# Features

## Chat

The chat interface is where everything happens. Ask a question, give an instruction, or describe what you want — Studio streams the AI's response in real time so you can see it think and act.

![Chat interface](/assets/studio-chat.59b1e87ba523d78abda6ad85bdbd253b32f0529f15b5ef99552fe9f1e76cafc9.5c07e18c.png)

What makes it powerful:

- **Extended thinking** — Expand the thinking panel to see the AI's reasoning before it responds. Useful for understanding complex analysis or debugging unexpected results.
- **Tool calls in real time** — Watch the AI execute queries, read files, and call APIs as it works. Every tool call is visible and expandable.
- **Voice input** — Dictate your messages instead of typing.
- **Auto-compact** — Long conversations don't hit a wall. When the context window fills up, Studio automatically summarizes earlier messages so the conversation continues seamlessly.


## Artifacts

When the AI generates something visual — a chart, a table, a code file, a document — it appears in the artifact panel alongside the chat.

![Artifact panel](/assets/studio-artifacts.654d1b3357ef2e9beeb737027ebb343182a911cb988a17adb9e3e51c20405047.5c07e18c.png)

| Type | Example |
|  --- | --- |
| **Chart** | Revenue trends, segment overlap visualizations, funnel analysis |
| **Table** | Query results, user lists, segment previews |
| **Code** | SQL queries, YAML configs, workflow definitions |
| **Document** | Analysis reports, documentation drafts |


Artifacts are interactive. You can sort tables, zoom into charts, copy code blocks, and export anything to a file.

## Marketing Preview

![Marketing preview](/assets/studio-marketing-preview.2c7af734c09c9e815c6641a24dda7ba25ba1fc6184fe4f805dc7287091f93d40.5c07e18c.png)

Studio can render visual previews of your CDP resources directly in the artifact panel. When you build or review a journey, segment, or workflow, Studio generates an interactive diagram showing the full structure — entry criteria, decision points, segment rules, activation steps — so you can verify the logic before pushing to your account.

Ask the AI to modify a step and the preview updates in real time.

## Projects

Every time you start a new analysis or workflow, you end up re-explaining context: which database, which segment, what coding conventions to follow. Projects eliminate that.

![Project settings](/assets/studio-project-settings.726f593f08dff9b9846c7484d4a74f048c364fb5fae67a7b9d6c79534c074f56.5c07e18c.png)

A project is a saved workspace that pre-loads context into every new chat:

- **Instructions** — "Always use the `marketing` database. Format SQL with CTEs." Custom rules the AI follows automatically.
- **Working folder** — A directory on your machine where the AI reads and writes files (YAML configs, exports, query results).
- **Skills** — Pre-activate specific skills so they're always available. A "CDP Management" project might always have segment and journey skills enabled.
- **TD context** — Pin a default database, table, or segment so you don't have to specify it every time.


Switching Projects
Use `Cmd+P` or type `@project:` in the chat input or command palette to switch projects. Each project keeps its own configuration, so you can jump between "Analytics" and "CDP Ops" without reconfiguring anything.

## Slash Commands

Type `/` in the chat to invoke a skill directly. An autocomplete dropdown shows available skills — select one and it runs with your message as input.

![Slash commands](/assets/studio-slash-commands.2ff57f616ffd6361e003f42898be0b72dda1494d9cfbd0e48b129a752c01c058.5c07e18c.png)

For example, `/sql-skills:trino-optimizer` followed by a query will analyze it for performance issues and suggest improvements.

## Bang Commands

Type `!` to run any tdx CLI command or MCP tool directly from the chat. The output appears inline.

![Bang commands](/assets/studio-bang-commands.4c12846ce3cfff536da9a863605482d74afcda29093a7cbcb16b3af658d60a4d.5c07e18c.png)


```
!tdx databases
!tdx query "SELECT count(*) FROM mydb.users"
!tdx segment list
```

This is useful when you want quick, direct access to CLI functionality without going through the AI.
