Structuring transcripts for RAG and tools
Segment-level text, metadata, and IDs—what to send to your vector store vs. what to keep in your app state.
Retrieval-augmented generation works best when chunks are meaningful. For video, that often means segment boundaries, not arbitrary character counts—so quotes and citations line up with what the user saw.
When you call an API that returns timed segments, you can map each chunk to a stable id, embed the text, and store the video id alongside for reranking or UI deep links.
Keep your pipeline simple:
- Normalize on the API side
- Transform once in your worker
- Let the LLM see clean strings
We designed responses to make that path obvious in the playground and docs.
