About this app
Turn your LinkedIn, Facebook, Instagram & Google exports into a private AI digital twin — 100% on your device. No account, no cloud, no tracking.
Second Brain Link unpacks the data exports you already own, de-duplicates the people and events inside them, and links everything into one AI-queryable knowledge graph — built right on your phone. Nothing is uploaded. Nothing leaves your device.
WHAT YOU CAN DO
• Build your brain from the data exports you request from each platform
• Explore an interactive graph of the people, companies, and topics in your life
• Talk to your twin — ask questions and get answers grounded in your own data
• Keep everything 100% on-device and private by design
WHY IT MATTERS
Your most valuable context — who you know, what you've done, what you care about — is trapped in export archives nobody ever opens. Second Brain Link hands it back to you, working.
Your data already exists. It's already yours. It's time it started working for you.
