So the extension scrapes all your bookmarks' content, selects key parts of it (we have a naive heuristic for now), embeds them using Sentence Transformer, and indexes them in the browser local storage with Orama's vector DB. When you want to search, we embed the query and do a vector search against the index to get the semantically most similar ones. All in-browser so no data going to any API.
Didn't try victor, is that just for nodejs runtime or does it run at the edge as well? Orama's been pretty good, at least semantically. Haven't done any speed benchmarking so not sure if it's as fast as say HNSW.
