Shelf Showdown
Clean
Settle your to-be-read pile in a bracket. Paste the books with their back-cover blurbs, say what you are craving and which tropes are hard nos: a free shelf, trope prescan and seeded bracket in your browser, a blurb read that tags every trope with a quote and estimates heat and darkness, and a position-swapped referee for close matchups. Built on @haowjy/writing-principles and @shipshitdev/advanced-evaluation.
