# Chat

> Use AI Agents and Workforces in a chat interface on desktop, mobile, and browser

<img src="https://mintcdn.com/relevanceai/A_21bclrTUCd6PDj/images/hero-chat.png?fit=max&auto=format&n=A_21bclrTUCd6PDj&q=85&s=4e66ed362b15e6a5a6e0eb7680bf149d" alt="Relevance Chat" width="2408" height="1660" data-path="images/hero-chat.png" />

Chat is where you interact with your AI Agents and Workforces. @ mention any Agent, combine multiple Agents in one conversation, or use pre-built Agents for tasks like generating images, deep research, and building slides — all from [chat.relevanceai.com](https://chat.relevanceai.com), on desktop and mobile.

Once you build an Agent or clone one from the Marketplace, you can use it in Chat — and [control which Agents are visible](/get-started/chat/using-agents#agent-visibility) to your team.

## Getting started

Navigate to [chat.relevanceai.com](https://chat.relevanceai.com) to start chatting. Chat works on desktop and mobile browsers, and is also available as a desktop app.

### Selecting an LLM

You can choose which LLM to use for your conversation, or select **Auto** to let Chat pick the best model for your request.

<div style={{ width: '100%', position: 'relative', paddingTop: '56.25%' }}>
  <iframe src="https://app.supademo.com/embed/cmfgfi5x0bz4239ozw2fj4het" frameBorder="0" title="How to select an LLM in Chat" allow="clipboard-write; fullscreen" webkitAllowFullscreen="true" mozAllowFullscreen="true" allowFullscreen style={{ position: 'absolute', top: 0, left: 0, width: '100%', height: '100%', border: '3px solid #5E43CE', borderRadius: '10px' }} />
</div>

Once you've selected your model, you can [run Agents and Workforces](/get-started/chat/using-agents) in your Chat conversations.

## Supported file types

Upload documents, images, and data files to give your conversations context, or generate new files from Agent responses. The following extensions are fully supported — other file types can still be uploaded but may not be processed reliably.

<Tip>
  Chat can preview 70+ file types directly in the conversation. Pasting from clipboard is limited to images only.

## Frequently asked questions (FAQs)

<AccordionGroup>
  <Accordion title="How does Chat usage affect my credits?">
    Chat credit usage will show up in the **Plan & Billing** credit monitoring section as **'Chat Orchestrator'**.

    You'll be charged credits based on:

    * The LLM model you're using in Chat
    * How much you use Chat (number of messages and interactions)

    Built-in agents like [Slide Builder](/get-started/chat/slide-builder) will also appear on this page when you use them in Chat.

    <Info>
      To monitor your Chat credit usage, navigate to **Settings > Plan & Billing** to see a detailed breakdown of your credit expenses. Learn more about [Plans and credits](/admin/subscriptions/plans).
    </Info>
  </Accordion>

  <Accordion title="Can I use different LLMs in Chat?">
    Yes, you can select the LLM you want to use in Chat by following these steps:

    1. Click on the cog icon in the top right of your screen
    2. Choose the 'Chat Model' on the pop-up that appears

    You can also add to the System Prompt for your Chat from this screen.
  </Accordion>

  <Accordion title="Can I use Relevance Chat on mobile?">
    Yes! While the main Relevance AI platform ([app.relevanceai.com](https://app.relevanceai.com)) is not available on mobile devices, you can use Relevance Chat by visiting [chat.relevanceai.com](https://chat.relevanceai.com) in a browser on your mobile device.

    A dedicated Relevance Chat mobile app is also on the way!
  </Accordion>

  <Accordion title="Can Chat remember my previous conversations?">
    Yes! Chat Memory allows Relevance Chat to remember and reference your recent conversations. You can ask questions like "What did I ask about earlier?" or "Who did I compare X against recently?" and get contextual answers based on your chat history.

    **Important limitations:** Chat Memory only remembers history within the same project, and you can only access your own chat history, not other users' conversations in the same project. This is different from Agent memory, which is conversation-specific memory within individual Agent interactions.
  </Accordion>

  <Accordion title="How do I switch between projects in Chat?">
    You can switch between projects using the project selector in the bottom left of the Chat interface. You can also use **Cmd + K** (Mac) or **Ctrl + K** (Windows) for quick access. When you switch projects, you'll have access to all agents available in that project.

    For more details, see [Learn how to switch projects in Chat](/admin/project-management/switch-projects#switching-projects-in-chat).
  </Accordion>

  <Accordion title="What are Edge regions and how do I select them?">
    Edge regions (US Edge, AU Edge, and EU Edge) are available in the Chat browser extension and desktop app. If your project is in an Edge region, it will appear in the project switcher labeled with **(Edge)** — for example, **US (Edge)**.

    To select an Edge region project, open the project switcher and look for the **(Edge)** label next to the region name. For detailed instructions, see [how to switch projects in Chat](/admin/project-management/switch-projects#selecting-an-edge-region-in-chat).
  </Accordion>

  <Accordion title="What keyboard shortcuts are available in Chat?">
    Chat supports the following keyboard shortcuts:

    | Action                           | Mac    | Windows |
    | -------------------------------- | ------ | ------- |
    | Toggle left panel (chat history) | Cmd+\\ | Ctrl+\\ |
    | Toggle right panel (Super GTM)   | Cmd+B  | Ctrl+B  |
    | Switch projects                  | Cmd+K  | Ctrl+K  |
  </Accordion>

  <Accordion title="Which Agents will show up in Chat - all the Agents in my organization, or just the ones in a specific project?">You'll be able to select the project you want to use Chat on in the bottom left. You'll be able to use all of the Agents you have access to in this project. If you want to access Agents in another project, you'll need to switch to that project in the bottom left.</Accordion>
  <Accordion title="Can I call multiple Workforces in the same Chat?">Not at this time, but we hope to add this feature soon!</Accordion>
  <Accordion title="Can I call a Workforce and an Agent in the same Chat?">Not at this time, but we hope to add this feature soon!</Accordion>
