A source is raw material: a two-hour transcript, a client email, a saved article. It becomes useful only after something extracts, connects, and files the useful parts where future work can find them. Capture stays separate from processing: a script can collect sources all day without AI, and AI earns its keep at transcript processing, extraction, summarization, and routing.
The intake tray on a desk works the same way. Mail lands there before anyone decides what it means: a bill, a signed agreement, junk, something that needs a reply. Everything in the tray is raw material waiting to be sorted.
Why you care
AI can only reason from what it can see; if the source is missing, the agent guesses. A vault is one common home for processed sources: the raw transcript stays as evidence while the meeting note, person note, and decision note carry the useful parts into a clean knowledge base. Retrieval like RAG only helps when there’s something trustworthy to retrieve. AI work is only as grounded as the raw material underneath it.
