Ask the shared corpus.

Knowlex chunks whatever you paste in Corpus, embeds each chunk with gemini-embedding-001 (truncated to 768-dim), stores the vector in pgvector, and answers your question by retrieving the top-K chunks via cosine kNN and streaming a grounded Gemini 2.5 Flash reply with numbered citations.

Answer

Grounded answers with [n] citations land here.

Grounded by construction

The system prompt forbids outside knowledge. If retrieval misses, the model says so.

Cite-by-number

Each chunk gets a [n] reference. The model quotes them inline; the panel shows titles.
