Memos vs Obsidian

Both keep your notes in Markdown, but they solve different problems. Memos is a self-hosted web app for fast, chronological capture you reach from any device. Obsidian is a local-first desktop and mobile app for building a densely linked knowledge base.

Choose Memos if you want quick, private capture on your own server. Choose Obsidian if you want an offline, deeply linked knowledge graph on a single machine.
