Decant - Web to Markdown Clipper 作者: Covai Labs

Decant 🍷 — Web to Markdown Clipper

Decant is a fast, privacy-first, open-source browser extension that turns any webpage or article into clean, structured Markdown — right in your browser.

Clip once. Paste anywhere: Obsidian, Logseq, Bear, Notion, ChatGPT, Claude, or anywhere else you write.

WHAT IT DOES

Click the Decant icon on any article, blog post, documentation page, or news story. Decant instantly extracts the main content — stripping ads, sidebars, and navigation — and converts it into clean Markdown.

From the popup you can:

• Copy the Markdown to your clipboard
• Download it as a .md file
• Open it directly in Obsidian, Logseq, Bear, NotePlan, or Drafts
• Send it to ChatGPT, Claude, Gemini, DeepSeek, or Perplexity for AI analysis

FEATURES

📄 Clean Markdown Extraction
Powered by Mozilla's Readability — the same engine that powers Firefox Reader View. Extracts article body, headings, lists, code blocks, and links. Cuts everything else.

🔒 100% Local & Private
All processing happens in your browser. No servers, no accounts, no tracking, no telemetry. Your reading habits are entirely your own.

📋 YAML Frontmatter
Optionally prepend structured YAML metadata to every clip — title, source URL, author, publish date, clip date, and tags. Fully customizable template.

📝 PKM & Note-Taking App Integration
One-click open in your preferred app via URI scheme:

• Obsidian (obsidian://) with optional vault selection

🤖 AI Chat Handoff
Copies a formatted prompt to your clipboard and opens your preferred AI platform in a new tab — ready to paste and analyze the article.

NOTES FOR FIREFOX STORE REVIEWERS

• host_permissions (<all_urls>) is required because the extension must inject a content script to extract article content from any user-initiated page. It does not make any network requests of its own.
• innerHTML usage in content/content.js is from the bundled @mozilla/readability library (mozilla/readability on GitHub), which uses DOM manipulation internally for article parsing.
• Source code is available in the submitted source zip and at https://decant.covai.org/
