Diarize puts your to-do list in the gaps you actually have.
Diarize is an automatic calendar scheduler. It reads the tasks you already keep in Todoist, Microsoft To Do, Linear, Notion or TickTick and books each one into free time on your Google or Outlook calendar — around your real meetings, in priority order, and it tells you exactly why every block is where it is.

Brings work in from
Writes it to
It works around the week you actually have.
Meetings, all-day events, invitations you declined, other people's holds — all of it counts. Tasks land in the gaps that are genuinely free, ordered by what matters and what is due first. Nothing gets booked over your life.
What it read before deciding
It tells you why. Actually why.
Every block carries the real reason it landed there — which task outranked it, which meeting pushed it, which gaps were too short to fit. Not a summary written after the fact: the scheduler is deterministic, so what you read is the decision it made, not a model's guess at what it might have done.
Why "Board deck" is on Monday at 9
The parts most auto-schedulers get wrong
It doesn't argue with you
Drag a block and it stays where you put it. Delete one and the task is marked done in your task app. Your calendar is the control surface, not just somewhere output lands.
It only ever touches its own work
Every block Diarize creates carries a marker. It will only move or remove events carrying that marker — your meetings are read as busy time and are never edited, moved or deleted.
Nothing new to check
No new inbox, no new app, no migration. Keep the task list you have and the calendar you already live in. Diarize has no interface you need to visit daily — that's the point.
What Diarize asks for, and why
Diarize only requests the access it needs to build your schedule, and it is easier to trust a tool that says so on the way in rather than in the small print.
To read your calendar
So it knows when you are already busy. Diarize reads the start and end times of your existing events to find the gaps that are genuinely free. It does not use the contents of your meetings, and it never shows them to anyone.
To write to your calendar
So it can place your work in those gaps, and move or remove those blocks as your task list changes. Every block it creates carries a marker, and it will only ever edit or delete events carrying that marker — your own meetings are never touched.
To read your task list
So it knows what there is to schedule. Diarize reads open tasks — title, priority, due date and estimated duration — from whichever app you connect, including Google Tasks. Nothing is sold, shared or used to train models.
To tick tasks off
Delete a block from your calendar and Diarize marks that task complete in the app it came from, which is why it needs write access to your tasks as well as read. It never creates or edits tasks you did not write.
The full detail is in our privacy policy, and you can disconnect or delete everything at any time.
Simple pricing
Motion is $34 a month. Diarize is one small server and a database — so we would rather charge a fifth of that than spend it making the scheduler mysterious.
