Clipdown

Turn any webpage into clean Markdown in one click.

Clipdown is a fast, no-account, no-server browser extension for developers, researchers, and writers who work in Markdown-based tools — or who regularly paste web content into AI chat interfaces like ChatGPT, Claude, and Gemini.

── PASTE DIRECTLY INTO AI CHATS ─────────────────────

Markdown is the cleanest, most token-efficient format to feed into any LLM. Instead of dumping raw HTML or copy-pasting broken text, Clipdown gives you structured Markdown — with headers, code blocks, and tables intact — ready to paste as context for summaries, Q&A, or analysis.

Clip a docs page, research paper, or Stack Overflow thread and paste it straight into ChatGPT, Claude, Gemini, Cursor, or any AI chat interface. No noise, no clutter.

── HOW IT WORKS ──────────────────────────────────────

Click the toolbar icon, press Cmd+Shift+M (Mac) or Ctrl+Shift+M (Win/Linux), or right-click any page. Clipdown extracts clean Markdown and shows a live preview — rendered or raw — right in your popup. Then copy to clipboard or download as a named .md file.

── SMART EXTRACTION ──────────────────────────────────

• Page clip — auto-detects the main article content using Mozilla Readability, stripping ads, navbars, and clutter. Falls back to the full page DOM if no article is found.
• Selection clip — right-click highlighted text to clip only your selection as Markdown.

Clipdown also checks whether the site already publishes a Markdown version of the page (via alternate link hints, content negotiation, or .md sidecars) and prefers that over DOM extraction when available.

── FEATURES ─────────────────────────────────────────

✓ Three trigger points — toolbar popup, keyboard shortcut, right-click context menu
✓ Live preview — switch between rendered Markdown and raw text in the popup
✓ LLM token count — see the estimated token count (GPT-4 cl100k_base) for quick context budgeting

✓ YAML front matter — optionally prepend title, URL, date, description, and author
✓ Copy to clipboard or download as a .md file with the page title as filename
