How the work actually flows

It repeats. Daily full sync repeats process.

The problem it solves

You keep two task lists, one in Notion and one in Todoist, and every time you update one you have to remember to update the other. Tasks fall out of sync, and you end up double-checking both apps just to know what's actually true.

Who it fits

A solo operator or small team that manages tasks across both Notion and Todoist.

How it works

  1. A task is created, updated, or completed in either Notion or Todoist
  2. The system detects the change and checks the current state on both sides
  3. It updates the other app to match, keeping names, priority, due dates, and status in sync
  4. A daily full sync runs in the background to catch and fix any inconsistencies
  5. Your task list stays identical and up to date in both apps
What you get

Tasks staying identical across both apps

You get your Notion and Todoist tasks staying identical automatically, so a change in one always shows up in the other.

What you get

Two task lists, in Notion and Todoist, that always match each other without any manual updating.

What you need

A Notion account, a Todoist account, and a Redis instance to prevent duplicate updates.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
