Quillica is the writing assistant built for novelists. Plan, write, and polish — with tools that understand story structure, not just text.
Every tool in Quillica is purpose-built for fiction. It understands your characters, your world, and your voice.
Paste samples of your prose and Quillica learns your writing style — rhythm, vocabulary, sentence structure. Every generated word sounds like you.
Track subplots, foreshadowing, clues, and motifs across your entire novel. Never lose a thread or forget to pay something off.
Draft prose that knows your characters, setting, atmosphere, and POV. Context-aware writing that respects scene boundaries.
Get chapter-by-chapter feedback like working with a real editor. Quillica flags pacing issues, weak dialogue, plot holes, and repetition — then helps you fix each one with guided rewrites.
Build locations, customs, history, and magic systems. Quillica references your world bible when writing scenes set in those places.
Writing a series? Quillica tracks continuity across books — character arcs, unresolved threads, timeline consistency.
Quillica guides you through a proven novel-writing workflow, step by step.
"Most tools treat fiction like a text completion problem. Quillica treats it like storytelling — from first draft to final editorial review."— The Quillica Approach

Quillica is powered by Anthropic's Claude — one of the most capable AI models available, and particularly strong at creative writing. Unlike generic chatbots, Quillica sends rich context about your characters, world, and story structure with every request, so it always writes within your story's reality.
Yes, completely. Everything you write or generate with Quillica is yours. We make no claim to your content whatsoever. Your stories, characters, and worlds belong to you.
Quillica operates on a fair-use policy. Both plans include a generous monthly allowance — more than enough for daily writing sessions. If you're writing consistently, you won't hit the limit. We designed it so you can focus on your novel, not count usage.
Your projects are stored in a secure, encrypted database. We never share your content with third parties, and your writing is never used to train AI models. You can export or delete your data at any time.
ChatGPT is a general-purpose chatbot. Quillica is a complete novel-writing studio with over 40 purpose-built tools. It understands story structure, tracks character arcs, manages subplots, learns your writing voice, and generates prose scene-by-scene with full context — not just "write me a story about…"
