A planner that remembers YOU.
You cannot connect the dots looking forward, only backwards.— Steve Jobs
Free forever · Bring your own agent · Your data stays yours
Product surface
The planner remembers you, not just the next checkbox.
Group your life into workspaces.
Separate the ventures, projects, people, and brain dumps without losing the rollup.
Workspaces →
A real API for your real agents.
Agent-addressable tasks, seasons, brain dumps, webhooks, presence, and journal.
API →
Work with you, not on you.
Plan your day, surface what is slipping, draft the journal, and stay attributed.
Agents →
Build with your people.
Share workspaces with the people who help you keep momentum. They see the workspace you invite them into, not the private mess around it.
The work moves together.
Sound familiar?
You had the idea at 11pm.
You woke up and it was gone.
You started ten things this week.
You can't remember why you started any of them.
The to-do app shamed you on Sunday.
You deleted it on Tuesday.
Here's the shape of it.
Brain Dump
Catch the idea before it's gone. No structure required.
Today
Three priorities. Real time. Nothing else.
Projects
When an idea is ready, it grows up. You decide when.
More than a to-do list
The planner plans, remembers, and looks back with you.
Motion
The day arrives already planned. A morning pass packs your grid and stages your top 3 into the empty slots — your pins stay sacred. Miss a block and it slides to the next free gap instead of shaming you.
Journal + Books
Close the day in the journal, group entries into books, and share any entry or book with a revocable link. Scan a two-page spread and it splits and transcribes both halves for you.
Seasons
Quarters, months, and weeks stack behind your day, so today's three priorities ladder up to something. Look back to see the dots connect.
One brain. Many lives.
Work. Side hustle. Family. Each part of your life gets its own workspace — its own projects, members, and rhythm. Switch between them with one click; nothing leaks across.
You're not one role. Your planner shouldn't pretend you are.
Bring the people who matter into the work that matters.
Add friends. Share a task. Share a whole project. Assign work across workspaces without losing the boundaries between them. The people in your corner deserve to see what you're building — and help carry the weight.
Built for the team that doesn't share an office.
Why we made this
We built this because we needed it.
Our brains catch fire on ten ideas at once. Notebooks fill up. To-do apps shame us. We kept losing the one idea that mattered to the noise of the other nine.
Timebox is the planner we wished existed — one that catches the spark, holds your momentum, and lets ideas grow up when YOU decide they're ready. Not when an app's algorithm says so.
Your AI teammate
Bring your agent. Timebox is built for both of you.
Most planners are built for humans only. Timebox is built for humans AND their agents. Per-key identity, scoped permissions, action attribution, live presence — every action your agent takes shows up next to your name. Plug in Claude Code, ChatGPT, your own scripts. We give you the surface; you bring the brain.
Built for the human-and-agent team.
Screen Time companion
Your Mac won't let you drift.
The TimeBox Gatekeeper is a menu-bar app that takes over your screen until your day is set up — top 3 chosen, brain dumps sorted. It releases when you're ready, and drops a bedtime curtain at night.
Works with Claude Code
Four commands. Your agent runs the loop.
A public skill pack for Claude Code. Install once, and Claude Code picks up your priorities, drops in captured thoughts, and closes what you shipped — through the same scoped API your other agents use.
