anyproto/anytype-ts

A personal knowledge store where the objects live locally and encrypted, and the sync layer is a network you can point elsewhere or self-host rather than a vendor silo — the brief's "personal and organisational data stores" category, and it passes the can-you-leave test because the local repository is the source of truth rather than a cache of one. The fit is loose in one direction: there is no AI in it, so this counts via the data half of the boundary only. It still counts because this is exactly the corpus AI products want round-tripped, and the architecture answers that.
