later under **Join an Organization…** (account switcher, or **Settings → Accounts**). In **Settings → Accounts** it reads *On this device · Free · nothing stored on our servers*.

## Getting started

You need two things:

1. **A model key.** Until you have one, **Add a Model Key** sits at the top of the list and opens the Vault. Pick the provider, paste your key (Anthropic: console.anthropic.com) and choose **Save**. See The Vault (FR-5).

2. **A streamline.** Ask the **Concierge**, which comes with the app, to set one up with you (FR-7); or open the **Library** and choose **New Streamline**, or **Import a File** if someone has shared one with you. See Making a streamline (FR-2) and Sharing and importing streamlines (FR-6).

Then use the streamline's **+** to start a chat, as in an organization.

## What is the same

Chats, the composer, quick phrases, cards, confirmation cards and sign-in cards all work as they do in an organization. You are your own organization: you decide which tools ask first, and the bill for the AI is yours, on your Anthropic account.

## What is different

- **You set everything up.** The streamline's instructions, its MCP servers, its model and its quick phrases are yours to edit in the **Library**. Choose **Edit in Library** from a streamline's menu (touch and hold its row, or right-click it on the Mac), or open the Library from the list.
- **Sign-ins are per server**, the first time a server asks. The Vault lists them under **Sign-ins**.
- **There is no relay, no budget and no usage page.** Anthropic's console shows what you spend. Give a streamline its own key to see its cost separately.
- **Secure forms** come only from your servers' own forms.

## Leaving

**Remove from Accounts**, in **Settings → Accounts**, takes *On this device* off your accounts. Nothing is deleted: your streamlines, keys and chats stay on this device, and **Use on This iPhone (Free)** brings it back.
