Lichen
Shared knowledge, owned by you·lichen.wiki
Lichen lets you build shared wikis with friends on AT Protocol. Wikis are stored as ATProto records on your own PDS rather than locked into a single app, so notes stay portable across the network. Users can invite friends, assign roles, and edit collaboratively in real time, synced over the ATProto firehose. Notes are written in plain markdown with wikilinks, backlinks, and full revision history.
