It shows you what: 8:10 drop-off, 5:45 dinner, a wall of colored blocks. It knows nothing about why — so every change is a small gamble.
Same afternoon, two calendars. One is a block of color. The other can defend itself — everything on the right is the real engine, running.
What — any calendar
Move anything anywhere. Good luck.
Why — Tiem
June's nap is never interrupted
June naps in her own crib all five days. No car transfers, no cut-short naps.
The nap knows why it's there — and every future edit is checked against it.
Hand one parent an extra school run and Tiem answers with the rule your family set — calmly, and with the numbers.
What if Friday's pickup moved to Jon?
Because Tiem understands the week's structure, it can see the gaps — and puts your breathing room on the calendar like it matters.
01
Your schedule is a living set of agreements — a protected nap, an even driving split, a caregiver's hour cap. An edit that would break one is caught before it saves, not discovered at bedtime.
02
Every event can say why it's there. Expand it and read the rule protecting it — and the reasoning behind the rule — straight off the schedule.
03
Try any change safely in a what-if draft: see exactly which events move, what breaks, and what you gain — then apply it or throw it away.
Most AI features bolt a chatbot onto a pile of events and hope. Tiem's assistant sits on a schedule that already knows the rules, the reasons, and the ripple effects — so the engine does the thinking, and the AI just does the talking.
Can Jon take Friday's pickup?
Not without breaking a rule you set: Duty split is uneven: Jon has 5 runs, Mara has 3 ("driving splits evenly between the parents") Want me to stage it as a what-if so you can see it anyway?
Why is June's nap 11:00–14:30?
It's protected: June naps in her own crib all five days. No car transfers, no cut-short naps.

About 40 conversations with the built-in assistant a month, included with every plan — enough to check the week, ask why an event landed where it did, or try a what-if, without watching a meter.
Connect your own AI provider and API key and the monthly cap doesn't apply — your usage, your billing, no limit from us. This runs through the same pluggable adapter the built-in assistant uses, so switching providers is a setting, not a rewrite.

Tiem is made by Erin, founder of opensetconsulting.com, and Nick, founder of endash.us. Two parents who wanted their own week to defend itself.
