Meet CWC

A community-driven, non-agentic coding tool for AI-assisted programming created by an independent developer.

🧩 Built for VS Code and its derivatives (Cursor, Windsurf, VSCodium, etc.)
✌️ 100% free and open source!

Guiding Principles:

• initialize popular chatbots—don't scrape responses
• API tools—battle-tested must-haves
• respect privacy—zero tracking
• lightweight—about ~1MB of code

CWC is for you if:

• you're an experienced engineer working on a large codebase
• you're a student or hobbyist who thrives on the intricate aspects of coding
• you love open source software! 🫶

See how simple it is to implement a feature with ChatGPT:

Workflow with CWC is simple and effective:

Context selection

Coding agents are designed to offload the burden of relevant context selection from the programmer. With today's advancements in LLMs capabilities, the technology is dramatically accelerating the pace a new code is created. For some it is too fast too keep up though. Over time, they lose confidence in their knowledge of the codebase they work on. Verifying AI-suggested changes becomes challenging, and bugs or unintended behaviors slip in more easily than ever.

CWC does not prompt-engineer any form of autonomous AI assistance, instead, it expects programmer to be constantly in the loop with the evolving codebase by requiring careful context selection.

This friction rewards in:

• building mental model of the codebase,
• zero idle time waiting for the AI to figure things out,
• speed, quality and cost efficiency of AI-assistance.

Chatbot initialization

Code with your favorite chatbot without tedious copy-pasting and apply responses with a single click.

The open source browser extension bridges your editor and the browser. Available for all Chrome and Firefox based browsers.

• Chrome Web Store
• Firefox Add-ons

AI Studio • ChatGPT • Claude • DeepSeek • Doubao • Gemini • Grok • HuggingChat • Mistral • Open WebUI • OpenRouter Chat • Qwen • Yuanbao

Legal Disclaimer: After chat initialization, the extension does not read the incoming message. The injected Apply response button is not a means of automatic output extraction, it's an alias for the original copy to clipboard button.
