The Anytype model is really cool - in a way, they’ve rebuilt Lotus Notes with 21st century E2E encrypted protocols and technology. They’ve built a really solid personal knowledge app with many of Notion’s features - and some clear improvements over Notion.
However they also demonstrate the complexity and tradeoffs of the E2E approach. Anytype has been a work-in-progress since at least 2019. Their docs still state:
> Future versions will allow you to share your work and safely collaborate with others
> There's no browser version of the app. Anytype is a stand-alone software, that works on desktop or mobile devices. There are many points of vulnerability in-browser apps that would compromise our commitment to data security and encryption.
Without these features Anytype is in a much smaller market (PKM) with less distribution than Notion/Coda/Dropbox Paper/Quip/Confluence/…
