Could you build this?
Partial Notes and a whiteboard UI are vibe-codeable, but a true zero-knowledge encrypted system with real-time collaborative sync requires careful cryptographic design that is easy to get wrong.
What it would actually take: The stack would be a client-side encryption layer (e.g., libsodium or WebCrypto) with keys derived on-device, an encrypted sync backend that stores only ciphertext, and a CRDT-based library for conflict-free collaborative whiteboard editing. The hard parts are key management and recovery without the server seeing plaintext, and making real-time sync of encrypted, mergeable whiteboard state work reliably. That calls for an engineer with applied cryptography and collaborative-editing experience, plus a security review before trusting it with user data.
