Meet CWC

100% free and open source VS Code extension for AI-assisted programming. CWC treats the AI model less like a teammate and more like a calculator; by emphasizing context management, it modifies it predictably, accurately, quickly, thus cost-efficiently. Enjoy a modern software development workflow with a tool that doesn't try hard to replace You.

⚡️ World's fastest AI coding - one-shot tasks in a single chat or API call
🧩 Compatible with VS Code derivatives (Cursor, Windsurf, VSCodium, etc.)
🙋 Created by an independent developer
☕️ Backed by voluntary donations

Guiding principles:

• initialize chatbots—don't scrape responses
• univarsal—enable any workflow
• privacy first—zero telemetry
• 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 on a budget
• you believe software should be crafted, not generated

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

Workflow with CWC is simple and effective:

Context selection

With today's advancements in LLMs capabilities, the technology is dramatically accelerating the pace a new code is created through the work of automated agents. For some it is too fast too keep up though. Over time, they lose confidence in their understanding of the codebase they work on - verifying changes becomes challenging, making it easier for bugs or unintended behaviors to slip in.

CWC does not prompt-engineer any form of autonomous coding, instead, it expects programmer to be in the loop with the evolving codebase by manual context management.

The benefits of this friction include:

• developing a mental model of the codebase,
• quick results from a single chat or API call,
• predictable outputs.

Chatbot initialization

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

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

• Chrome Web Store
• Firefox Add-ons

Supported chatbots

AI Studio • ChatGPT • Claude • DeepSeek • Doubao • Gemini • Grok • HuggingChat • Mistral • Open WebUI • OpenRouter Chat • Perplexity • 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.
