Claude Code Context Capturer

Convert any web page into Claude Code-friendly Markdown context with one click.

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 Source code: https://github.com/OceansCreative/claude-code-context-capturer
