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
Wren's nap is never interrupted
Wren 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.
Tiem is a website first — open it in any browser, on any device, right now. Add it to your home screen and it behaves like a real app: its own icon, its own window, no address bar. No app store between you and your week, on either side.
→
One codebase, every device: phone, tablet, laptop, whatever a given parent or caregiver happens to be holding. If it has a browser, it has Tiem.
→
Add it to your home screen and it opens standalone — its own icon, no browser chrome — and keeps working from the last screen you were on, even with a spotty connection.
→
Nothing to submit for review, nothing you have to remember to update, nothing gatekeeping who gets to install it. It's just the web, doing what it was always supposed to do.
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 Wren's nap 11:00–14:30?
It's protected: Wren naps in her own crib all five days. No car transfers, no cut-short naps.

Join the waitlist below to hear the moment it lands.
Basic AI answers straight from your household's own context graph — why an event exists, what today looks like, whether a change would break a rule. It's on-device, deterministic intelligence: no hosted model call, so it costs nothing and never leaves your data. That's why it's unlimited on every plan, including the free plan.
Week optimization, reading a shared document, planning several moves ahead — these call a frontier language model, which costs real tokens. That deeper tier is metered on the paid plan, and it's the one bring-your-own-AI replaces if you'd rather run it on your own key and billing.
Connect your own AI provider and API key and the frontier tier runs on your own billing instead of ours — no meter from us either way. Basic AI is unmetered and unchanged regardless: it never calls a hosted model in the first place.
Sign-up and billing aren't live yet — join the waitlist below and we'll reach out before anything is charged.
Sign-up isn't open yet — leave your email and we'll let you know the moment it is. Nothing is charged before then.
Questions first? hello@tiem.app — a person reads it.
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.
