Make your AI assistant answer only from what each person may see
Description and use
<p><iframe src="https://player.vimeo.com/video/1239159340" width="710" height="399"> </iframe> </p> <p>An AI assistant answers from documents it finds by search, and that search ranks chunks by how similar they are to the question. It does not know who is asking. So whenever documents with different readers share one index, the closest match to a question can be something the person asking was never allowed to see, and the assistant quotes it back.</p> <p>The same leak shows up wherever privacy matters:</p> <ul> <li> <strong>SaaS apps:</strong> someone at one customer asks when their contract
