Faster than your memory.
Cold start in under 40 milliseconds on a five-year-old laptop. Because if it's slow, you won't write in it.
Kairos is a small, keyboard-first note-taker. It doesn't sync to twelve platforms, doesn't sell you a database, and doesn't ask what your weekly goals are. It just opens, quickly.
Cold start in under 40 milliseconds on a five-year-old laptop. Because if it's slow, you won't write in it.
Every note is a .md file on disk. No proprietary database, no lock-in, no panic if we close the company next year.
Every action lives behind cmd+k. If you can name it, you can do it. If you can't name it, it probably shouldn't exist.
We do not autocomplete your sentences. We do not summarise. The cursor is yours. Your thoughts are yours.
Dim everything except the line you are writing. Ten-year-old idea, still good. Toggle with one keystroke.
Clean HTML, archival PDF, or a single-page website if you need one. No "export as JSON" — we don't think you'd use it.
"It feels like a notebook that happens to know shortcuts.
Not a database pretending to be a notebook." — Ariel M., essayist · two-year subscriber
No monthly fee. No seats. No sync service to lock into. Install on every computer you own. Keep every version we ship this year. Simple.
