The problem it solves

Keeping the same task list up to date in two different apps means updating each one by hand, and it's easy to forget which version is current. Tasks fall out of sync, get duplicated, or quietly disappear.

Who it fits

Anyone who manages tasks in both Notion and Todoist and wants one source of truth.

How it works

  1. A task is created, updated, or completed in either Notion or Todoist
  2. The system checks both sides to see what actually changed
  3. It updates the matching task on the other side, including name, priority, and due date
  4. A daily check runs in the background to fix any tasks that fell out of sync
What you get

Tasks that always match across apps

You can keep your Notion and Todoist tasks matching automatically, so a change in one updates the other right away.

What you get

Matching, up-to-date tasks in both Notion and Todoist without manual copying.

What you need

Accounts with Notion, Todoist, and a Redis database for tracking sync state.

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.
