# Web and desktop apps

> Use Mantle in a browser or install the macOS app for native notifications and local coding agents.

Mantle runs fully in a web browser on desktop and mobile devices. A native app is also available for macOS.

Windows, Linux, iOS, and Android native apps are planned. Until they are released, use the web app on those platforms.

## Install the macOS app

<Steps>
  <Step title="Open the download page">
    Go to [mantle.chat/downloads](https://mantle.chat/downloads). Mantle supports Apple Silicon and Intel Macs running
    macOS 12 or later.
  </Step>

  <Step title="Choose the correct download">
    Most recent Macs use Apple Silicon. Choose the Intel build only if your Mac has an Intel processor.
  </Step>

  <Step title="Open Mantle and sign in">
    Follow the macOS install prompt, then sign in with the same Mantle account.
  </Step>

  <Step title="Allow notifications">
    Allow notifications if you want mentions, replies, and direct messages in Notification Center.
  </Step>
</Steps>

The app checks for updates and lets you restart when you are ready to install one. Mantle's macOS builds are signed and
notarized by Apple.

## Use a supported local coding agent

The macOS app can use supported coding tools installed on your Mac, including Codex, Claude Code, Cursor, OpenCode, and
Grok CLI. You sign in through the coding tool's official provider flow, and that provider's terms and usage rules
continue to apply.

<Steps>
  <Step title="Install and sign in to the coding tool">
    Follow that tool's own setup and official sign-in instructions on your Mac.
  </Step>

  <Step title="Open local provider settings">In the macOS app, go to **Settings → Models → Local providers**.</Step>

  <Step title="Choose the provider">
    Mantle checks whether the tool is installed and signed in. Follow the on-screen setup if it needs a path or login.
  </Step>

  <Step title="Enable it and choose a model">
    Once ready, turn the provider on. Its available models appear in Mantle's model picker.
  </Step>
</Steps>

Local providers run on your Mac and are available only while the desktop environment can run them. They may have their
own usage limits and permissions. Mantle-hosted AI uses Mantle credits; a local coding agent follows its provider's
rules instead.

<Note>
  Local-provider availability and model names depend on the installed tool and your account with that provider. Check
  the status shown in Mantle settings when a model is missing.
