AI Task Managers: Todoist vs TickTick vs Sunsama (2026)

I missed a dentist appointment in March. Not because I forgot it existed. Because it lived on a sticky note. On a monitor I hadn’t looked at in three days. Yeah.

That was the day I gave up on my memory (unreliable) and my sticky notes (invisible) and started actually testing task managers. Like, living in them. Not a 20-minute demo. Weeks.

AI task managers, the real pitch, is this: they don’t just store your tasks. They help you decide what to do first, when to do it, and how long it’ll actually take. Keyword: actually. I spent the last few weeks inside the three big names (Todoist, TickTick, Sunsama) to figure out which one deserves a spot on your phone.

TL;DR: Todoist is the best all-rounder: fast, reliable, cheap, and the one I’d hand to a friend. TickTick gives you the most stuff per dollar: calendar, habits, Pomodoro, all built in. Sunsama costs real money, but it’s the only one that plans your whole day for you, hour by hour. Just want a list? Todoist. Want your day planned? Sunsama.

What is an AI task manager?

What is an AI task manager? An AI task manager is a to-do app that uses artificial intelligence to prioritize your tasks, estimate how long they’ll take, pick the best time to do them, and reshuffle everything when your day blows up. A plain checklist records your schedule. This thing makes decisions about it.

Honestly, the “AI” label gets slapped on a lot. Some of these apps autocomplete a date and call it AI. (It’s not.) Others look at your calendar, your deadlines, how you actually work, and build you a plan. These three sit at very different points on that spectrum. That’s why comparing them is interesting.

Here’s why the decision part matters more than the storage part. Asana’s Anatomy of Work Index found that knowledge workers burn 58% of their time on “work about work”: hunting for information, chasing updates, sitting in status meetings, instead of doing the actual work. A task manager that only stores your list? Does nothing about that 58%. One that plans your day? That can actually shrink it.

Why do to-do lists keep failing?

Because they’re storage, not planning. You dump 23 tasks onto a list, stare at the wall of text, and pick the easiest one instead of the most important. Nobody tells you what fits in today, what can wait, or what takes ten minutes versus two hours. AI task managers fix the deciding, not just the storing.

My old system: a notebook, fresh page every Monday. By Wednesday the page was chaos: crossed-out items, arrows everywhere, stuff I’d rewritten three times. By Friday I’d stopped looking at it entirely. Sound familiar? The list wasn’t broken. I was. No plan for which items belonged to which day, no honest sense of how long anything took. Classic.

Todoist: the one that just works

Todoist has been around since 2007, which in app years is basically ancient. And it shows, in a good way. Todoist says more than 30 million people use it. After a few weeks, I believe them.

Quick add is the whole game. You type “Call mom every Tuesday at 6pm” and boom: recurring task, right day, right time. No dropdowns. No date-picker hell. Sounds small, right? It’s the difference between capturing a task in four seconds and losing it forever. Four seconds.

What I like:

• Fastest task capture of the three, and it’s not close. Feels like texting yourself.
• Filters and labels that let you build views like “errands near home” or “work stuff under 15 minutes.” Nerdy. Useful.
• It’s everywhere: phone, desktop, browser, even a smartwatch.

What I don’t like:

• Free plan caps you at 5 projects. That dies fast once you split work, home, and a side project.
• The newer AI stuff, suggested subtasks and the like, feels thin next to Sunsama’s full-day planning.
• No real calendar view unless you pay. Annoying.

Pricing: free for the basics, Pro around $5/month billed annually, Business around $8 per user per month. Check Todoist pricing for the current numbers.

Never used a task manager before? Start here. This is the one I recommend to actual friends, because it’s the one they’re still using two weeks later. That matters more than any feature list.

TickTick: the most bang for your buck

Imagine Todoist, then someone bolts on a calendar, a habit tracker, a Pomodoro timer, and an Eisenhower Matrix, and charges you less. That’s TickTick. Premium is $35.99 a year. Do the math: about $3 a month. For that money it replaces two or three separate apps.

