# Get started with MITHUNAI Chat

> Open chat.mithunai.com, sign in with your MITHUNAI account, start a thread, switch on your knowledge, pick a model and attach a file, in five minutes.

To start using MITHUNAI Chat, open `chat.mithunai.com`, sign in with the MITHUNAI account you already
use for the console, and type in the message box. There is no separate Chat account and nothing to
install. Switch on **Knowledge** in a thread when you want answers from your own content, with
citations.

## Before you start

* **A MITHUNAI account in your organisation.** Any role can use Chat. If you do not have one, ask an
  Owner or Administrator to [invite you](https://docs.mithunai.com/administration/invitations.md).
* **Knowledge to draw on**, if you want grounded answers: at least one [source](https://docs.mithunai.com/knowledge/sources.md)
  indexed and one [assistant](https://docs.mithunai.com/assistants/configure.md) that answers from it. Chat works without them,
  as a general chat workspace.

## Open Chat and sign in

**1. Open Chat**

Go to `chat.mithunai.com`, or choose **Chat** under **More in MITHUNAI** in the console's
sidebar. On a deployment of your own, Chat has its own address beside the console's.

**2. Sign in once**

Choose the sign-in button. Chat sends you to the MITHUNAI sign-in page, where you sign in as you
do for the console, and brings you back signed in.

**3. Check you are in**

The rail on the left shows your conversations, and its foot shows your name and email with **Log
out** beside them. An account from another organisation is refused with *This account is not a
member of the organisation this application belongs to.*

## Your first thread

1. **Type a message** in the box at the bottom and press **Enter**. A new thread starts and is named
   for you after the first reply.
2. **Switch on your knowledge.** Open **MCP Servers** under the message box and select
   **Knowledge**. From then on the model can list, search and ask your knowledge in this thread, and
   cite what it used. See [Ask questions grounded in your knowledge](https://docs.mithunai.com/chat/knowledge.md).
3. **Pick a model**, if you want a different one. The model menu at the top of the thread lists the
   models your organisation's Gateway offers. See [Choose a model](https://docs.mithunai.com/chat/models.md).
4. **Attach a file**, if the question is about one: plain text, Markdown, CSV, PDF, or a PNG, JPEG or
   WebP image, up to five files of 10 MB each and 25 MB in all.

> [!TIP]
>
> For a question that must be answered from your documentation, say so: "Using our knowledge, how do
> I rotate an API key?" The model then uses the Knowledge tool rather than its own general
> knowledge, and the reply cites the passages it used.
