press start to sample the open firehose in this tab.
Inspired by @fromthewestmeadow.com's PCA-on-embeddings visualization of their own posts and their mutuals' — this is an independent, live implementation of the same underlying idea, minus the 3D picture. Your browser fetches a small recent-post history, connects directly to Jetstream, and ranks a filtered trickle using local hashed text vectors and cosine similarity. Nothing is sent to a backend or stored by this site; press stop any time to close the stream.

How the scoring actually works: the target's last ~50 posts (via the public AppView, no login) become small hashed text vectors in your browser and are averaged into one centroid vector. The live firehose is filtered down — English, long enough to carry meaning, not obvious spam, one candidate per author per 45 seconds — because the full firehose is far too large to process exhaustively; that filtered trickle is vectorized in bounded batches on a timer and scored against the centroid. The leaderboard keeps the highest-scoring posts seen in roughly the last 6 hours, so it drifts as the firehose does — this is a sample of the firehose, not exhaustive coverage of it. All processing stops when you press stop or close the tab.
