Cosmo vs Todoist: which one should you choose in 2026?

Name: Cosmo
Availability: InStock
Author: Cosmo

Todoist is probably the most accomplished task manager on the market: 18 years of existence, native apps everywhere, formidable natural-language input. So why compare at all? Because the question is not "which is the best to-do list?" but "what does your system actually need?". If the answer includes habit tracking, time-blocking or measurable goals, the match gets interesting. An honest comparison, point by point.

The verdict in 30 seconds

Choose Todoist if you only want to manage tasks, with native apps (Windows, macOS, mobile), integrations across your whole ecosystem (Gmail, Slack, calendars) and extremely fast capture.
Choose Cosmo if you want to connect tasks, habits, a time-blocking calendar and OKRs in a single free tool, rather than juggling three or four applications.

Where Todoist is still ahead

Let us be direct: on pure task management, Todoist has an 18-year head start and it shows.

Natural-language input. Typing "Report every Monday 9am #Work" and watching the recurrence, the time and the project fill themselves in is the best on the market.
Native apps. System-wide keyboard shortcuts, a widget, capture from anywhere: if you capture 30 tasks a day, that comfort matters.
The ecosystem. Todoist plugs into Gmail, Outlook, Slack and your calendar. Cosmo, at this stage, offers no third-party integrations.
Collaborative maturity. Todoist's shared projects are battle-tested for running a whole team.

Where Cosmo changes the terms

Todoist's limit is not what it does, it is what it does not do. A complete personal system rests on four pillars, and Todoist covers one.

Habits are native. In Todoist a habit is a recurring task that makes you feel guilty when it is overdue. In Cosmo it is its own object: a 26-week GitHub-style heatmap, streaks, completion rate. Consistency gets built visually.
Time-blocking is real. You drag a task onto a calendar slot and the event is created and linked to the task. Planning your day takes two minutes, with no external sync.
OKRs give a direction. A to-do list tells you what to do today, it never tells you whether you are moving towards what matters. Cosmo's OKRs connect your daily actions to measurable goals (see our guide to the OKR method with 15 examples).
The price. Cosmo's main features are free with no project limit. Free Todoist caps at 5 projects, and the calendar view is paid.
Frictionless trial. The Cosmo demo opens with no account, pre-filled with 12 months of realistic data, so you can judge it loaded in two minutes.

Which tool for which profile?

You capture a great many tasks, everywhere, all the time

Todoist. Its lightning capture and native apps are built for exactly that.

You want to build habits as well as manage tasks

Cosmo. That is the structural difference: habits are a pillar here, not a workaround.

You plan your days with time-blocking

Cosmo, unless you already have a Todoist plus Google Calendar flow that suits you.

You set quarterly goals, personal or professional

Cosmo. Todoist simply does not have that building block.

Your whole team has to collaborate on projects

Todoist for heavy collaboration and integrations. Cosmo is enough for sharing tasks between two or three people, and goes further as soon as shared goals are involved, as the Cosmo for teams page shows.

Moving from Todoist to Cosmo

There is no automatic import today, but that is an opportunity to clear house: copy across only the tasks that are genuinely active (rarely more than 20), recreate your projects as coloured categories, then add what Todoist was not carrying: two or three habits and a first quarterly OKR. The user guide covers the full setup in ten minutes. If you work for yourself, the Cosmo for freelancers page shows the same flow applied to a client portfolio.

Conclusion

Todoist is an excellent tool, and if your need stops at tasks, keep it. But if your system looks like "a to-do list plus a habit app plus a calendar plus a goals spreadsheet", then the real question is not which to-do list is best: it is how to stop paying the friction between four tools. That is precisely Cosmo's bet, and you can check it in two minutes, free and with no credit card.
