# Getting started with SourceCraft Code Assistant
{% 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. For more information, see the [terms of use](https://yandex.com/legal/cloud_terms_code_assistant).
{% endnote %}
Code Assistant is an AI-driven developer assistant based on [large language models (LLM)s](https://en.wikipedia.org/wiki/Large_language_model). With Code Assistant, you can optimize the code writing process and increase your performance.
The [smart autocompletion](https://sourcecraft.dev/portal/docs/en/code-assistant/concepts/index.md#autocompletion) mode enables the AI assistant to analyze the code context and come up with the most relevant suggestions for functions, cycles, conditions, and other elements.
Code Assistant also features a [chat mode](https://sourcecraft.dev/portal/docs/en/code-assistant/concepts/index.md#chat) you can use to interact with the AI assistant in the SourceCraft interface, your IDE, or [SourceCraft CLI with built-in OpenCode](https://sourcecraft.dev/portal/docs/en/sourcecraft/operations/cli-quickstart.md).

{% endnote %}
{% endlist %}
## Test the plugin {#work-with-plugin}
{% note info %}
To work with Code Assistant, you will need continuous internet access.
{% endnote %}
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.
## Use case {#examples}
In this example, we use the [_insert_](#insert) mode to revise the code, and then, the [_replace_](#replace) mode, which provides suggestions for the next lines based on the edits we made:
Here, after we have changed the argument name, the _replace_ mode updates it accordingly in the other lines:
## Insert mode {#insert}
The _insert_ mode in Code Assistant can suggest the most suitable options to complete the current line or word.
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**.
1. Open the IDE and create a test file named `server.cpp` with the following contents:
```cpp
// simple web-server to work with sockets
#include
#include
#include
#include
#include
using namespace std;
int main() {
}
```
1. In the `int main()` section, start typing something, e.g., `//create socket`. See the Code Assistant suggestion:
```cpp
...
int main() {
//create socket
int sockfd = socket(AF_INET, SOCK_STREAM, 0);
}
```
1. Select an action for the suggestion:
{% list tabs group=ide %}
- Visual Studio Code {#vscode}
* Click **Tab** to accept the suggestion.
* To start accepting the suggestion word by word, press **Ctrl** + **→** for Windows or Linux or **Command** + **→** for macOS.
* To discard the suggestion, press **Esc**.
* If there are multiple suggestions, you can switch between them using **Alt** + **[** and **Alt** + **]** for Windows or Linux or **Option** + **[** and **Option** + **]** for macOS.
- JetBrains IDE {#jb}
* Click **Tab** to accept the suggestion.
* To discard the suggestion, press **Esc**.
{% endlist %}
You can also watch our Code Assistant video tutorial [here](https://sourcecraft.dev/portal/code-assistant/).
## Replace mode {#replace}
The _replace_ mode in Code Assistant can suggest corrections and renaming options in the current file code based on the changes you have made.
1. Open the IDE and create a test file named `fibonacci.py` with the following contents:
```py
def fibonacci(k):
if k == 0:
return 0
elif k == 1:
return 1
else:
return fibonacci(k-1) + fibonacci(k-2)
print(fibonacci(10))
```
1. For example, change the variable name from `k` to `n`. See the Code Assistant corrections:
```py
def fibonacci(n):
if n == 0:
return 0
elif n == 1:
return 1
else:
return fibonacci(n-1) + fibonacci(n-2)
print(fibonacci(10))
```
Code Assistant suggests corrections line by line. Move the cursor to the relevant line to see a correction from Code Assistant.
1. Select what to do with the suggestion:
* Click **Tab** to accept the suggestion.
* To discard the suggestion, press **Esc**.
The model takes code revision history into account. Depending on this history, the suggestions may vary significantly.
Also test [quick actions](https://sourcecraft.dev/portal/docs/en/code-assistant/operations/quick-actions.md) and the plugin's performance in [agent mode](https://sourcecraft.dev/portal/docs/en/code-assistant/operations/agent/chat-interface.md) in Visual Studio Code or [chat mode](https://sourcecraft.dev/portal/docs/en/code-assistant/operations/chat.md) in the JetBRains IDE.
