More than a calendar
It doesn't just remember what to do when —
it helps you decide what to do today
A traditional calendar only minds the time slots. Action Calendar pulls your timed events, your pressure-free to-dos, and the ideas you haven't scheduled yet into one place — so you can see at a glance what today is really about.
Never miss a meeting or a to-do
Fixed-time meetings and appointments sit right alongside your no-deadline to-dos. The appointments you owe stay on your radar; the things you mean to do don't slip through.
Parking: park what you want to do, for later
The things you want to do but can't get to right now go into Parking. Today holds only what you'll actually move on — no more wall of tasks the moment you open the app.
Ideas and to-dos, living together
A task and its backstory stay in one place. Capture the details in rich-text notes — no more copy-pasting between two apps.

Make it yours
Let AI play the role you need
Through MCP, you plug in your own AI and write your own routines. Here's what some people are already doing — not limits, just starting points.Your way can look like anything.
AI as your PM
Sets your daily priorities, tracks progress, flags projects that have stalled for days, and tells you what to tackle first.
AI as your collaborator
Break down tasks together, organize the context in your notes, and turn a fuzzy idea into a few actionable next steps.
AI as your life coach
Morning check-ins, evening retros, and a nudge to slow down and take care of yourself when you're pushing too hard.
AI as your …
Write your own routine. We don't assume how you "should" use Action — that's up to you.
How it works
Three steps to bring in your own method
Connect your agent
Add Action's MCP connector in Claude or Codex, authorize with OAuth, and you're done in seconds. No API key needed.
Pick a routine, or write your own
Start from a template, or build a way of working that's entirely yours from scratch. The prompts and the rhythm are all yours.
Let it run
Your AI works the way you defined, reading and writing your tasks and notes. You check, tick, and swipe right on your phone.
BYOA — your AI, your call
Pick Claude, Codex, or any MCP-capable agent. You write the prompts and routines. No lock-in, no black box, no built-in AI you can't out-think.
The longer you use it, the better it knows you
Estimate calibration, habit stats, time-of-day patterns, stalled detection — your data compounds into a backend that gets you. That's something a single file could never compute.

FAQ
Is Action Calendar a calendar or an AI tool?
It's a new kind of calendar — it manages your events and your to-dos, and you can use it on its own. What sets it apart is open MCP: plug in your own AI and it becomes whatever working system you need.
What can I use it for?
You decide. As your PM, your collaborator, your life coach, your writing assistant, your habit coach… We offer templates as a starting point, but we don't limit how you use it.
Does it cost anything?
It's free. The AI runs on your own subscription (your Claude / Codex), so we can afford to keep it free for good.
Which agents are supported?
Any MCP-capable one — Claude (claude.ai connector or Claude Code), Codex, and more. The one you already use just plugs right in.
Do I need to code?
No. The connector installs in one click and routines start from templates. If you can write a prompt, you can tailor it even closer to you.
