During a ten list hunt I came across author Kathy Carmichael's Pitch Generator, which generates a simple novel pitch from information you fill in the blanks.
It can also help out outline a broader concept, like the core conflict of a novel series. Here's a general example (I changed some of the generated wording to encompass a series concept:)
StarDoc is a 1,000,000+ word science fiction novel series set in the far future on various alien worlds. Dr. Cherijo Grey Veil is a bioengineered cardio-thoracic surgeon who believes in doing no harm, and in fighting for freedom and equality for all life. She wants to preserve peace and life because it is essential to the survival of all species. She is prevented from attaining this goal because a malignant crystal bent on destroying all life has invaded most of the inhabited planets in the galaxy.
(Now I have to go get over the fact it took me more than a million words to tell Cherijo's story . . . )
