See how retrieval augmented generation actually works.

Load a chat transcript or a document, then watch Chunkie cut it into chunks, turn each chunk into 384 numbers, and search them by meaning as you type. Every step is on screen, nothing is uploaded, and a written guide explains the ideas behind it.
