VS Code AI Chat Extensions

Ranking updated Jun 30, 2026

For an AI chat extension for VS Code, the first results are kodu-ai/claude-coder, microsoft/vscode-copilot-chat and huggingface/chat-ui (Chat UI is a web-based LLM chat interface and orchestration gateway, not a VS Code extension — it does not integrate into the editor for codebase-aware conversations or inline code editing). yishentu/claudian and chatgptnextweb/nextchat round out the shortlist. Compare the match explanations and check the project documentation against your requirements.

These extensions integrate conversational artificial intelligence directly into your editor to analyze and refactor code.
