About

Second Brain Link

Read full description

Second Brain Link turns the data you already own into a private, AI-queryable "digital twin" that lives entirely on your device. Your LinkedIn, Facebook, Instagram, and Google exports are unpacked, de-duplicated, and linked into one knowledge graph โ€” right on your phone. Nothing is uploaded. There's no account, no tracking, and no cloud. WHAT YOU CAN DO โ€ข Build your brain from the data exports you request from each platform โ€ข Explore an interactive graph of the people, companies, and topics in your life โ€ข Talk to your twin โ€” ask questions and get answers grounded in your own notes โ€ข Keep everything 100% on-device and private by design WHY IT MATTERS Your most valuable context โ€” who you know, what you've done, what you care about โ€” 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.
