Most people forget 80% of a conversation within 48 hours. DIANE remembers everything. Dale Carnegie wrote that every person's favorite word in the world is their own name. The people who make you feel truly seen — who remember your birthday, ask about your sister, recall what you mentioned in passing six months ago — those are the people you never forget. DIANE gives you that superpower. DIANE is your personal AI relationship manager. She remembers the people in your life — their names, their stories, their birthdays, how you met, what you talked about, what you want to follow up on — so you can show up for them the way they deserve. HOW IT WORKS Just talk. After a coffee meeting, a dinner, a phone call — open DIANE and speak. "Had lunch with Marcus today. He's going through a rough patch at work, just moved to Austin, his daughter's birthday is in April." DIANE transcribes your words and builds a rich contact profile automatically. Then ask anything. "What did Marcus mention about his job?" "Who do I know in Austin?" "Whose birthday is coming up?" DIANE searches everything you've shared and gives you a real answer — because she knows your actual contacts, not a scrubbed or anonymized version of them. Never miss a moment. Birthdays, anniversaries, key events — DIANE reminds you a week ahead so you always show up on time with something personal to say.
