Plugins & Extensions

Bring mdfy everywhere.

Capture from any AI, preview in Finder, publish from your editor. Every document gets a permanent URL — editable, versioned, and readable by humans and AIs across every platform.

What you can do

Research across AIs

ChatGPT researches → Extension captures → mdfy.app/abc123 → Paste URL in Claude → Claude refines

Move knowledge between AIs without copy-paste formatting nightmares. The document is the bridge.

Capture → Publish → Share in 3 seconds

See a great AI response → Click mdfy button → Beautiful URL auto-generated → Send to anyone

Recipient sees a polished document, not a raw chat screenshot. No app needed to view it.

AI-readable document references

Publish to mdfy.app/abc123 → Tell any AI "read mdfy.app/abc123" → AI fetches and understands

mdfy.app URLs work as context for any AI. Your documents become reusable knowledge across conversations.

Preview any .md file in Finder

Select file → Press Space → Full rendering with code, math, diagrams → Click "Open in mdfy.app" to edit

macOS QuickLook shows raw Markdown by default. mdfy QuickLook shows it beautifully rendered.

Publish from your editor

Write in VS Code → Cmd+Shift+M preview → One command to publish → Share URL with team

Never leave your editor. Write, preview, publish. The URL updates when you push changes.

Build reports from multiple AI sessions

Capture ChatGPT analysis → Capture Claude code review → Capture Gemini summary → Combine in mdfy.app → Single URL

Each AI has strengths. Combine outputs from multiple AIs into one professional document.

Short URLs that AIs can read

Every mdfy.app document has a short URL. Share it with humans or paste it into any AI conversation. Claude, ChatGPT, and Gemini can all fetch and understand the content — your documents become reusable context across AI sessions and platforms.

No login wall. No paywall. The URL works everywhere — browsers, AI chats, Slack, email, embeds.

Example

You: Read mdfy.app/abc123 and summarize the key points

AI: Based on the document at mdfy.app/abc123, here are the key points...

You: Now compare with mdfy.app/def456
