Eidra is a quiet memory for the people in your life. Tap once. Speak. Or type a few words. The AI listens, extracts the names, places, interests, and follow-ups, and holds them for you. Months later, when you bump into someone and your mind goes blank, you ask Eidra. The answer is already there. WHO IT'S FOR The friend you saw at a dinner party last spring (whose new partner's name you keep almost remembering). The neighbor you've waved at for two years and never quite caught the name of. The mentor you met at a conference whose advice you can never relocate when you need it. Your kid's teacher, your cousin's husband, the barista who knows your order, the new colleague who mentioned a hobby you wanted to ask about. The dating app match whose stories you want to hold onto. The mom of your daughter's classmate. Anyone you've ever wanted to remember a little better. FOR WORK, TOO Sales reps building rapport with prospects across long deal cycles. Founders tracking the people they meet at every dinner, conference, and intro coffee. Recruiters keeping context on candidates and clients. Investors holding onto the threads of every founder pitch. Anyone whose job depends on remembering people well. Eidra is a personal CRM that does not feel like a CRM. The same fast capture, the same effortless recall, just as useful for the prospect you met last quarter as the friend you saw last weekend. WHAT MAKES IT FEEL DIFFERENT Most apps make you do the work of organizing. Eidra does it the moment you speak. You say, "had drinks with Leslie, she just got back from Lisbon and is starting sourdough lessons." Eidra extracts Leslie, the trip, the new interest, and the date. It writes a one-line entry into her timeline. It updates her structured profile so the next time you ask, "what's Leslie been up to," it remembers all of it. Her card even grows with her: as you capture more, Eidra reconciles the details over time, remembers the family and pets around her, and links her to the people she's connected to. It is not a note-taking app. It is not a journal. It is a memory aid that makes the small details feel effortless to keep. WHAT YOU CAN ASK Once you've captured something, you can ask Eidra anything about anyone: • When did I last see Marcus? • What was the name of Sarah's daughter? • Who did I meet last month interested in startups? • What was that book Olivia mentioned? Eidra answers in your own words, the moment you need it. ALSO INSIDE • Important dates & reminders: a calendar of every birthday, anniversary, and follow-up, with an optional heads-up two days before so you never miss one • Connections: link people together and remember how they relate • Family & pets: Eidra quietly remembers the people (and pets) around the people you know • Briefings: a 30-second AI recap before you see someone again • Custom prompts: ask anything specific ("what should I bring up with Eli?") • Hidden contacts: lock private notes behind Face ID • Voice or text capture, your choice every time SUBSCRIPTION TIERS Eidra is free to start, with limits.
