The zero-knowledge architecture is crucial for this use case. One thing I've been contemplating while building PrivaVault (launching next week) is the tension between E2EE and search/organization features. Users need to find their documents quickly, but you can't build server-side search if you can't read the content.

We ended up implementing client-side encrypted search indices that sync across devices—adds complexity but preserves the zero-knowledge guarantee. Curious how Agam Space handles this? The demo looks clean, but I couldn't tell if search works on encrypted content or just filenames.
