SourceCraft Code Assistant overview
Warning
SourceCraft uses the capabilities of AI models within Yandex. For this to work, some of your organization's data needs to be sent to Yandex. For more information, see the terms of use.
Code Assistant is an AI-driven developer assistant based on large language models (LLM)s. With Code Assistant, you can optimize the code writing process and increase your performance.
The smart autocompletion mode enables AI assistant to analyze the code context and come up with the most relevant suggestions for functions, cycles, conditions, and more.
Code Assistant also features a chat mode you can use to interact with the AI assistant in SourceCraft or your IDE interface.
SourceCraft Code Assistant terms of use
The Code Assistant plugin is now available for Visual Studio Code, VSCodium, and JetBrains IDE versions 2025.2, 2025.1, 2024.3, 2024.2, and 2024.1.
Note
To work with Code Assistant, you will need continuous internet access.
The code analysis is running using the SourceCraft computing resources, which means Code Assistant does not generate any load against the user workstations.
LLMs that are used in Code Assistant have been fine-tuned based on the open-source code corpus. The quality and number of autocompletion prompts depends on the amount and diversity of open-source code in a particular language.
Code autocompletion
The smart autocompletion mode explicitly supports code autocompletion for the following programming languages and frameworks:
- C++
- Go
- Java
- JavaScript/TypeScript
- Kotlin
- Python
- Scala
- SQL
- Swift
Autocompletion may also work for other languages. For languages that are less represented in public repositories, the number and quality of autocompletion prompts will be lower.
Code Assistant analyzes your code context and provides the following types of suggestions:
- Automatic.
- User-triggered (Ctrl + Space). In Visual Studio Code, you can also use Ctrl + Enter.
Code Assistant supports the following types of suggestions:
- Inline completion: Provides completion suggestions as you type. Works for code, texts, and documents.
- Full-function completion: Provides autocompletion for entire functions or methods.
For more information about autocompletion, see Code autocompletion in SourceCraft Code Assistant.
When generating a suggestion, the loading icon will appear to the left of the editable code. If generation stops or there is no result, you will see the (no suggestion) icon.
The suggestion indicator is enabled by default.
For more information on managing the suggestion indicator, see Suggestion indicator.
Chat mode and agent mode
Visual Studio Code has an agent mode helping you fine-tune tools, connect various LLMs, MCP servers, select operating modes, and more.
The JetBrains IDE features a chat mode providing an AI assistant with customizable context.
Quick actions
For your convenience with the plugin, there are quick actions, i.e., Code Assistant integrations with your IDE.
The following integrations are available for Visual Studio Code:
- Lightbulb: Menu you access by clicking next to the code blocks and can use to generate docs and tests.
- CodeLens: Buttons above the code blocks you can use to generate docs and tests and set up actions displayed in codelenses and lightbulbs.
- Context menu: Right-click menu you can use to generate docs and tests, send selected code to the chat, request code autocompletion/improvements, or generate a commit message in the Git version control system.
- Slash (/) commands: You can use the Slash Commands selector in the chat toolbar to request text generation or code improvement for the file opened in the editor, generate a commit message in the git version control system, and invoke AI code review.
For JetBrains IDEs, there are codelenses that can generate docs and tests.
