For couples (and families). Especially the forgetful one.
Never hear “wait, that was today?!” again.
Try it. Pick a tone.
Not every couple wants the same kind of nudge. Tap around — this is what lands in both your inboxes.
💕 Wedding Anniversary
⏳ 5 days and counting…
Your anniversary is in 5 days. That's enough time to plan something wonderful, or enough time to panic. We recommend the first one.
🎯 Your mission, should you choose to accept it
Book dinner at the place from your first date
Real flowers. A florist. Not the gas station.
Write a card with visible effort
Notes: Likes Italian food, candles, and anything that looks like effort was involved.
💡 Ideas, if you're stuck
• Reserve the corner table at Lucca's — she mentioned it twice
• A beeswax candle set, not the scented-aisle kind
• Frame the photo from the first-date trip
One tap, no login
Claim it and the other one gets told to stand down. No duplicate flowers.
✨ The message inside the buttons? Already written. You're welcome.
Sample emails. The real ones are written fresh by AI every time — so no two reminders are the same.
New · included in every plan
Remembered it? Now send the card.
One tap from any date — or straight from the reminder email. Pick a design, let the AI write it in your voice (sweet, funny, a loving roast), and send. They get an envelope that opens on their phone, with a little animated surprise inside.
Then the part nobody else does: you get an email when they open it, and when they tap ❤️ 😂 🥹 🤗 back.
Built for real couples with real calendars
Loving someone is easy. Remembering their mother's birthday is a software problem. We solved it.
Built for two. Or three. Or the whole family.
One shared calendar for your household — up to 5 people. Anyone adds a date, everyone gets the reminder email. Democracy.
AI writes every email
Each reminder is freshly written — a new joke (or a sweet note, your choice), every single time.
Pick your tone
Sweet, Funny, Mild Roast, Maximum Chaos, or No Jokes Just Remind Me. Your relationship, your vibe.
One-tap damage control
Emails come with Call, Text, and Email buttons — with a heartfelt message already written. Press send, take the credit.
Set once, reminded forever
Birthdays and anniversaries repeat yearly on their own. Forget about remembering to remember.
“I've got this” — one tap
Claim a date from the email and everyone else is told to stand down. No two bouquets, no zero bouquets. Nudge, snooze, or mark it done without logging in.
Notes, tasks & real ideas
“Likes Italian food, candles, and visible effort.” Your to-dos arrive as a checklist, plus three concrete gift ideas from the AI — not “get a gift card.”
Send a card that opens
One tap from any date or reminder. AI writes it, you tweak it, they get an animated envelope — and you hear back when they open it.
You'll know it landed
Opened? Loved it? Laughed? Their reaction comes straight back to your inbox. No more “did you get my card?”
How DateKeeper works
Paste your dates
A list, a text from your mom, notes from your phone — the AI turns it into dates with reminders in one go. Or add them one at a time.
Add the details
Who it's for, what needs doing, gift ideas, dinner plans — anything your future self needs.
Choose when to be reminded
A month before, a week, a day — or the exact date and time you pick.
Everyone gets the email
Both of you, all three of you, the whole family. Nobody has to say “wait, that was today?” ever again.
A note from the person who built this
Hi, I'm Ghatzby. I built DateKeeper for my own marriage. One of us remembers every birthday, every in-law, every “we should do something for that.” The other one of us is a wonderful person who has, more than once, said “wait, that was today?”
Shared calendars didn't fix it — nobody opens a calendar. What fixed it was an email that shows up a week early, tells you exactly what to do, and is funny enough that you actually read it. So I made that. We use it every day, and now it's yours too.
It's just me behind this, so if something's off, email me — I'll answer personally.

For anyone who wants fewer “you forgot?” conversations.
Private by design
Your important dates can be personal. DateKeeper treats them that way. We only use your information to send your reminders — we don't sell your data, and we don't share your relationship details. Your birthdays, anniversaries, trips, and family reminders stay between you, your partner, and DateKeeper.
You can edit or delete your dates anytime. Read the full privacy policy →
Frequently asked questions
Can all of us add dates?＋
Yes. Everyone in the household can add, edit, and manage important dates in one shared calendar.
Will all of us get the email reminder?＋
Yes. Every reminder goes to every member's inbox, so nobody has an excuse.
Can I choose when reminders are sent?＋
Yes. Use the presets (1 month, 1 week, 1 day before — sent at 9 AM) or pick any custom date and time. Each date can have as many reminders as you like.
Are the emails always funny?＋
Only if you want them to be. Choose your tone in Settings: Sweet, Funny, Mild Roast, Maximum Chaos, or No Jokes Just Remind Me.
How much does DateKeeper cost?＋
Your first 14 days are free — no credit card required to start. After that it's $20/year for your whole household — up to 5 people: unlimited dates, unlimited reminders, unlimited cards, and all the AI features. That's the founding price: the first 100 households keep it for as long as they stay subscribed.
Is my data private?＋
Yes. Your dates are only used to send your reminders. We don't sell your data or share your relationship details. You can edit or delete your dates anytime.
What stops us from both buying flowers?＋
Every reminder email has an “I've got this” button. Tap it and the other person's reminders change to “Sam's handling it — nothing for you to do.” There's also Nudge (poke your partner), Remind me tomorrow, and Done. All one tap, no login. If nobody's claimed it two days out, the email says so.
What's the card thing?＋
From any date (or right inside the reminder email) tap “Send a card.” Pick one of six designs, let the AI draft the message in your tone, and send. They get an email with an “Open your card” button that opens an animated envelope with a GIF inside. You get an email when they open it and when they tap a reaction. Unlimited, included in the plan.
Is it only for couples? What about families?＋
Couples are who we built it for, but a household is just the people who share your calendar — you and your kids, you and your parents, the whole family. One plan covers up to 5 people. Everyone gets the reminders, anyone can send a card.
Can I invite people later?＋
Yes. Create your account first — you'll get an invite link on the Settings page to share whenever they're ready.
