# Chat with Code Assistant in SourceCraft

<!-- source: en/_includes/sourcecraft/disable-ai-features-note.md -->
{% note warning %}

SourceCraft uses the capabilities of AI models within Yandex. For this to work, some of your [organization's](https://sourcecraft.dev/portal/docs/en/sourcecraft/concepts/index.md#org) data needs to be sent to Yandex.

In private organizations, you can [disable](https://sourcecraft.dev/portal/docs/en/sourcecraft/operations/disable-ai-features.md) data transfers to Yandex, but this will limit [Code Assistant](https://sourcecraft.dev/portal/docs/en/sourcecraft/concepts/code-assistant.md)'s capabilities.

<!-- source: en/_includes/sourcecraft/ai-chat-description.md -->
The SourceCraft interface has a built-in chat with Code Assistant you can use to interact with the AI assistant.

The following scenarios are supported:
* SourceCraft user help, FAQ.
* Searching through the documentation.
* Generating code snippets.
* Explaining code in project files or individual file sections, including code in [markdown](https://en.wikipedia.org/wiki/Markdown) syntax intended for documentation.
* Help with debugging and troubleshooting.
* Generating tests for your code.
* Generating documentation.
* Scanning code for potential issues.
* Suggesting improvements and alternative solutions.
* Generating charts.
* Writing commit messages.

The page in the SourceCraft interface you view defines the context for Code Assistant, e.g., [repository](https://sourcecraft.dev/portal/docs/en/sourcecraft/concepts/index.md#repos) files, current open file, [pull request](https://sourcecraft.dev/portal/docs/en/sourcecraft/concepts/index.md#pr) or [issue](https://sourcecraft.dev/portal/docs/en/sourcecraft/concepts/index.md#issues) content, etc.
