Knowledge Base (RAG)
Upload text or files when creating or editing an NPC. Mistscale splits the content into chunks, embeds them, and retrieves the relevant pieces every time the NPC speaks, so answers stay grounded in your canonical lore.

How an upload progresses
Each uploaded file passes through these statuses, visible as a colored badge next to the file in the NPC editor:
pendingFile received, waiting in the processing queue.
processingBeing chunked and embedded. Usually completes within seconds to a minute.
readyIndexed. The NPC draws from it on the next reply.
failedProcessing failed. Delete and re-upload.
Limits
- Up to 3 knowledge files per NPC by default.
- Text or single-file uploads. No bulk import in the current UI.
- Deleting a file removes both the original and every embedded chunk derived from it.
What makes a good knowledge file
Self-contained, narrative or factual prose works best. Lore documents, character bibles, location descriptions, in-world manuals. Avoid raw spreadsheets, code, or fragmented bullet dumps. They index poorly and produce shallow answers.
