Private beta Β· Spring 2026

Your calendar,
in your inbox.

OysterPal is a calendar you talk to like a friend. Email it your plans β€” "dinner with Sam, Friday 7pm" β€” and it remembers, reminds, and replies on the same thread. No app. No login. No syntax to learn.

Free during beta. We'll only email you when there's a real invite.

How it works

Three steps. Zero apps.

Send an email. OysterPal keeps it safe like a pearl in a shell. The rest happens on its own.

i.

Email it

Send a note to like you'd text a friend. "Dentist Tuesday 3pm." "Lunch with Priya next Friday."

ii.

We remember

OysterPal reads it, picks out the date, time, and details, and saves the event. You get a reply confirming what it heard.

iii.

It nudges back

Reminders arrive on the same email thread, day-of. Need to change plans? Just reply. Cancel, move, push, swap β€” natural language only.

Why OysterPal

The calendar that gets out of the way.

No app, no login

If you have email, you have OysterPal. Works on any phone, any laptop, any client. Forever.

✦

Talk like a person

"Push my Friday dinner to 8." "Cancel Thursday." OysterPal figures out which event you mean.

FAQ

Common questions.

How is this different from Google Calendar?

You don't open an app. You email a friend named OysterPal. It remembers everything you tell it and nudges you on the day. Google Calendar wants you in its UI; OysterPal stays out of your way.

Is my data private?

OysterPal only reads emails you send to its address. Nothing else in your inbox is touched. We don't sell data, we don't train models on your plans.

What about conflicts and reminders?

Same-day overlaps get flagged automatically. Reminders fire the morning of an event, on the original email thread, so context stays together.

When can I use it?

We're rolling out invites through the spring. Drop your email below and we'll send you one when there's a slot.

Will it cost anything?

Free during beta. Long-term we're aiming for under $5/month for personal use β€” the kind of thing you'd pay for an extra streaming service and forget about.

Can it sync with my real calendar?

Not at launch. Google Calendar sync is on the roadmap right after MVP β€” it's the most-asked-for feature already.

Be one of the first.

We're sending invites in waves. Early users help shape what OysterPal becomes β€” and you'll never have to pay for the version we ship at the end.

No spam. No marketing. One email when your invite is ready.
