We built notbumblebee: a lo-fi track generator that automatically finds the perfect movie dialogue and composes a complete track around it. Type a vibe like "forest coffee" or "midnight drive," and get a full lo-fi beat with a movie quote woven into the arrangement. Lo-fi producers spend hours scrubbing through movie clips hunting for that one perfect soundbite to sample. notbumblebee does the digging by searching 10,000 movie clips from the VoxMovies dataset instantly and generating an original track that fits the quote. turbopuffer powers the retrieval. We use `multi_query` to run BM25 keyword matching and vector ANN over OpenAI text-embedding-3-large embeddings (3072 dimensions) in a single call, then fuse the rankings with Reciprocal Rank Fusion. This finds the right clip from 10,000 candidates in milliseconds — matching both the literal words and the semantic mood of what the user typed. ElevenLabs powers both the music and the data pipeline. Scribe v2 transcribes all 10K movie clips with word-level timestamps, giving us precise dialogue trimming and placement. For music generation, we call `/v1/music/plan` to generate a structured composition plan, then Claude edits it — adding a specific key, BPM, chord progression, and instruments for each section. The edited plan goes to `/v1/music/compose` to produce the full track. Each generation has a real musical arc: atmospheric intro with the dialogue, groove, peak, and outro.
