AI question-and-answer journal app that stores entries as markdown and syncs to Obsidian or WebDAV.

Mobile appfree

Lumma is an open-source journaling app for Android that combines a plain timeline mode with an AI chat mode for reflecting on the day. Connected language models can turn a conversation into a question-and-answer entry, write summaries and suggest tags. Entries are saved locally as markdown and sync via WebDAV or Obsidian, which suits people who keep their knowledge base in Obsidian but journal on a phone.
