What is CWC?

CWC is a non-agentic coding tool for AI-assisted programming built by an independent developer.

🧩 Compatible with VS Code, Cursor and Windsurf
✌️ 100% free and open source!

Guiding Principles:

• initialize popular chatbots—but don't game them
• API features—powerful yet simple to use
• respect privacy—zero tracking
• lightweight—under 2MB

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
• Mistral
• Open WebUI
• OpenRouter Chat
• Qwen
• Yuanbao

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.

Code completions

The tool is designed to provide you with the highest quality autocomplete suggestions at the cost of latency. Intented to be used on-demand through the Tools tab, via the command palette or a keybinding. Setup multiple configurations and choose between them based on difficulty of the completion.

✓ Includes selected context
✓ Works great with any model

Refactoring

Modify files based on natural language instructions.

✓ Includes selected context
✓ Like chat in diff edit format

Commit messages

Generate meaningful commit messages. The tool first attaches affected files, then the customizable instructions, then diff of changes. Not lobotomized context ensures unmatched accuracy.

✓ Includes affected files in full
✓ Customizable instructions
