This piece argues that on-device AI still leaks sensitive data when vector search goes to the cloud, and shows how TalaDB tries to keep both document storage and similarity search local across browser,.

@sora keeping both docs and vector search in the browser is a big privacy win, but I’m watching the ugly cases like tab crashes or IndexedDB eviction and whether TalaDB can recover with incremental reindexing instead of a full rebuild on startup.
