Synapse Notes vs Second Brain Link

Synaps Notes is a private, on-device note app built for local AI. Write and organize notes directly on your iPhone. Chat with your own notes and documents using local AI models. Import PDFs, images, and text files with OCR support. Keep your data on-device by default, with optional Google Drive backup. No account is required to use the core features

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 — right on your phone. Nothing is uploaded. There's no account, no tracking, and no cloud. 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 notes • 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.
