Partial The UI and PWA shell are easy, but a real zero-knowledge, local-first service needs correct encryption, sync conflict resolution, and sharing, where subtle security mistakes are likely without cryptography expertise.
What it would actually take: A realistic build uses a PWA with IndexedDB or OPFS for local storage, a compression step, and client-side encryption with keys derived in the browser (e.g., via WebCrypto). Sharing and multi-device sync require a key-exchange scheme and a sync protocol with conflict handling, which is where expertise in applied cryptography and distributed systems is needed. The claimed 20% storage savings is a compression detail that is only a minor part of the difficulty.
