Add Chat UI (Transcript UI)

Add a ready-made chat UI prefab to enable text input and conversation transcripts.

Introduction

Chat UI is optional, but it’s extremely useful for debugging, testing without voice, and demonstrating text-based conversations.

Prerequisites

• Convai SDK installed

• A scene with Convai setup

Step-by-step

1

Locate the Transcript UI prefab

• In the Project window search bar, search:

  • TranscriptUI_Chat

• Make sure your search scope includes In Packages or All.

• Alternatively, you can use the package path:

  • Packages/com.convai.convai-sdk-for-unity/Prefabs/TranscriptUI/TranscriptUI_Chat.prefab

2

Add the prefab to your scene

• Drag and drop TranscriptUI_Chat.prefab into the scene.

• Expected result: The UI appears in the Hierarchy and is visible in Game view (Play Mode).

3

Ensure an Event System exists

• If your scene does not have an EventSystem:

  • Right-click in Hierarchy → UI → Event System

• Expected result: An EventSystem exists and UI input works in Play Mode.

Troubleshooting

• UI doesn’t respond to clicks/typing

  • Confirm there is exactly one EventSystem in the scene.

• Prefab not found

  • Confirm the package is installed correctly.

  • Confirm your Project window search includes “In Packages” or “All”.

Conclusion

You’ve added the Transcript UI to your scene, enabling text input and readable conversation logs. You can now test conversations via keyboard or microphone.
