# How to use Chat

Chat is your general-purpose AI workspace - use it for anything from drafting emails and building content strategies to brainstorming ideas, getting advice, or analysing data.  
  
**1\. Open Chat:** Select **Chat** from the main navigation menu.

**2\. Choose Your Model and Persona:** Before starting, select the AI model and persona you'd like to use. These shape how the AI responds, so it's worth picking ones suited to your task.

**3\. Enter Your Prompt:** Type your prompt in the chat box and hit send. You can also click the **microphone icon** to use your voice instead of typing.

**4\. Explore Additional Options** Click the **+** icon at the bottom of the chat box to access more tools:

-   **Attach a file:** supports PDFs and CSVs
-   **Prompt Library:** insert a saved prompt to save time
-   **Thinking Level:** control how deeply the AI reasons through your request. Set it to **High** for complex tasks, **Low** for simple ones, or turn it off entirely for quick responses.
