Cursor

A smart code editor based on secondary development of VS Code, with "native built-in AI" as its core selling point. It does not rely on plugins but deeply integrates AI into the underlying architecture of the editor, enabling it to understand the context of the entire project's codebase. It also supports seamless migration of all VS Code configurations and plugins.

Google Antigravity

Antigravity supports multiple models, including Gemini 3 Pro, Claude Sonnet 4.5, and GPT-OSS, allowing developers to select the most suitable model for their tasks within the same environment.

Codex

OpenAI Codex is an AI programming model and assistant developed by OpenAI, capable of translating natural language instructions into corresponding source code. It provides developers with intelligent code completion and code generation functionalities. Initially launched in 2021 as the code model for the OpenAI API, it once served as the core engine for GitHub Copilot. With the evolution of OpenAI's technology, Codex returned in 2025 in a new form as an "AI programming agent," capable of understanding complex requirements and automatically writing and debugging code, significantly enhancing development efficiency and software delivery speed.

Kiro

Kiro is an AI-powered programming IDE launched by AWS, which adopts a specification-driven development model. It transforms natural language requirements into clear specification documents and tasks, then uses built-in AI agents to generate code, debug, and optimize, providing comprehensive assistance throughout the development process of large-scale projects.

Trae

Trae (official website: trae.ai) is an AI-native integrated development environment (IDE) launched by ByteDance. It is not merely a programming assistant but rather a "collaborative partner" that deeply integrates large language models (LLMs) to help developers achieve more intelligent and automated software development—from requirements analysis and code construction to debugging and deployment.

Claude

Claude is an intelligent language interaction platform developed by the American AI company Anthropic. It integrates capabilities such as deep text understanding, information organization, code assistance, and task analysis, enabling it to handle more complex tasks beyond simple chat conversations. These include long-text summarization, image analysis, logical reasoning, and programming assistance, among others. Compared to some single-purpose Q&A bots, Claude functions more like an intelligent tool equipped with reasoning logic and scalable features.

Completely resolve the language issues in Google Antigravity responses.

Google Antigravity performs excellently in scenarios such as task planning, application generation, and code building, but many users face a common frustration: even when they intend to output content in a specific language, Antigravity often automatically switches back to English. Whether it's task plans, execution strategies, application copy, or final outputs, the issue of "default English output" frequently arises, affecting the user experience.
