Lucid Book vs Novelcrafter

Lucid Book is a browser-based AI story-play platform built around playable books. You can prepare a story in advance or begin with one character and add others as the story develops. During play, controls let you alter weather, time, genre, mood, and locations. Character profiles can define roles, personalities, behavior, interests, and relationships, and you can build worlds with detailed locations and connect characters to places through roles. The site says its AI uses book-scale context to retain story details and keep characters and events consistent. Books can be shared by link or published in a community library, and editing can be locked. Stories can be played in any language. Lucid Book adapts to PC, tablet, and mobile screens, and can be installed as a Progressive Web App. It is labeled beta and currently free; the FAQ says users can start by making a first playable book. The Privacy & Cookies Policy page says the policy document could not be loaded, leaving the available privacy information limited.

Novelcrafter is a writing platform for authors across genres, forms, and styles, from beginners to published writers. Its long-form writing tools include a Codex wiki for characters, places, lore, and other story information, with entries automatically tracked and linked. A planning grid arranges acts, chapters, and scenes, while a matrix gives an at-a-glance story view. Authors can import Word, Markdown, or HTML files and export their work, and the platform is mobile compatible for jotting down ideas or reviewing stories. Listed AI options include OpenAI, Anthropic, Google, Meta, Mistral AI, OpenRouter, LM Studio, and Ollama. Hobbyist and higher plans allow authors to bring their own AI key. The service has a 21-day trial but no free plan. Scribe costs $4.00 per month, billed monthly; higher plans add AI with a user's own key, chat, advanced review features, and collaborative writing with team management. The privacy policy says creative content is not used to train AI or machine-learning models, and data may be stored in the EU or US, with the EU primary. The company was founded in 2023 and is based in Hamburg, Germany.
