The use case: how Firefox deploys Exa
Firefox uses Exa's search endpoint to retrieve and extract relevant passages from the live web, which it turns into AI-generated answers with inline citations in its Smart Window on desktop and Quick Answers on iOS. It can restrict retrieval to certain domains, control freshness, and add content moderation filters.
In the customer’s words

Exa powers Smart Window on Firefox desktop and Quick Answers on Firefox for iOS. Firefox calls Exa's /search endpoint to retrieve, rank, and extract the most relevant passages from each page, synthesizing a direct answer with inline citations, pulling from the live web rather than the LLM's training data.
