Convert Mastodon Posts to Markdown

Mastodon is the flagship of the decentralized fediverse, running on the ActivityPub protocol with thousands of independent instances. Converting Mastodon content to Markdown extends its portability even further.

AnyPost works with any Mastodon instance — not just the big ones — converting posts, threads, and replies to clean, portable Markdown.

Why Convert Mastodon to Markdown?

Fediverse Portability

Mastodon is already decentralized, but Markdown adds:

• Offline access — read without federation
• Long-term archiving — immune to instance shutdowns
• Searchable content — full-text search in your notes
• AI-ready format — feed to LLMs without federation complexity

Instance Diversity

With thousands of Mastodon instances:

• Community-specific content — niche interests, languages, topics
• Cross-instance discussions — threads spanning multiple servers
• Self-hosted content — personal instances, single-user servers
• Ephemeral communities — temporary or themed instances

AnyPost handles them all transparently.

How It Works

Any Instance, Same Pattern

# mastodon.social
Before: https://mastodon.social/@username/112233445566778899
After:  https://anypost.md/mastodon/@username/112233445566778899

# mstdn.social
Before: https://mstdn.social/@username/112233445566778899
After:  https://anypost.md/mastodon/@username/112233445566778899

# Your own instance
Before: https://myinstance.net/@username/112233445566778899
After:  https://anypost.md/mastodon/@username/112233445566778899

The domain changes, but the pattern stays the same.
