Outl outlier: notes that don't corrupt when you sync them. (opens in new tab)

Open-source bullet-point outliner. Plain markdown on disk (no UUIDs), tree-CRDT sync that doesn't lose data when devices edit offline, and an MCP server so Claude, Cursor and ChatGPT use your notes as a second brain. A modern Roam, Logseq and Obsidian alternative built in Rust.
