Lumina captures what you write and surfaces what you've forgotten. Your second brain — fast to reach, hard to overwhelm.

Most note apps are databases. Lumina is a thinking partner — it holds context, resurfaces relevant material, and helps you make sense of what you know.
Ask Lumina anything about your notes in plain language. It understands context, not just keywords — finding the idea you half-remember but can't name.
Lumina detects when a new note echoes something you've written before and links them automatically — without you having to manage a tag taxonomy.
Spaced resurfacing brings notes back when they're most useful — before a meeting where the topic will come up, or when you start something related.
Markdown that gets out of the way. A distraction-free canvas with keyboard-first navigation, slash commands, and the speed of a local app.
No seat multipliers. No storage surprises. Pay for what you use and grow when you're ready.
