Web Demo

IDE Plugins

Your browser does not support the video tag.

Next-Generation AI Coding Tool

Provides support at every stage of programming through capabilities like code completion, code suggestions, and test case generation.

Code Auto-Completion

Intelligently predicts and provides auto-completion suggestions based on the current code context, enabling faster coding while reducing manual input time and errors.

Intelligent Chat

You can ask questions or make requests to Fitten Code, which can provide answers or directly generate the code you need.

Unit Test Generation

Automatically generates unit test cases for the selected code, supporting various unit testing frameworks.

Code Optimization

Automatically detects potential issues in the code and optimizes its structure, helping to enhance code readability and maintainability.

Comment Generation

Analyzes the structure and functionality of the code, identifies the deeper meanings of code blocks, and generates clear and concise comments.

Online Search

Can search the internet for information that helps answer your questions and provide responses based on the retrieved information.

Coding Agent

The Coding agent can call appropriate tools (such as “modify file”, “execute command”, “search file”, “read file”, etc.) based on task requirements. It actively acquires and understands the background information of the tasks and simultaneously analyzes and formulates the optimal solution. Through an iterative execution process, the agent can break down complex problems and execute them step by step, achieving efficient and precise task handling, thereby enhancing the intelligence level of automated programming.
