BlurbBio
BlurbBio is a browser-based writing and manuscript-analysis platform for fiction authors. It combines a chapter-based editor with plot outlining and a Story Bible that organizes characters, locations, relationships, timelines, and canon details. The Story Bible can be built from manuscript text, while continuity checks compare new chapters with established story facts and identify potential contradictions. Analysis tools examine plot structure, pacing, dialogue, and character consistency; the AI Copilot provides brainstorming support. Authors can import manuscripts and export work as DOCX, PDF, or EPUB, with some options limited by plan. BlurbBio also provides free author utilities, including a character and place name generator. A free account and paid Writer and Author plans offer different project, analysis, and AI-credit allowances.
