The fastest inbox for
your brain —notes, todos, and
reminders in one.
One app that turns fleeting ideas into notes, tasks into progress, and reminders into peace of mind.
Built different.
Designed for thinkers.
Privacy by design
Your notes stay yours. End-to-end encryption at rest and in transit. No ads.
Codex gives you the balance.
Powerful enough to replace the giants, simple enough to avoid clutter.
Inspired by Zettelkasten
Codex strips away the noise of complex apps, leaving only speed and clarity.
