Quick answer: Goblin Tools' Magic ToDo is the most direct AI task breakdown tool here. It's free on the web, splits a task into smaller steps, and lets you ask for finer steps with a "spiciness" setting. Tiimo's AI Co-Planner breaks tasks down inside a visual planner, and Todoist's Task Assist does it for Pro subscribers. Motion's AI drafts whole work projects. Routinery has no in-app AI breakdown we could confirm, but Claude or ChatGPT can build a routine and save it into the app.
A task like "clean the kitchen" can sit on a list for a week untouched, even though you know what the finished room looks like and can't see where to begin. Each app below takes a task that size and writes out smaller steps for it.
Every app here uses AI for the splitting. If your trouble is starting, switching between tasks or losing track of time, our roundup of apps for executive dysfunction across starting, switching, memory and time compares six apps on all four. We make Routinery. It is listed alphabetically in the tables below, and its limits get their own section.
Research on breaking tasks into steps: what the studies show
Writing out subtasks raised people's own rating of how likely they were to finish a task they'd been putting off, in one large trial, but we found no study that tested an AI app doing the splitting for adults with executive dysfunction.
In a 2025 trial with 1,035 participants, Garg, Shelat and Schooler randomly assigned people to one of three groups. The experimental group named their feelings about a task they had been avoiding, then broke it into subtasks and picked a reward. They rated themselves more likely to complete it than either control group did, and reported better mood. The outcome was a self-rating after a single session, with no follow-up on whether the tasks were finished.
A 2026 meta-analysis of 39 trials by Gibson and colleagues looked at graded tasks, where a goal gets raised in small increments. It found a medium effect on physical activity (g = 0.61), and the number of increments explained a significant part of the variation between studies. Graded tasks always came packaged with goal setting and action planning, so the effect cannot be pinned on the steps alone. The authors rated the certainty of evidence low.
In a 2025 study, 27 neuropsychologists and rehabilitation specialists rated executive function rehabilitation plans that ChatGPT wrote for three hypothetical people with ADHD. Dahò and Caci found the experts scored feasibility below the plans' theoretical grounding, pointing to thin personalization and techniques nobody had validated. The plans also assumed resources people might not have. They were clinical rehab programs. Goblin Tools is cautious about its own output too, calling every answer from its tools "only guesswork" on its About page.
Five AI task breakdown apps compared: price, platforms and what the AI does
Prices, plans and features come from each app's official site, help pages or store listings as of 2026-11-06. Apps are in alphabetical order.

In the table below, "couldn't confirm" means we found nothing in the official site, help pages or store listings. The feature may still exist.
| App | Where the steps end up | Timer while you do them | Review before anything is saved |
|---|---|---|---|
| Goblin Tools | A checklist in the website or app, exportable to Todoist, TickTick, Notion, Asana or Amazing Marvin | Estimator gives a rough time guess. Couldn't confirm a running timer | Steps land in your list, where you edit or remove them |
| Motion | Tasks and projects that its auto-scheduler places on your calendar | Couldn't confirm a per-step timer | Yes. Drafts appear in AI Chat first |
| Routinery | A routine, run one step at a time | Each step runs on its own timer while a voice calls out the next | Yes. You approve each routine before it's created or changed |
| Tiimo | Your visual schedule and to-do list | The focus timer starts on its own when a scheduled task begins | Couldn't confirm |
| Todoist | Sub-tasks under the original task | Couldn't confirm a built-in timer | Couldn't confirm |
Goblin Tools: Magic ToDo for the one task you're stuck on
Goblin Tools' Magic ToDo works like a plain to-do list with a button that writes out the steps for any item you give it. Its App Store listing names executive dysfunction among the conditions the tools are meant to support.
A spiciness setting controls how fine the cut is. You tell it how hard or stressful the task feels, and a spicier setting makes it try for more, smaller steps. Goblin Tools calls this a hint to the system. The step count is not fixed. You can change the level for the whole list whenever you like. Each item can take its own subtasks, and Estimator will guess how long one might take.
Pro adds sync between devices, reusable templates and sharing. We found no reminders on the About page or in either store listing. The breakdown itself stays free on the website, and the About page says most tools run on general purpose AI models whose accuracy varies, so it asks you to judge each result yourself.
Magic ToDo exports to Todoist, TickTick, Notion, Asana and Amazing Marvin, or saves to iCal tasks, iCal events or Markdown. Pick iCal events and your top-level tasks get lined up on tomorrow's calendar from 9 a.m., which Goblin Tools itself labels a suggested schedule.
Motion: AI that drafts work projects and then schedules them
Motion is built for work. Its AI turns a prompt like "Create a marketing campaign project" into a draft project you preview before saving. Its help center describes these AI Workflows as templates with task sequences and recommended steps, and says they are not automations. Motion's App Store listing says it is best used on a computer and calls the phone app a companion to the web and desktop versions. You need a subscription after the trial.
Its auto-scheduler can cut a long task into chunks of time so it fits the gaps in your calendar, while the task itself stays a single item. A task with no duration won't get scheduled at all.
You can also ask AI Chat to create tasks, projects or docs in plain language. Its reference page says nothing gets published until you confirm. Each chat uses AI credits, and we couldn't find how many a single task breakdown takes. Credits reset every billing cycle and do not carry over. The Pro AI plan comes with 7,500 credits per seat per month.
Routinery: the AI breakdown happens in Claude or ChatGPT, then the app runs it
Routinery, the app we make, has no AI of its own that splits a new task into steps, as far as its App Store listing, update notes and What's New page show. Routinery AI, added in May 2026, recommends routines based on your past routine data and doesn't split a task you haven't started.
