Quillica is the AI writing assistant built for novelists. Plot, draft, and polish — with an AI that understands story structure, not just text.
Every tool in Quillica is purpose-built for fiction. The AI 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.
Write a fast first draft, then refine with targeted editing — polish, rewrite, fix said-isms, catch repetition. The way professionals actually work.
Build locations, customs, history, and magic systems. The AI 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.
Export to EPUB, print-ready PDF, or DOCX. Set trim size, margins, headers, and front/back matter — ready for Amazon KDP or IngramSpark.
Generate Amazon descriptions with KDP-ready HTML, back cover blurbs, and taglines. Tailored to your genre, audience, and story.
Quillica guides you through a proven novel-writing workflow, step by step.

Quillica is powered by Anthropic's Claude — one of the most capable AI models available, and particularly strong at creative writing.

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.
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 60 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…"
Yes. No contracts, no cancellation fees. Your subscription renews monthly and you can cancel with one click. If you cancel, you keep access until the end of your billing period, then your account reverts to Free.
Paid plans include generous monthly AI usage designed to comfortably cover daily writing sessions. There are no per-word charges and no hard caps that cut you off mid-sentence. We operate a fair use policy — in practice, the vast majority of writers never come close to the limit. If you do hit it and don’t want to wait for your next billing cycle, you can buy an affordable top-up that gives you extra AI usage and rolls over for 3 months.
Quite a lot. You get full access to the planning tools — synopsis, characters, world-building, chapters, scenes, plot threads, and a full novel editor. You can save up to 3 projects in the cloud and export to DOCX. The Free plan is genuinely useful on its own; the paid tiers add AI-powered generation, analysis, and publishing tools.
