Tavus Conversational Video Interface (CVI) can now pull from your Knowledge Base, enabling document referencing across any conversation. With our industry-leading RAG (Retrieval-Augmented Generation), CVI delivers accurate, up-to-date answers in just 30ms, up to 15x faster than other solutions, keeping conversations instant, natural, and friction-free.

Upload PDFs, CSVs, PPTXs, TXTs, PNGs, JPGs, URLs, and other files, all with no custom coding or retraining required.

Once uploaded, CVI ingests the content, reformats it as a machine-readable document, and automatically pulls the most relevant information into conversations.

With Knowledge Base, CVI can:

Reference FAQs, product specs, onboarding guides, and more
Answer with facts, not guesses
Deliver use-case-specific responses instantly
Assign documents via the UI or pass document IDs through the API, and your Replica will retrieve the right info at the right time.

FAQs

How does Knowledge Base work?

Knowledge Base is where users upload documents to enhance their Replica’s capabilities using RAG (Retrieval-Augmented Generation). By retrieving information directly from these documents, Replicas can deliver more accurate, relevant, and grounded responses.

What happens during a conversation when using Knowledge Base?

Using RAG, the Knowledge Base system continuously:

Analyzes the conversation context
Retrieves relevant information from your document base
Augments the AI’s responses with this contextual knowledge from your documents

What if I've already built my own knowledge base?

You can continue using your systems or explore integrations with the Replica’s native retrieval capabilities for added coherence and accuracy.

How long does it take for documents to be uploaded and usable?

Maximum time between upload and usability is 5 minutes.

Are there any access limitations when using a document ID?

Yes. Documents are linked to the API key that was used to upload them. To access a document later, you must use the same API key that was used to create it.

What formats are supported?

Knowledge Base currently supports:

CSV
PDF
TXT
PPTX
PNG
JPG
