What is CWC?
CWC is a tool built by an independent developer enabling engineers getting the best quality AI-assistance with a game-changing cost efficiency.
🧩 Compatible with VS Code, Cursor and Windsurf
✌️ 100% free and open source!
Guiding Principles:
- initialize popular chatbots—but don't game them
- everything you need—nothing you don’t
- respect privacy—zero tracking
- lightweight—under 1MB
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 open source software! 🫶
Context
Other tools try to "guess" what pieces of the codebase matter for the given task, often struggling to get it right. They workaround this by overloading context hurting model's performance and your wallet.
CWC works differently:
- You select which folders and files are relevant to the task
- You know exactly how many tokens you have in the context
The result? Unmatched in accuracy and cost AI assistance.
Too many tokens fighting for attention may decrease performance due to being too "distracting", diffusing attention too broadly and decreasing a signal to noise ratio in the features. ~Andrej Karpathy
Web chats
Use your favorite chatbot without tedious copy-pasting contents of files you want to include with your instructions.
Operates in two modes:
- General
Ask anything - Code Completions
Ask what fits the cursor position
Prompts with context and instructions can be copied to clipboard or sent directly to any supported chatbot.
Apply Chat Response is a smart tool that automatically integrates multi-file changes with the codebase by modyfing exisitng files or creating new ones. Works with chat responses in three edit formats: truncated, whole and diff.
Supported chatbots
(alphabetically)
- AI Studio
- ChatGPT
- Claude
- DeepSeek
- Doubao
- Gemini
- Grok
- HuggingChat

- Open WebUI

The Connector extension is available in Chrome Web Store and Firefox Add-ons.
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.
TIP: Practice single-turns
Chat conversations are only a construct of product interfaces, they hurt the quality of responses from the model and once your context is "poisoned" it will not recover. Whenever you're not satisfied with a reponse, the best practice is to alawys refine your initial instructions and re-initialize a chat.
