Knowledge Base Overview
Every character can have a Knowledge Base: a collection of documents the AI references during conversations using retrieval-augmented generation (RAG). This lets your character speak accurately about specific topics without stuffing everything into the personality prompt.
Supported File Types
Upload documents in any of these formats:
- PDF: manuals, reports, whitepapers
- TXT: plain text notes, transcripts
- MD: Markdown documentation
- CSV: structured data, product catalogs
- JSON: API responses, configuration data
Maximum file size is 10 MB per document. You can upload multiple files: they are all indexed together.
How It Works
When a user asks a question, the AI searches the knowledge base for relevant passages and weaves them into its response. It cites from your documents while staying in character.
Best Practices
- Clean data wins: remove headers, footers, and boilerplate before uploading
- Chunk logically: one topic per document performs better than a single massive file
- Update regularly: delete outdated documents and upload new versions as your content evolves
