Plans & Pricing

YourNovel.app offers affordable AI book writing plans starting from €19/month — a fraction of the €5,000–50,000+ cost of a human ghostwriter.

Author Assistant — Free AI Writing Tools for Authors

Already writing your own book? The Author Assistant is a free AI companion that helps you structure, brainstorm, and polish your manuscript. No registration required — start instantly.

Inspector IA — 5 AI Tools in the Editor

YourNovel.app includes an integrated AI Inspector panel with 5 tools accessible directly from the writing editor:

Draft Import — Bring Your Existing Manuscript

Already have a manuscript? Upload your .docx or .txt file and YourNovel.app will automatically analyze it, classify the project type, and populate the Story Bible with characters, locations, and plot points.

Unified Plans — Everything Included

YourNovel.app vs Sudowrite

Sudowrite is great for short fiction in English, but limited to ~30,000 words and requires manual scene-by-scene writing. YourNovel.app generates complete 100,000+ word books autonomously with Auto-Pilot, supports 6 languages, and includes academic citations — features Sudowrite doesn't offer.

YourNovel.app vs ChatGPT for Book Writing

ChatGPT forgets your characters after a few messages and is limited to ~4,000 words per session. YourNovel.app uses Holistic Memory to retain your entire manuscript context across 100,000+ words, with Story Bible and Auto-Pilot mode for fully autonomous book generation.

YourNovel.app vs NovelCrafter

NovelCrafter offers flexibility with AI model selection but requires significant manual context management through its Codex — every character, location, and plot detail must be entered by hand. YourNovel.app's Story Bible is generated automatically as you write or import your manuscript. Additionally, NovelCrafter uses a BYOK (Bring Your Own Key) model where you pay the software ($4-20/mo) plus separate AI API costs ($15-50+/mo), making real costs unpredictable. YourNovel.app offers one predictable price per book with no hidden API fees.

AI Ghostwriter Service — Complete Books Written For You

Looking for an AI ghostwriting service? YourNovel.app functions as a fully autonomous AI ghostwriter. Define your book concept — title, genre, characters, plot outline — and receive a complete, publication-ready manuscript of 100,000+ words. At €19-89/month instead of €5,000-50,000+ for a human ghostwriter, it's the most affordable professional ghostwriting alternative available. Many professional ghostwriters and agencies use YourNovel.app to scale their own production.
