Ask less. Know more. Dvina is a personal AI assistant that knows your world and comes to you first. Connect your email, calendar, files and the apps you use, and Dvina keeps the whole picture in view: who's who, what's planned, what's waiting on you. You spend less time asking, and more time living. KNOWS BEFORE YOU ASK Dvina notices what matters before you think to check. Your passport expires before the trip. A bill is due Friday. A meeting moved. It tells you, with the next step ready for your OK. Once a week, your week arrives in one card: what got done, what was decided, what's still open. SEE IT, DON'T READ IT Ask where your money went and get a chart. Ask when everyone's free and get a calendar. Ask what's left before the move and get a checklist. Dvina answers with the thing that makes it clear at a glance, not a wall of text. YOUR WHOLE WORLD. ONE PLACE. Mail, calendar, files and chats, understood as one. Dvina remembers what matters and keeps it current as your day changes, so every answer starts from what's true for you now. Works with 100+ apps, including Gmail, Google Calendar, Google Drive, Outlook, Slack and Notion. JUST CALL Call Dvina like you'd call a friend. Talk it through with your hands full, with live captions on screen, hang up, and it's handled. DONE WHILE YOU SLEEP Hand off the long work: research, a plan, a draft. Dvina keeps going in the background and the result is waiting when you're back. YOURS ALONE Private by design. Your conversations and documents are never used to train AI models. Sensitive details like card and phone numbers are masked automatically before they reach the AI, and Dvina asks before it does anything personal, like paying a bill or sending a message. EVERYWHERE YOU ARE Start on your phone, pick it up on your computer. It's one Dvina, wherever you are.
