What is Lichen?

Sign in with your Bluesky account, create wikis, and write in plain markdown with [[wikilinks]]. Your data lives on your own PDS: it persists independently of this app, and your Bluesky identity works everywhere on ATProto.

Contributors write directly to their own Personal Data Server via OAuth. The Lichen appview ingests those records from the network firehose, assembles wiki state, and serves reads. Your data is never locked in: it follows you across the ATProto ecosystem.

Public wikis are readable by anyone, with no account required. The notes in them are stored on the creator's PDS and served publicly. Private wikis are only accessible to approved members. The notes are still on your PDS, but Lichen enforces access controls so only members can read them. Fully private wikis will be developped once the protocol permits private data.

Features:

  • Wikilinks and backlinks: link notes with [[double brackets]], backlinks are tracked automatically
  • Revision history: every edit is a diff, full history is always available
  • Access control: public or private wikis, with admin/contributor/viewer roles
  • Real-time sync via the ATProto firehose
  • Data portability: your wikis and notes are ATProto records on your PDS, not locked in
  • Markdown editor with split-pane live preview, image upload via drag-drop/paste
  • Multilingual UI (English and French)
  • Self-hostable: deploy your own instance, fully independent
