About

birthdAI

Features

You already knew it was their birthday. The app told you. Now you're staring at an empty chat box, trying not to type "Happy birthday!!" for the ninth year running. birthdAI writes that second part. It imports the birthdays already in your contacts and calendars, reminds you as far ahead as you like, then drafts a message for that specific person — who they are to you, your tone, their language. Then it opens your preferred messaging app with the text ready. You press send. Always you. It never sends anything on your behalf. NO ADS. NOT ONE. No banners, no video to sit through to find out whose birthday it is. UNLIMITED PEOPLE, FREE Every reminder and every template message, for everyone in your life, permanently. No cap at five. Plus adds AI-written messages — your first three people are on us. WRITTEN FOR THE PERSON Ten relationships, four tones, three lengths, six languages. Add notes — inside jokes, how the two of you actually talk — and the draft stops sounding like a greeting card. Don't like it? Try another. REMINDERS THAT FIRE Two weeks ahead to same-day, any combination. Scheduled by your phone, so they work with no signal. NOTHING LEAVES YOUR PHONE No account, no sign-up, no tracking. Your people, their dates, your notes and every message you've sent stay here. Only a first name and your tone choices go out, and only when you ask for a draft.
