ostinata lets you map the actual paths you take through music. ever gone from radiohead to aphex twin because kid a changed how you think about electronic music? from miles davis to j dilla because someone sampled a love supreme? ostinata turns those invisible threads into visual, shareable directed graphs. — how it works — create a journey by adding nodes — artists, albums, genres, emotions, or concepts. connect them with directed edges that show which discovery led to which. add reasoning text to explain the connection. the result is a map of your taste that others can explore, fork, and build on. — search & discover — search for artists and albums via musicbrainz, the open music encyclopedia. album nodes display cover art. long-press any node to open its musicbrainz page for deeper exploration. — fork & remix — see a journey that resonates? fork it. you get a copy of the entire graph — all nodes, edges, and reasoning — that you can extend, rearrange, or take in a completely different direction. — bounties — post discovery challenges for the community. set a topic like "find the link: kraftwerk to detroit techno," define seed nodes as starting points, and offer resonance as a reward. other users form guilds of five to tackle the challenge together. — your data, your cloud — everything syncs privately via icloud. we store nothing on our servers. your journeys, your data, your control. — design — black canvas. white lines. ibm plex mono. all lowercase. album art in grayscale. ostinata is built for people who care about how things look as much as how they sound. ostinata — discovery through human curation.