The listing has a section called "Ask ChatGPT or Claude to build it." You connect an assistant to Routinery's MCP server, ask for something like "Make me a 40-minute weekday morning routine," and the routine lands in the app. Routinery shows the exact change and waits for you to approve it before anything is created or edited. The MCP setup page says Claude works on every plan including Free, while ChatGPT needs a paid plan with Developer mode switched on. MCP is free on every Routinery plan, though it needs a Routinery account. Our guide to AI-connected habit and routine apps that work over MCP explains the connection in more detail.
In a saved routine, each step runs on its own timer and a voice reads out the next one. The order is set when you build the routine. There is no web version. The listing suggests steps of 1 to 5 minutes, and if you don't use Claude or ChatGPT, you can run the task through Goblin Tools' Magic ToDo and type its steps in by hand.
Tiimo: breakdown inside a visual planner aimed at executive function
You speak or type what's on your mind to Tiimo's AI Co-Planner, and it splits that into steps with time estimates before helping you build a plan. The App Store listing bills the app as "your AI planning partner that simplifies executive function, focus and productivity." Google Play puts it as "AI breakdown of tasks to help you get started."
Those steps go onto Tiimo's color-coded visual schedule, next to a brain-dump to-do list with AI priority grouping. When a scheduled task begins, the focus timer starts by itself. The free plan includes limited AI chats in the phone apps. We could not find out how many. Tiimo shows its Pro price at checkout, so we have left the amount out of the table.
Todoist: Task Assist for people who already live in Todoist
Todoist's Task Assist breaks complex tasks down into sub-tasks, and it is only on the Pro and Business plans. It can also suggest tasks to reach a goal and offer tips for finishing one. Vague tasks get rewritten into something you can act on.
It's off by default. We could not confirm a built-in timer. To switch Task Assist on, you set up the extension in Todoist on the web or in a desktop app, which adds a step for anyone who only uses the phone.
On the free plan you can still split a task into sub-tasks by hand, since sub-tasks are a standard feature. Ramble turns spoken notes into tasks with projects and due dates but does not break them down.
How to choose: start from what you'll do with the steps
- If a single task has you frozen right now and you don't want to pay, open Goblin Tools' Magic ToDo on the web.
- Tiimo fits if you want the steps placed on a visual day with a timer that starts itself.
- Already paying for Todoist Pro? Turn on Task Assist before adding another app.
- Running deadline-driven projects at a computer most of the day suits Motion.
- For a recurring sequence, like a morning or a study block, where you want a voice and a timer walking you through it, have Claude or ChatGPT draft the routine in Routinery, or paste in Magic ToDo's steps.
Because Magic ToDo exports, the list you write in Goblin Tools can end up in Todoist or one of the other apps it supports.
Getting started: test one breakdown this week
Pick the task that has sat on your list longest and run it through one tool tonight. Set the detail finer than feels necessary. Then read the steps and cut any that do not match your actual kitchen, desk or inbox, because the experts in the Dahò study flagged exactly that kind of mismatch in AI plans.
Shrink the first step until it barely counts. Routinery's App Store listing uses "sit at the desk, 1 min" as its example of a step small enough to begin. If you've got the list and still can't move, our roundup of apps for task paralysis covers that.
Frequently asked questions: AI task breakdown apps
Which AI app breaks a big task into small steps for people with executive dysfunction?
Goblin Tools' Magic ToDo is built for exactly this. Type the task and it writes the steps, with a spiciness setting for how fine to cut them. The website is free with no ads. Tiimo's AI Co-Planner does the same inside a visual planner and adds time estimates, with limited AI chats on the free plan. Todoist's Task Assist breaks tasks into sub-tasks for Pro and Business users. Motion's AI drafts work projects. For Routinery, the splitting happens in Claude or ChatGPT, as the Routinery section above explains.
Is there a free AI task breakdown app?
Yes. The Goblin Tools website is free, with no ads or paywalls, and Magic ToDo is one of its tools. The phone apps cost $0.99 once. Tiimo's free plan includes a basic planner with limited AI chats, so you can try some AI planning before paying, though we couldn't find how many chats you get. Todoist's Task Assist needs Pro. Motion has a 7-day trial and no free plan.
Can ChatGPT or Claude break down tasks for me?
They can write steps for any task you describe, and some apps let them save the result. Routinery connects to both over its MCP server, so you can ask for a routine like a 40-minute weekday morning and approve it before it is added. Claude works with it on any plan, including Free. ChatGPT needs a paid plan with Developer mode. Without a connection, you can still copy the steps from a chat into whichever list or timer app you use.
Are AI-generated task steps accurate?
They can be wrong, so read them as a draft. Goblin Tools says its tools run on general purpose models whose accuracy varies and calls their answers guesswork. In a 2025 study, 27 specialists reviewed ChatGPT-written executive function plans for hypothetical people with ADHD, and they rated the plans weak on personalization and feasibility. Motion and Routinery both make you confirm before AI-drafted items are saved. Delete any step that doesn't fit your situation, and add the specifics the AI had no way of knowing.
Does Routinery have AI that breaks down tasks?
Not inside the app, as far as we could confirm from its App Store listing, update notes and What's New page. Routinery AI recommends routines based on your past routine data. To have AI write the steps, connect Claude or ChatGPT to Routinery over MCP and ask it to build a routine, which you approve before it is saved. Routinery then runs each step on its own timer with a voice calling out the next one. The free plan covers 2 routines with up to 10 tasks each.
