# Test Chat Interface

> Test your assistant with a text-based chat interface for rapid iteration

The Test Chat interface provides a quick way to test your Famulor assistant's conversation flow without making actual phone calls.

## Accessing Test Chat

1. Navigate to your assistant's page
2. Click the **"Test Assistant"** button with the chat icon
3. A chat interface opens in a slide-over panel

## How It Works

The Test Chat interface simulates a conversation with your assistant:

* **Text-based interaction:** Type messages instead of speaking
* **Real AI responses:** Your assistant processes messages using the same logic as phone calls
* **Variable testing:** Test how your assistant handles variables and data collection
* **Tool execution:** See how your assistant uses configured tools and functions
* **Fast iteration:** Quickly test prompt changes without phone calls

## When to Use Test Chat

**Ideal for:**

* Testing conversation flow and logic
* Verifying prompt behavior and responses
* Debugging variable collection
* Testing tool/function calls
* Rapid prompt iteration

**Not suitable for:**

* Testing voice quality or speech recognition
* Testing call transfers (use phone testing)
* Testing phone-specific features
* Evaluating conversation timing and pacing

## Testing Workflow

**1. Test the conversation flow with the chat interface:**

* Verify your assistant understands user intents
* Check that variables are collected correctly
* Ensure tools execute as expected
* Validate response quality

**2. Test voice quality with a Web Call:**

* Verify voice clarity and tone
* Check response timing and pacing
* Test interruption handling

**3. Final testing with a Phone Call:**

* Test all features including call transfers
* Verify real-world call quality
* Test edge cases and error handling

<Note>
  Test Chat creates conversation records that appear in your [Chat list](/en/platform/chat-list), helping you review and analyze test sessions.
</Note>

## Cost Considerations

Test Chat interactions:

* Use AI processing credits from your account balance
* Are typically more cost-effective than phone testing
* Allow for faster iteration with immediate feedback
* Create conversation records for later review

<Tip>
  Use Test Chat for initial prompt development, then move to phone testing for final validation before deploying to production.
