Browser extension (Chrome & Firefox). Clip precise web context into AI-ready Markdown.

Not just another web-to-Markdown converter.
ContextClip is a precision tool for feeding local LLMs.

Text-only LLMs need clean context, not whole pages.
You want three paragraphs from a GitHub README, one section from a paper, one clean chat transcript, or a selected block from a private page, without nav, ads, comments, or layout junk.

Everything runs entirely in your browser.
No server. No API key. No page data leaving your machine.
Works on login-required pages that server-side fetchers can't reach.

## What It Does

### Copy This Page

One click. Pull the main content, clean the noise, attach source metadata, copy Markdown.
![copy this page](https://raw.githubusercontent.com/WingEdge777/ContextClip/main/resources/2.png)

### Pick & Extract

![select](https://raw.githubusercontent.com/WingEdge777/ContextClip/main/resources/1.png)
Need only one section, code block, or table:

- **Hover + click** — pick one semantic block
- **Drag a rectangle** — capture an exact visual area

Picked content also goes through site-specific cleanup when available.

### Output

- Text-first pages → `.md`
- Media-heavy pages → `.zip` with `page.md` + `manifest.json` + `assets/`

Every result includes YAML frontmatter: title, source URL, site, author, captured time, and extraction mode.

Chat pages are exported as structured turns:

```markdown
# Conversation Title

## user

Question here...

## chatgpt

Answer here...
```

## Site Support

General extraction works on any page via Readability. Deeper cleanup for:

- **arXiv** — full paper via HTML endpoint, metadata via API, abs-page fallback, page + picked fragments
- **Chat web** — ChatGPT, Gemini, DeepSeek conversation transcript export, code fence cleanup, user/assistant turn structure(now we can easily save ours conversations)
- **GitHub** — README, rendered docs, single file views, page + picked fragments
- **微信公众号** — article body, author, title, page + picked fragments
- **知乎** — column posts, answers, page + picked fragments

Quality over coverage. Better to trust a few adapters than ship thirty weak ones.

source_url: 'https://example.com/page'
site: 'example'

captured_at: '2026-04-28T10:45:13.901Z'
mode: 'selection'

---

Page content here...
```

### ZIP fallback

For media-heavy pages:

```text
page-export/
  page.md
  manifest.json
  assets/
```

## Why It Exists

LLMs are good at reasoning over clean text.

Web pages are not clean text.

ContextClip sits between them.

## Development

```bash
bun install
bun run dev          # Chrome / Edge (watch mode)
bun run dev:firefox  # Firefox (watch mode)
```

```bash
bun run test:golden
bun run test:golden:update
bun run bundle:ext          # Chrome package
bun run bundle:ext:firefox  # Firefox package
```

Watches source and rebuilds `dist/`. After each rebuild:

1. Open `chrome://extensions` (Chrome) or `about:debugging` (Firefox)
2. Find **ContextClip**
3. Click reload
4. Refresh target page if content script changed
