TL;DR
- Exa now offers Zero Data Retention (ZDR) for its search, answer, and deep research products.
- ZDR means user query data is never stored, adhering to the highest data privacy standards.
- Most search providers cannot offer ZDR because they crawl Google, which trains on user queries.
- Exa developed its own independent search engine over four years, allowing for true ZDR.
- The /answer endpoint provides AI summaries, and the /research endpoint offers deep research reports with ZDR.
- This enhances data privacy for sensitive research topics.
