AI · comparison
The best AI to-do apps, sorted by what the AI actually does.
Disclosure: Brainspill is our app. The category framing below is honest — if your bottleneck is scheduling rather than capture, Brainspill is not the answer and we say so.
First, find your bottleneck
Ask where your system actually breaks:
- “Things never make it INTO my list” → capture problem → AI capture app (Brainspill).
- “My list is fine but my calendar is chaos” → scheduling problem → AI scheduler (Motion, Reclaim).
- “My tasks, notes, and ideas are scattered everywhere” → consolidation problem → AI assistant (Saner.AI).
- “I want my current system, just smarter” → structured manager with AI (Todoist).
Most “best AI to-do list” roundups rank these against each other as if they were interchangeable. They are not — an AI scheduler cannot fix a capture problem, and vice versa.
AI capture: Brainspill
What the AI does: eliminates typing. You speak the way you think; Brainspill splits the ramble into tasks, events, and reminders with dates and categories, then syncs them into Apple Reminders. The AI also works on the doing side: “what’s next?” picks your next task and tells you why; “I’m stuck” breaks the scary task into tiny first steps.
Two things are unique in this field:
- On-device AI. Audio never leaves your phone, and on Apple Intelligence iPhones the task extraction itself runs on-device — on every tier. Every other app on this page sends your content to a server. If the idea of your half-formed thoughts as API traffic bothers you, this is the only option.
- No new system. The output lands in Apple’s own apps, so you are not migrating your life into a startup’s database.
Free tier: a 2-minute spill daily. iPhone only.
AI schedulers: Motion and Reclaim
What the AI does: builds your calendar. Feed in tasks, priorities, deadlines, and meetings; the AI time-blocks your day and reshuffles automatically when things slip.
- Motion is the maximalist: projects, dependencies, team scheduling. Powerful, and priced like a work tool — $19 per seat monthly, about a third less billed annually, with a trial rather than a free tier.
- Reclaim plugs into your Google or Outlook calendar and defends time for habits and tasks; a free-forever Lite tier makes it the low-risk trial.
Both assume tasks are already captured and well-formed — the exact step they do nothing about.
AI assistant: Saner.AI
What the AI does: consolidates. Saner.AI treats tasks, notes, and emails as one searchable pool with an assistant on top — closer to “AI chief of staff” than to-do list. Compelling if your problem is scatter; heavier than a task app if it is not. Its own site now bills it as an AI personal assistant for ADHD specifically.
Classic manager with AI: Todoist
What the AI does: assists at the edges. Todoist remains the benchmark structured task manager, and its AI Assistant plus the Ramble voice-capture feature (10 sessions a month free, unlimited on Pro at $48/year) retrofit intelligence onto a proven system. The AI is additive rather than transformative — which is exactly right for people who already trust their Todoist setup.
Also seen in roundups: Taskade (AI agents and workspace generation — a team workspace more than a personal to-do list) and ClickUp (work management suite; its AI targets teams and docs). Both are bigger hammers than a personal task list needs.
Side by side
| App | The AI’s job | Runs on-device | Output lives in | Free tier |
|---|---|---|---|---|
| Brainspill | Voice → organized tasks | Yes | Apple Reminders + Brainspill | 2-min spill daily |
| Motion | Auto-schedule your day | No | Motion | Trial only |
| Reclaim | Defend calendar time | No | Google/Outlook Calendar | Yes |
| Saner.AI | Assistant over tasks + notes | No | Saner.AI | Yes |
| Todoist | Assist + voice capture | No | Todoist | Yes |
Questions, answered
What does an AI to-do list actually do?
One of four things: captures tasks from natural speech or text (Brainspill, Todoist Ramble), schedules tasks onto your calendar (Motion, Reclaim), acts as an assistant across tasks and notes (Saner.AI), or adds smart suggestions to a classic manager (Todoist AI Assistant). No mainstream app does all four well.
Which AI to-do apps keep my data on my device?
Brainspill is the only one in this comparison that processes on-device (Apple Intelligence on supported iPhones) — and regardless of device, it never uploads your audio. The rest process your content on their servers.
Do I need an AI to-do app at all?
If plain Reminders or Todoist already works for you — no. AI earns its place when a specific step keeps failing: thoughts not getting captured, or a calendar that never matches the plan.
