The whole of your library, on call.

A private research library over the books you own — faster, more thorough, and more accurate than reading them one at a time.

• Your closed corpus

  Every answer is drawn only from the books you own — nothing from the open web.

• Cited, and verifiable

  Each claim links to the exact passage it came from, so you can check the source.

• An expert that asks back

  Deep research, document critique, and a librarian that questions you to sharpen the answer.
