Not AI that writes for you. BlurbBio exists to give serious fiction authors the tools to understand, analyse, and strengthen their own manuscripts.
“60,000 words in. Two different characters. Same backstory. Chapters 3 and 21. Nobody catches that until a reader does — and by then it's too late. I needed software that understood my story. Nothing did. So I built it.”

Founded 2025
Fiction authors have a problem that no existing tool solves well. Grammarly checks your grammar. Scrivener organises your files. Sudowrite generates prose. But none of them actually understand your story — the characters, relationships, timeline, arcs, and canon facts that make a novel a novel.
When you're 80,000 words into a manuscript, you don't need something to write the next sentence for you. You need something that knows your world well enough to tell you when something breaks it. When a character knows something they shouldn't yet. When your timeline contradicts itself. When a voice drifts.
BlurbBio is a Story Bible-aware writing platform. Everything — the AI Copilot, conflict scanner, dialogue analysis, plot outliner — works from a living map of your manuscript. It's the writing tool that reads what you've written before it says anything about it.
Four principles that shape every feature we build.
We never generate prose for you. BlurbBio analyses, diagnoses, and suggests — but every word on the page stays yours.
Story continuity, character arcs, timeline conflicts, POV consistency — problems only fiction writers face. We're not a grammar tool with a coat of paint.
AI won't make you a better writer. Deliberate practice will. AI can free you from the busywork so you can focus on craft.
Every feature is built with one question: does this help the author write a better book? Not a faster one. Not a more "optimised" one.
The roadmap in plain terms
Characters, locations, items, factions, timeline, relationships, arcs, lore — one living document that knows your entire world.
Rewrites, diagnostics, brainstorming, voice consistency — all context-aware from your Story Bible. 7 brainstorm modes, not one generic chatbot.
Comp title analysis, reader experience simulation, query letter drafting, revision tracking. Tools for the full author journey, not just the draft.
You're writing a novel — not a short story, not a blog post. You need tools that understand the complexity of long-form fiction.
Maintaining continuity across 3 books, 300 characters, and 5 years of writing? The Story Bible was built for exactly this problem.
You have a draft. Now you need to understand what's working, what isn't, and where the story breaks. That's where our AI analysis shines.
Start free. No credit card required. Your Story Bible, your Copilot, your novel.
