Feature questions
The Pro worldbuilding suite includes the World Bible, the Relationship Web, the Time Weaver, the Lexicon Engine, and the Consistency Sentinel. They share one source of truth and sit right beside the editor.
Yes. The Scene Header Linter checks your sluglines for missing prefixes, absent times of day, wrong dashes, and near-duplicate locations, and the Page Count Estimator turns your word count into an estimated page count broken down by act. Both are part of Pro, and both run on their own page or in a panel beside the editor.
The editor, the exercise library, peer feedback, the Progress Report, publishing, and your notebook are free. The worldbuilding suite, unlimited daily exercises, metrics history, and the writing modes are part of Pro.
Yes. Import reads Word, OpenDocument, PDF, EPUB, Markdown, plain text, HTML, and spreadsheets, and pulls your manuscript, characters, timelines, locations, and lore systems in one pass.
No. The prose metrics are deterministic and based on published readability research, and no language model writes or scores your work. The only AI in the product is OpenAI Moderation, used for safety.
The prose grader is free with no account. Drafting, exercises, the community, and the worldbuilding suite need a free account, and Pro has a 7 day trial with no credit card.
Fiction, nonfiction, poetry, screenwriting, journalism, technical writing, copywriting, and blogging, each with its own calibrated metrics.