The habit tracker is what kept pulling me back. “Read 20 pages.” “No sugar.” Right there next to your tasks, with streaks and stats. If your goals currently live in five different apps, TickTick is a consolidation play.

What I like:

• Calendar, habits, Pomodoro, tasks: one app, less than a coffee a month.
• The Eisenhower Matrix view sorts everything into urgent/important quadrants. Genuinely great on overloaded Mondays.
• Smart lists and filters nearly as good as Todoist’s.

What I don’t like:

• Busy interface. Lots going on. Budget a week to learn it.
• AI features are lighter here: smart date parsing, some suggestions. Not real planning.
• Desktop app feels like an afterthought next to the mobile one.

Cheapest way to get the most? This is it. Also worth a look if you’re already paying for a separate habit tracker: cancel that subscription. And if email is where your tasks go to hide, read how I cut my email time in half with AI first. No task manager survives an inbox that refills itself.

Sunsama: the daily planner, not just a list

Different animal entirely. Sunsama doesn’t just hold your tasks. Every morning it walks you through a ritual: pull in today’s tasks, drag them onto your calendar hour by hour, and decide what honestly fits. End of day? Another ritual: what got done, what moves to tomorrow, what you need to stop pretending you’ll do.

That ritual is the product. And, I’ll be honest, it works. Sunsama days: I knew exactly where my time went. Non-Sunsama days: I wondered where it went. But. No free plan, just a 14-day trial. And about $20/month billed monthly (about $16 annual), which is more than Todoist and TickTick combined. It stings.

What I like:

• The morning ritual forces an honest plan. You cannot cram 14 hours of work into an 8-hour day and pretend otherwise. The app won’t let you lie to yourself.
• Pulls tasks from Gmail, Slack, Asana, Trello, Todoist. One plan, one place.
• The shutdown ritual is the best anti-guilt feature I’ve used. Unfinished work gets rescheduled on purpose, not forgotten.

What I don’t like:

• The price. You have to justify this one. It’s not a no-brainer.
• Overkill for a simple day. If your life is three tasks and a meeting, this is a lot of ceremony.
• No free tier. The trial is your only taste.

Pricing: about $20/month billed monthly, around $16/month annual. Check Sunsama pricing for the latest.

Sunsama pairs nicely with an AI calendar assistant when meetings eat your day. And if you freelance and juggle several clients at once, the daily ritual is worth trying. For pure capture speed, though? Todoist still wins.

So which one should you actually pick?

Todoist if you want a fast, reliable list you’ll actually open. TickTick if you want the calendar, habits, and Pomodoro without four subscriptions. Sunsama if your problem isn’t forgetting tasks. It’s never having a realistic plan for the day. Forget the feature tables. The right one is the one you open every morning.

One more honest thing. I’ve tried the “free forever” route for this. Most of those tools either cap you hard or monetize your attention. If you want to spend zero dollars, start with Todoist’s free plan, or skim the free AI tools that actually compete, before paying for anything.

A setup that actually sticks

Here’s the uncomfortable truth: the app matters less than the setup. This is the one that worked for me.

First: one inbox. One app, one inbox, zero exceptions. The second your tasks live in three places, you trust none of them. I learned this the hard way. Twice.

Second: plan tomorrow tonight. Five minutes before you shut the laptop: look at tomorrow’s calendar, drag three to five tasks onto it. Done. You’ll sleep better, and you’ll wake up knowing what comes first. I fold this into how I plan my whole week with ChatGPT: twenty minutes on Sunday, and the daily “what now?” spiral disappears.

Third: seven items max. That’s the honest ceiling for a day with meetings, email, and an actual life. Twelve items isn’t a plan, it’s wishful thinking. Move the rest to tomorrow. Feel the relief. I’m serious. Try it once.

Conclusion

Three weeks, three apps. I kept Todoist on my phone and Sunsama on my work laptop. Todoist for catching everything at speed. Sunsama for the mornings when I need someone (something) to tell me what today actually looks like. TickTick lost for me personally, but on a budget? Obvious pick. Anyway: the app is maybe 20% of it. The other 80% is five minutes tonight, planning tomorrow. Do that part and almost any of these will work.
