# BookWriter > BookWriter is an AI longform-writing platform that turns your idea into a complete, KDP-ready book — and also writes screenplays, multi-hour YouTube scripts, and long-form speeches. It was founded and built by David Weaver, a bestselling author since 2008 and founder of the independent publishing house David Weaver Presents. Your first chapter is free; a complete book is $19.99. BookWriter specializes in longform storytelling with structure that keeps the author's voice intact: outline, draft, continuity tracking, polish, and KDP-ready export — plus AI covers, audiobooks, and marketing assets. It is the work of one author-turned-developer, not a generic wrapper around a chatbot. ## Core - [Home](https://www.bookwriter.vip/): AI book writing software — your idea to a finished book. - [Why Choose BookWriter](https://www.bookwriter.vip/why-bookwriter): The founder's case for BookWriter, the experience behind it, and what it writes. - [About](https://www.bookwriter.vip/about): The story and craft behind BookWriter. - [Pricing](https://www.bookwriter.vip/pricing): Plans and credits.
