**Plain files.** Every note is a markdown file on your filesystem. No proprietary database, no lock-in. You can open, edit, and search your notes with any text editor.
**Structure without rigidity.** Notes have types, properties, and relationships — but they're just YAML frontmatter. The structure lives in the file, not in a schema.
Laputa is designed to grow with you. Start with a few notes, add types as patterns emerge, connect ideas with wikilinks. Over time, your vault becomes a map of how you think.
