Flume
The GTD app that runs itself.
Capture anywhere. Flume plans your day, clears your inbox, and runs your weekly review. You just approve.
Finally, a task manager that runs itself.
OmniFocus is powerful, but it's all on you. The new AI apps talk a good game, with no real engine underneath. Things is calm, but it won't move your work forward. Flume brings it together. A rigorous engine. A capable copilot. Every way to capture. So the app can run the method for you. You just approve.
OmniFocus
Powerful. All on you.
AI to-do apps
Talk. No engine.
Things
Calm. No power.
Flume is all three. The engine, the copilot, and every way to capture.
The name
A channel for everything on your mind.
A flume is a channel built to carry water. Swift, steady, always moving toward where it's meant to go. Flume does the same for your work. Thoughts flow in, find their place, and keep moving. Nothing pools. Nothing stalls.
What makes Flume different.
The Ritual Engine
Three guided flows that do the practice of GTD for you. Not summaries. Decisions, one tap each. And it all works even without an AI key.
- ▸Morning Brief. A plan for your day, as simple accept, defer, or skip cards.
- ▸Evening Shutdown. See what slipped. Set up tomorrow.
- ▸Weekly Review. Flume reads every project first and flags what's stalled or missing.
Pilot
A copilot built into the app. It reads from the engine, and it never changes a thing without your tap. Want the wheel? Bring your own AI key.
- ▸Capture in plain language. Split a big brain dump into real tasks.
- ▸Triage your inbox, catch duplicates, learn your estimates.
- ▸Plan your day as cards you approve. Never a silent change.
Email, made for doing
A full email client built for getting things done. Turn a full inbox into next actions with the keyboard. Then keep an eye on what you're waiting for.
- ▸IMAP, Gmail, and Outlook. Compose, reply, send, drafts, signatures.
- ▸Keyboard triage on Mac. Inbox to action in one pass.
- ▸A Waiting for Reply view that tracks your open loops.
Make it yours.
Eight app icons across the spectrum. Pick the one that fits your home screen. Change it whenever the mood does.
