# Quickstart

Install Sesori on iPhone or Android, connect your computer, and run your first local AI coding session.

This guide takes you from app installation to a real AI coding session on iPhone or Android. The assistant and repository run on your computer; your phone controls the session through Sesori.

You need the Sesori Bridge on the computer that holds your code, the Sesori app on your phone, and at least one supported AI coding assistant.

{% hint style="info" %}
New to the terminal? Installing and starting the Bridge requires a few commands. If you get stuck, [email us](mailto:contact@sesori.com).
{% endhint %}

## 1. Install the app

* **iOS:** [Download from the App Store](https://apps.apple.com/app/sesori/id6760642500)
* **Android:** [Download from Google Play](https://play.google.com/store/apps/details?id=com.sesori.app)

Open the app and sign in. Use the same Sesori account when you start the Bridge.

More details: [Install the app](/setup/install-the-app.md)

## 2. Install, configure, and run the Bridge

Follow [Install, configure, and run the Bridge](/setup/set-up-the-bridge.md#1-install-the-bridge). That page provides the official convenience commands, their trust implications, and an inspect-before-running alternative.

```bash
sesori-bridge
```

Choose a sign-in method. GitHub, Google, and Apple authentication open or print a browser URL; email authentication continues in the terminal.

Keep this process running while you use Sesori. The Bridge connects your phone to the assistants and projects on this computer.

More details: [Install, configure, and run the Bridge](/setup/set-up-the-bridge.md)

## 3. Connect the app and Bridge

The app and Bridge pair automatically when both use the **same Sesori account**. Confirm that the Bridge indicator in the app turns green.

More details: [Connect the app and Bridge](/setup/connect-the-app.md)

## 4. Choose an AI coding assistant

In Sesori, open **Settings → Harnesses** and choose one of these assistants. Each name links to its current setup and limitations:

* [OpenCode](/setup/choose-a-harness.md#opencode)
* [Codex](/setup/choose-a-harness.md#codex)
* [GitHub Copilot CLI](/setup/choose-a-harness.md#github-copilot)
* [Cursor](/setup/choose-a-harness.md#cursor)
* [Claude Code](/setup/choose-a-harness.md#claude-code)
* [Hermes Agent](/setup/choose-a-harness.md#hermes-agent)
* [Pi](/setup/choose-a-harness.md#pi)
* [Oh My Pi (OMP)](/setup/choose-a-harness.md#oh-my-pi)
* [DeepSeek Harness](/setup/choose-a-harness.md#deepseek)
* [Grok Build](/setup/choose-a-harness.md#grok-build)

Start with an assistant you already use when possible. If you are choosing a new one, compare managed installation, host-platform support, authentication, and permission behavior before installing it. Harnesses do not expose identical controls through Sesori.

Use **Install runtime** when Sesori offers it. Otherwise, follow the assistant's official installation and authentication guide, then refresh its status in Sesori. The [harness chooser](/setup/choose-a-harness.md) compares platforms, official setup links, and safety behavior.

## 5. Create your first session

1. Open a project. If none appears, use **Add Project** to select a folder on your computer.
2. Tap **New session**.
3. Select a **Coding tool** and any available model or agent options.
4. Send a prompt.

The controls inside the session depend on what the selected assistant supports.

For a low-risk connection check, send: `Summarize this project and identify its test command. Do not change files.` Once the response streams correctly, try a small edit and [review the local changes](/user-guide/reviewing-changes.md) before you commit anything.
