Subra AI: Private Workspace

Subra AI is a private AI workspace for people who cannot risk sending sensitive information to a cloud AI service. Use local AI to understand documents, organize records, transcribe voice, and ask questions inside private Spaces. Your personal content is processed on your device by default, with remote processing used only when you explicitly choose it. Built for real-world privacy needs • Caregivers organizing medical records and family information • People reviewing lab reports, prescriptions, and sensitive health notes • Therapists, counselors, coaches, lawyers, and other confidential professionals • Journalists, researchers, and field workers handling sensitive interviews and source notes • Digital nomads and travelers working with leases, visas, tickets, menus, and travel documents • Students learning from textbooks, notes, images, and lecture recordings Private Spaces for focused work Create Spaces for different parts of your life and work. Each Space can keep its own chats, documents, settings, and local records. Use Spaces for: • Health and caregiver records • Professional documents and confidential notes • Travel plans and important documents • Learning materials and revision • Personal projects and private research Work offline after setup Download the on-device AI model once and use core AI features without an internet connection. This is useful on flights, in rural areas, during travel, or wherever connectivity is limited. The initial model download requires internet access and significant device storage. App updates, model updates, and optional content synchronization may also require a connection. Your local Document Vault Import PDFs, images, text notes, and audio recordings into a local Vault.

We do not claim that the entire app is permanently offline: downloads, updates, optional synchronization, and any remote provider you explicitly configure may require network access. Subra AI helps you work with sensitive information more privately—at home, at work, while traveling, and offline.
