Your personal guide,
always paying attention.
How it works
BD is not a tool you use. It's a relationship that grows.
Tell BD about yourself
A short onboarding conversation. BD asks a few real questions — not forms. It learns your name, your work, your routine, who matters to you.
BD pays attention
Every conversation, BD remembers. The person you mentioned. The deadline you're anxious about. The thing you said you'd follow up on. It builds a picture over time.
BD shows up first
BD doesn't wait to be asked. It checks in when you get home. It follows up on what you shared. It notices when something important is coming up.
Built different
Most AI apps answer questions. BD pays attention.
Persistent memory
BD remembers everything you share — people, goals, worries, wins. It builds a real picture of your life over time, not just your last message.
BD reaches out first
You don't have to open the app for BD to be present. It sends you a message when it matters — not spam, not reminders. Genuine check-ins.
Share anything
Send photos, documents, PDFs. BD sees them, understands them, and remembers them. Show it a problem, an idea, or something that made your day.
Your data stays yours
Everything BD knows about you lives in your personal memory cluster. Private, secure, and yours — not used to train models or sold to anyone.
Dark mode native
BD is built for iOS with full dark mode support. Elegant typography, glass UI, native animations. It feels like it belongs on your phone.
Gets better over time
The longer you use BD, the more it knows you. There's no reset, no starting over. Every conversation adds to who BD understands you to be.
Android is coming
BD is currently available on iOS. Leave your email and we'll notify you the moment the Android version is ready.
