Gemini Embedding 2 lab
Test meaning-based retrieval before adding semantic search to Prism. The experiment compares your question with five fixed, synthetic documents and returns the closest matches.
Privacy boundary: use ordinary test questions only. Nothing is stored, no Dopamine Vault data is accessed, and the embedding vectors are never sent to the browser. This page is not production Prism.

Higher similarity means the embedding model judged the meaning to be closer. It is not proof that the passage is factually correct.
