Claude Code Context Capturer

About

Claude Code Context Capturer turns any web page into clean Markdown and writes it directly to your project's CLAUDE.md — closing the "I researched something for an hour, now my AI agent has none of that context" loop.

Why use it?
• URLs alone don't always work — many LLMs can't fetch external content reliably
• Copy-pasting brings noise (ads, menus, footers)
• Manual paste-into-CLAUDE.md doesn't survive busy days
• Different projects need different context files

What it does:
• Direct write to CLAUDE.md — pick the file once with the File System Access API; subsequent captures append to it automatically
• Multi-project routing — link multiple CLAUDE.md files and route by URL glob (e.g. github.com/anthropic/* → one file, zenn.dev/* → another)
• Site-specific parsers for GitHub, Stack Overflow, Zenn, Qiita, MDN
• Generic parser (Mozilla Readability) for everything else
• Selection mode: capture just what you've highlighted
• Buffer mode: stack captures in extension storage for later export
• YAML frontmatter with URL, title, captured_at, tags
• One-click from toolbar / keyboard shortcut / right-click menu
• English and Japanese UI

Keyboard shortcuts:
• Ctrl+Shift+L (Cmd+Shift+L on macOS) — capture page
• Ctrl+Shift+K (Cmd+Shift+K on macOS) — capture selection

Privacy first:
• 100% local processing — nothing leaves your device
• No telemetry, no analytics, no external servers
• File handles stored locally in IndexedDB
• Open source under the MIT license
