Stop herding people. Just text Chrono.
Chrono is a clock-dog who finds a time that works for everyone. Add the people you want to see, and Chrono asks them when they're free, in a normal text conversation. No app to install. No links to copy. No spreadsheets.
US toll-free SMS · Replies are free · Reply STOP any time

Three steps. Nobody has to learn anything new.
The whole point is that it feels like texting a friend who\u2019s really good at scheduling.
- 01Step 1 of 3
Tell Chrono what you’re planning
Title, rough duration, and the people you want to invite by phone or email. Takes about a minute.
- 02Step 2 of 3
Chrono asks everyone, in plain English
No links, no apps. Each person gets a friendly text. They reply however they normally talk: “saturdays after 6”, “the first week of June”, “not mondays”.

A friendly assistant who happens to be a dog
Chrono isn\u2019t an app. There\u2019s no “chatbot” vibe. He\u2019s just there in your messages, getting the time pinned down.
Talks like a person
“Fridays after 6”, “any time the week of the 14th”, “not mornings” — Chrono understands them all.
Knows time zones
Chrono tracks each person’s local time so a 7pm dinner means 7pm wherever they are.
Friendly nudges
If someone says “remind me tomorrow”, Chrono actually does. Quietly. Never spammy.
Privacy-first
Your contacts stay yours. STOP works instantly. Numbers and replies are purged after the event.
The stuff people ask first
Do my friends need to install anything?+
No. Chrono just texts them. They reply like they would to anyone else. If they want a richer view, the message includes a private link they can tap — no signup, no password.
Is this an AI chatbot?+
Chrono isn't trying to be a chatbot. He's a small, focused assistant for one thing: pinning down a time. He understands natural-language replies under the hood, but you'll never feel like you're talking to a robot.
What if someone doesn't want texts from Chrono?+
They reply STOP. That's it. We honor it instantly across every future message, and you'll see them marked as opted out in your dashboard.
How much does it cost?+
Free during the beta. Long-term plan is $1 per event with three free events per host so you can use it casually without a subscription.
Where do you keep my data?+
On Microsoft Azure, in the United States. Phone numbers and replies are kept only as long as the event needs them, then purged automatically.
