What it is
Lucid Book is a browser-based AI story-play platform built around playable books. You can prepare a story before playing or begin with one character and introduce others as the story develops. Scene controls let you change weather, time, genre, mood, and locations while the narrative unfolds. Character profiles can define roles, personalities, behavior, interests, and relationships. You can build worlds with detailed places and characters, then connect characters to locations through roles. Lucid Book says its AI uses book-scale context to remember events and maintain consistency among characters and story details. Books can be shared by link, published in a community library, or locked against editing. Stories can be played in any language. The service runs in a browser, can be installed as a Progressive Web App, and adapts to PC, tablet, and mobile screens. Lucid Book is labeled beta and currently free. The FAQ says users can start by creating a first playable book. Its Privacy & Cookies Policy page says the policy document could not be loaded.
