What's inside
From outline to hook
Paste your premise or outline and get tagline candidates built on the mechanics that make hooks work: stakes, irony, specificity, and the question a browser cannot leave unanswered.
From your manuscript, per bookWriter & Author
Signed in, the Launch Kit writes ten taglines from your actual manuscript across stakes, irony, character, setting and trope angles, in three formats (cover line, ad headline, A+ header), and saves the one you pick to the book.
Marketing copy, not manuscript prose
Taglines are packaging, not story. This is the one place BlurbBio generates finished text, because a hook on a cover is marketing material; your manuscript remains yours alone.
Feeds blurbs and ads
A strong tagline is the seed of the back-cover blurb, the Amazon A+ headline, and the ad creative. Start here, then expand the winner.

Questions
Frequently asked
Specificity plus an open loop. Weak taglines describe genre furniture; strong ones name the impossible situation this particular protagonist is in and leave the resolution hanging. The generator is built around those mechanics: stakes, irony, and the unanswered question.
