# Study modes

> Research-platform modes (voice, chat, video, concept test) explained.

The User Intuition MCP server supports multiple study modes for AI-moderated interviews.

## Research-platform modes

For live AI-moderated interview studies, mode is expressed as flags on the
study record rather than a separate field. See the
[Study-creation playbook](/mcp-server/guides/playbook) for full flag semantics.

| Mode            | `enable_chat` | `enable_video_recording` | Notes                                |
| --------------- | :-----------: | :----------------------: | ------------------------------------ |
| Voice (default) |    `false`    |          `false`         | Audio interview, no video            |
| Chat            |     `true`    |          `false`         | Text-chat interview                  |
| Video           |    `false`    |          `true`          | Voice interview with video recording |
| Chat + video    |     `true`    |          `true`          | Chat interview with video recording  |

Both flags default to `false`. You can combine them freely.

## Concept tests

Concept tests are a special study variant available in both voice and chat modes.

1. Set `is_concept_test: true` on the study when calling `create_study` or
   `update_study`.
2. Use `upload_concept_link` to attach concept material (a URL, mockup, or prototype
   link). The tool deduplicates by label, so re-uploading the same label updates the
   URL in place rather than creating a duplicate entry.
3. Remove a concept link with `delete_concept_link` by passing its `id`.

Before creating a concept-test study, load the matching prompt from the server:

| Study variant      | Prompt to use                        |
| ------------------ | ------------------------------------ |
| Voice concept test | `concept_test_planning_context`      |
| Chat concept test  | `concept_test_chat_planning_context` |

See the [Prompts](/mcp-server/prompts) page for the full prompt reference.
