OpenTime

OpenTime is a new plain-text standard designed to bring clarity and ownership to the way you manage your time.

Where Markdown made your thoughts portable, OpenTime makes your schedule portable — across apps, devices, platforms, and decades.

Most productivity tools lock your data inside their system. Your tasks live in one app, your habits in another, your schedule somewhere else — and none of them speak a shared language.

Even when they claim to “sync,” you're still stuck inside someone else's worldview.

OpenTime changes that by giving you:

• A single format for everything: goals, tasks, habits, reminders, events, appointments, and projects
• Plain-text files you own locally (.ot)
• Total portability between apps who are open enough to adopt a standard, or accept a standard at all
• No vendor lock-in
• Future-proof, human-readable data

Your time should belong to you — not to the tools you use.

Time is the most valuable thing you have. In some philosophies, it's the only thing you have.

It deserves a format that's:

• portable
• future-proof
• open
• flexible
• and truly yours

OpenTime gives you the freedom to structure your life the way you want — and take it with you wherever you go.
