The short answer

Choose Todoist if you need a mature, reliable place to capture and organise tasks, with deep integrations and team collaboration. Choose Do. if capture is already fine and the hard part is starting: deciding what matters today, splitting work that feels too big, and knowing how long anything will take.

Where they actually differ

Both apps parse natural language, sync across devices, work offline, and handle projects and due dates. Comparing those is a wash. The differences that change how your day goes are narrower than the feature lists suggest:

  • Todoist shows you everything due. Do. names one main focus and orders the rest around it, so the first decision of the day is already made.
  • In Todoist, breaking down "Redesign the website" is a step you ask its AI assistant to take. In Do. it happens by default — anything too big is split into startable steps without opting into an add-on.
  • Todoist has no built-in time estimate on a task. Do. estimates each one, which is the difference between a plausible day and a fantasy one.
  • Todoist Pro is a subscription. Do.'s free tier is the whole app, and its AI runs on your own provider key rather than a monthly fee to us.

Where Todoist is still ahead

Worth saying plainly, because you will find out in week two anyway. Todoist has a far larger integration ecosystem, more developed team and collaboration features, and over a decade of hardening behind its sync engine. Do. is newer. If shared projects or a specific third-party integration is load-bearing for your work, Todoist is the right call today.

Questions

What is the main difference between Do. and Todoist?

Todoist stores and organises tasks; Do. decides what to do with them. Todoist gives you projects, labels, filters, natural-language entry, and an optional AI assistant that can break a task down or suggest scheduling when you ask it to. Do. makes that judgement the default: it picks a main focus for the day, breaks tasks that are too large into startable steps, estimates how long each takes, and rebuilds the plan each morning without being asked. If your lists are already tidy but mornings still stall, that gap is the difference.

Can I import my Todoist tasks into Do.?

Yes. Do. imports Todoist tasks, including your projects, so switching does not mean retyping anything. The import runs inside the app and takes a couple of minutes. You can keep Todoist installed while you try Do. — nothing is deleted on the Todoist side.

Is Do. cheaper than Todoist Pro?

Do. is free to download with a free tier that stays free, where Todoist puts reminders, filters, and longer history behind a subscription. Its AI runs on your own OpenAI, Anthropic, or Gemini key, so you pay that provider directly — typically a very small monthly amount for task planning. Paid Do. tiers are planned but not yet available.

What does Todoist do better than Do.?

Todoist is more mature, and honestly so in several places: a much larger integration and plugin ecosystem, longer-established team and collaboration features, karma and productivity streaks if that motivates you, and more than a decade of stability behind its sync. If you need deep third-party integrations or shared team projects today, Todoist is the safer choice.

Does Do. work offline like Todoist?

Both work offline. Do. is offline-first: creating, editing, completing, and organising all run locally with no connection and sync when you reconnect. The one difference is that the AI features in Do. need a network, because they call an AI provider — everything else keeps working on a plane.
