Darwin reads the thread, works out when everyone is free, agrees a time like a real person would, and puts it on your calendar. No booking links. No back-and-forth. No app to open.

Sign in with Google so Darwin can see when you're free and put meetings on your calendar. He never reads your email.
One address, darwin@darwinschedules.com. He knows it's you from the address you send from.
He proposes times, handles the replies and the time zones, books it, and follows up if someone goes quiet.
No toggles, no rule builders. You write your preferences in plain words — including the ones no settings page could ever have a checkbox for — and he applies them with judgment.
An assistant that emails people on your behalf should be boringly safe. Darwin's limits are enforced in code — not just asked of the AI.
On personal plans Darwin only writes to people already on your threads — enforced in code, so no personal account can ever be used for spam. Custom-plan assistants on your own domain can make first contact and introductions for you.
Participants are offered times. They never see your events, titles, or who else you're meeting.
Instructions in an email from someone else are treated as data, not orders. Only you can direct your assistant.
Every email offers a one-word opt-out, and he honours it immediately and permanently.
Odd hours, new people, anything ambiguous — he emails you privately instead of guessing.
Your dashboard shows what he did, to whom, and why.
No card, no invoice, no sales call. If it isn't saving you time by day 30, walk away.
Honest comparisons — including the cases where something else is the better tool.
A link shows everyone your whole open calendar and makes them do the work. An assistant offers three good times.
Same briefing, same email thread — at a fraction of the cost, on every thread at once, around the clock.
Where the AI schedulers differ: what they can read, what they're allowed to do, and what's enforced rather than promised.
Why an email-reading assistant must be safe by architecture, not by asking the AI nicely — and how Darwin is built.
No. Darwin has his own mailbox. He only ever sees the threads you deliberately CC him on — nothing else in your inbox. We never ask for access to your Gmail.
He checks when you're busy and creates the events you agree to. Meeting participants only ever receive proposed times.
On the personal plan he replies on threads that already exist, to people already on them — a guardrail that keeps the shared sending domain clean for everyone. On the Custom plan your Darwin sends from your own domain, so he can open fresh threads: introductions, first outreach to a candidate, chasing someone who never replied.
He stops scheduling and we email you. Nothing is deleted, and you can pick up where you left off.
Yes — your dashboard lists every thread he's working, every email he sent, and every meeting he booked.
