The fine print, lightly

  • Fetched live

    Article text is pulled from the source when you need it. We don't store article bodies in our database. Publisher terms may still apply.

  • Private-by-default AI

    Your question, relevant excerpts, and a little recent chat go to OpenRouter with Zero Data Retention. They may keep metadata like model, timing, and token counts.

  • Light records

    Saved papers store identifiers, not the article. Chat messages stay until you delete them. Answers can be wrong, and they're not medical advice.

  • Independent

    Expansive Mind isn't affiliated with or endorsed by NIH, NCBI, Springer Nature, Google Scholar, SerpApi, OpenRouter, or the article publishers.
