Plans & Pricing

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.

5 Fatal Mistakes When Writing a Book with AI (and How to Avoid Them)

Artificial intelligence has democratized book writing. Today, anyone with an idea can generate a manuscript. But democratizing doesn't mean simplifying: most AI-written books are mediocre because their authors make avoidable mistakes.

The "good enough" trap when writing with AI

Artificial intelligence has democratized book writing. Today, anyone with an idea can generate a manuscript. But democratizing doesn't mean simplifying: most AI-written books are mediocre because their authors make avoidable mistakes.

After analyzing hundreds of AI-generated manuscripts, we've identified the 5 most destructive mistakes — and their solutions.

Mistake #1: Using a generic chatbot to write an entire book

This is the most common and most damaging mistake. Millions of people open ChatGPT, Claude, or Gemini and say: *"Write me a 300-page fantasy novel."*

The result is predictable: the first chapter is decent, the second loses steam, and by chapter five, the AI has forgotten the main characters' names. Why? Because chatbots aren't designed for long-form writing. Their context window is limited and they have no persistent memory mechanisms.

Solution: Use tools specialized in book writing, like YourNovel.app, which incorporate Holistic Memory systems specifically designed to maintain coherence in 100,000+ word manuscripts.

Mistake #2: Not defining a structure before writing

Many authors start generating text without a plan. They let the AI improvise chapter after chapter, and the result is a directionless book with abandoned subplots and erratic pacing.

A professional book — fiction or non-fiction — needs a clear architecture before writing the first word: acts, chapters, scenes (in fiction) or thematic sections (in non-fiction), each with defined narrative objectives.

Solution: Generate a complete holistic structure first. In YourNovel.app, the AI creates the entire book's structure (chapters, scenes, objectives) before writing a single paragraph, ensuring every piece fits the global puzzle.

Mistake #3: Publishing the first draft without revision

AI's speed is seductive. You can have 100,000 words in a few hours. But a first draft — human or AI — is never ready to publish.

AI drafts typically have problems with:

  • Phrase and structure repetition (AI has favorite patterns)
  • Inconsistent tone between chapters
  • Abrupt transitions between scenes or sections
  • Limited vocabulary in long passages

Solution: Use AI Audit tools that analyze the entire manuscript looking for inconsistencies, repetitions, and style issues. YourNovel.app includes a specialized AI editor that reviews each section in the context of the entire book, not in isolation.

Mistake #4: Ignoring character and plot coherence

In novels, this mistake manifests notoriously: a character changes personality between chapters, a secret revealed in chapter 3 becomes secret again in chapter 12, or dates and ages don't add up.

In non-fiction, the equivalent is contradicting yourself: stating something in chapter 2 and the opposite in chapter 8, or repeating the same information in three different places.

Solution: An automatic Story Bible that records all story elements (characters, locations, world rules, key events) and injects them as context every time the AI writes a new section. This is exactly the technology behind Holistic Memory.

Mistake #5: Poor manuscript formatting for publication

You have a 300-page book and want to publish it on Amazon KDP. You copy the text, paste it into Word, and upload it. The result: a book without professional formatting, inconsistent typography, no page breaks between chapters, and no navigable table of contents.

Kindle readers spot a poorly formatted book within the first 30 seconds and request a refund.

Solution: Export your manuscript in professional DOCX with editorial formatting: Times New Roman 12pt, justified text, first-line indent, page breaks between chapters, and structured headings for Kindle's automatic table of contents. YourNovel.app generates this format automatically.

Conclusion: AI is the tool, not the author

Writing a good book with AI requires the same creative decisions as writing without it: define a vision, plan the structure, review the result, and format professionally. The difference is that, with the right tool, you can do it in hours instead of months.

The key is choosing a platform designed for writing books — not a chatbot designed for answering questions.
