Guiding principles:
- initialize popular chatbots—don't scrape responses
- API tools—battle-tested must-haves
- 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 love free and open source software 🫶
See how simple it is to implement a feature with ChatGPT:
Workflow with CWC is simple and effective:
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 understanding of the codebase they work on. Verifying AI-suggested changes can become challenging, making it easier for bugs or unintended behaviors to slip in.
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.
The benefits of this friction include:
- developing a mental model of the codebase
- eliminating idle time while waiting for the AI to figure things out,
- improved speed, quality, and cost efficiency of AI assistance.
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.

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.
