Partial The chat UI and self-deleting notes are vibe-codeable, but end-to-end encryption that is actually secure requires careful key management and a security review that vibe coding alone won't provide.
What it would actually take: The UI, storage, and notification layers can be built with a mobile framework and a realtime backend. The hard part is a vetted E2E protocol (for example, a Signal-style double ratchet using libsodium or similar), safe key handling, and metadata minimization. A credible version needs an experienced applied cryptographer or security engineer and an independent audit before anyone trusts it with private messages.
