Kaï is your built-in AI assistant, running 100% on your device. It helps you build your day, estimate how long tasks will take and break big tasks into steps — without ever deciding for you.
How to do it
1Turn Kaï on in Settings › My Kaï assistant. On first launch, a small model downloads onto your device.
2From My Day, tap “Plan with Kaï”: it builds your day from your pending tasks, the urgent ones first, around your fixed slots.
3Rearrange as you like, pin a task to lock it in place, or regenerate the plan — you're always in control.
4On a task, ask Kaï to estimate the duration or break it into steps, then confirm the result.
Tips
Kaï adapts to your energy: 2 tasks in survival mode, 3 when focused, 5 at full energy.
Add your preferences in “Notes for Kaï” (200 characters max) — it factors them into every suggestion.
Duration estimates appear after about twenty timed sessions, once Kaï knows you well enough.
It can pull small tasks from the Brain Dump to fill gaps, and treats your appointments and routines as fixed slots.

Good to know
Local-first: Kaï runs entirely on your device — no API, no server, no logs. On the free plan, daily quotas apply (e.g. 1 plan and 10 estimates per day); Premium unlocks them with no limit.
