Code Web Chat is a chatbot-first AI coding tool. Start in VS Code (Cursor, Antigravity, VSCodium, etc.), then continue in ChatGPT, Gemini, Claude, etc. or Bring Your Own Key to stay in the editor!

CWC is free, works 100% on your machine and doesn't collect telemetry.

Tip

Elevate your workflow with smart workspaces (called projects, gems, or spaces).

Introduction

Coding capability in LLMs is trained using techniques like Inverse-Instruct with an existing model acting as a summarizer, looking at the code and writing instructions that could realistically output that exact code block.

By showing the model a complete set of files and task instructions in a single message, CWC taps directly into these snippet-summarization pairs.

Make simple instructions just work and the required reasoning effort lower or even disabled!

Tip

Get help in relevant file selection using the Find Relevant Files prompt type.

Prompt types

At its core, CWC constructs simple, markdown-formatted prompts for common use-cases (click to expand):

Edit files

Get accurate multi-file edits in a single response.

# Files
[full contents of selected files with paths]

# System
[edit format instructions (~250 tokens)]

---

[prompt]

Ask about files

Get help with whatever you're up to.

# Files
[full contents of selected files with paths]

---

[prompt]

Code at cursor

Get accurate inline snippets from SOTA reasoning models.

# Files
[full contents of selected files with paths]

### File: `[active file]`
```
[code before cursor]<missing_text>[prompt]</missing_text>[code after cursor]
```

[instructions for the missing text]

Find relevant files

Find files relevant to a query from a broad selection.

# Files
[broad file selection]

# System
[response format instructions]

---

Find a complete set of files relevant to the following query. Include the primary files as well as any structural files.
[prompt]

Important

The Apply response button placed under responses is not a means of automatic output extraction, it's an alias for the original copy to clipboard button. Review the content script to learn about implementation details.

Note

Use forwarding of port 55155 when using remote machine via SSH.

Built around prompt caching

CWC orders context files by modification and selection recency. This, combined with instructions placement at the message's very end utilizes prompt caching across single-turn prompts.

Make your chatbot quota last longer, lower input token costs by up to 90%, and reduce latency by up to 80%.
