Scrivibe — Complete Guide

Overview

Scrivibe is an AI-powered eBook generation platform that lets anyone — from first-time writers to AI agents — produce professional, multi-chapter eBooks in minutes. It combines Anthropic's Claude language models with a robust EPUB pipeline, a token-based economy, and full developer integrations.

Quick Start

You can create your first eBook in under 5 minutes without registering. Here is the full flow:

• 1

  Open the app

  Visit scrivibe.com. You automatically receive a welcome token balance as a guest.

• 2

  Fill in your book details

  Enter a title, choose your genre and subject theme, write a short premise, set the tone and target audience. Pick the number of chapters (1–50).

• 3

  Generate the AI framework

  Click "Generate AI Framework". Claude creates chapter titles, summaries and a narrative continuity plan. A cover proposal is generated automatically.

• 4

  Generate chapters

  Click "Generate All Chapters" to fill in full prose, or expand chapters individually. Real-time progress is shown via Server-Sent Events.

• 5

  Download your eBook

  Once complete, click the Download button to get your EPUB. You can also export as PDF, DOCX, or TXT from My Books.

• 6

  (Optional) Register to save & earn

  Register for free to keep your books, earn a signup bonus in tokens, and unlock the First Book Guide reward.

Guest vs Registered Users

Token Economy

Scrivibe uses an internal token currency for every AI action. Tokens are consumed when content is generated; they are never refunded after successful generation starts.

How tokens are assigned

Buying Tokens

Registered users can purchase additional token packs through Stripe Checkout. Go to Profile → Buy Tokens or navigate to /tokens/buy.

• 1

  Choose a pack

  Select the token pack that fits your project size. Larger packs have a lower cost-per-token.

• 2

  Stripe Checkout

  You are redirected to a Stripe-hosted payment page. Card details never touch Scrivibe servers.

• 3

  Instant credit

  On successful payment, tokens are credited to your balance immediately via a Stripe webhook.

Rewards & Bonuses

Registered users can earn free tokens through in-app activities.

Book Generation

The core feature of Scrivibe. The generation pipeline runs in two phases: framework (outline + chapter plan) and content (full prose per chapter).

Book Configuration Fields

Generation Pipeline

1. Web Research — DuckDuckGo + trafilatura scrape relevant sources automatically for non-fiction genres.
2. Framework Generation — Claude creates chapter titles, summaries, character bibles and narrative continuity data.
3. Cover Proposal — OpenAI gpt-image-2 generates a cover image from the book premise immediately after framework.
4. Chapter Prose — Each chapter is generated in sequence using the narrative continuity system to ensure smooth transitions.
5. EPUB Assembly — ebooklib compiles all chapters, metadata, cover image, and optional front/back matter into a valid EPUB 3 file.

Anti-Hallucination & Continuity

The Narrative Continuity System stores chapter context (character states, plot threads, established facts) as each chapter is generated. This context is injected into subsequent chapter prompts, preventing contradictions and ensuring consistent storytelling across the entire book.

Circuit Breaker & Stuck Tasks

A circuit breaker pattern monitors generation health. Tasks that stop responding are automatically detected and cleaned up. Truncated chapters from interrupted sessions are repaired on next startup.

Cover Generation

Scrivibe automatically generates a cover image after the AI framework is built. You can also request a new cover manually at any time from the book view.

• Uses OpenAI gpt-image-2 model.
• The cover prompt is derived from the book title, genre and premise.
• Cost: a number of tokens per generation.
• The cover is embedded directly in the EPUB file.
• A right-click context menu allows saving or regenerating the cover from the book view.

Export Formats

Every completed book can be exported in multiple formats from the My Books dashboard or the book view.

My Books Dashboard

The My Books page (/my-books) is the central hub for managing all your generated content.

• View all books with status: draft, generating, complete.
• Download any completed book in EPUB, PDF, DOCX or TXT.
• Open a paginated reader preview directly in the browser.
• Delete books you no longer need.
• Add a book to the Amazon Bookshelf listing (registered users).
• Generate or re-generate the cover art for any book.
• Generate a video trailer for any completed book.
• Share books via Web Share API, email, or shareable link.

Sharing & Bookshelf

Shareable Download Links

Registered users can generate tokenized 72-hour download links that let anyone download the EPUB without being logged in. These links are single-use and expire automatically.

Web Share API

On supported devices (iOS Safari, Android Chrome), the Share modal triggers the native OS share sheet for easy sharing to WhatsApp, Twitter, etc.

Amazon Bookshelf

The Bookshelf feature lets you submit your completed book to the public Amazon Bookshelf — 14 regional stores (US, UK, DE, FR, ES, IT, NL, JP, BR, CA, MX, AU, IN, SE). The system validates ASINs and generates affiliate URLs automatically.

Video Book Trailer

Scrivibe generates a 1080×1920 portrait MP4 video trailer for completed books. Two quality tiers are available.

How to generate a trailer

1. Open a completed book in My Books.
2. Click "Generate Trailer".
3. Choose Standard or Cinematic (requires your Runway API key for Cinematic).
4. Optionally customize voice, tagline, and music mood.
5. Click "Generate". Token cost is deducted immediately.
6. The trailer generates asynchronously. A progress indicator is shown. Download the MP4 when ready.

Multilingual Support

Scrivibe supports 15 languages for both the UI and book generation. The interface automatically detects browser language preferences.

Language-specific landing pages are available at /<lang_code>/ (e.g. /es/, /fr/). Books generated in a specific language will use that language's writing conventions and narrative style.

B2A REST API

The Book-to-Agent API (/v1/) is a REST interface for programmatic eBook generation. It is designed for AI agents, automation pipelines, and developer integrations.

MCP Server

Scrivibe implements the Model Context Protocol (MCP) — a standard for AI agents to use external tools natively. This means Claude, GPT, and other MCP-compatible agents can use Scrivibe without a custom integration.

MCP Endpoint

POST https://www.scrivibe.com/mcp

The endpoint accepts JSON-RPC 2.0 calls. The following tools are exposed:

Payment Gate

When an AI agent calls generate_ebook without an API key, the server returns a Stripe Checkout URL embedded in the JSON-RPC response. The user must complete payment ($0.45 per chapter) before the job is enqueued. This enables monetized MCP usage without pre-registration.

Example MCP call (JSON-RPC)

{
  "jsonrpc": "2.0",
  "method": "tools/call",
  "id": 1,
  "params": {
    "name": "generate_ebook",
    "arguments": {
      "title": "The Future of AI",
      "genre": "nonfiction",
      "chapter_count": 5,
      "description": "An accessible guide to how AI is reshaping every industry."
    }
  }
}

Supported Genres

Use these IDs in the genre field of book creation requests. For a live list with all subject themes, call GET /v1/genres.

Frequently Asked Questions

Can I edit the generated chapters?

You can preview each chapter and regenerate it as many times as you like — adjusting tone, length, or focus via the book settings before each run. If you need to make text-level changes, download the chapter (EPUB, PDF, DOCX, or TXT) and edit it in your preferred writing tool.

What happens if generation is interrupted mid-way?

The system uses progressive saving — each chapter is written to the database as it completes. If generation is interrupted, you will retain all chapters generated up to that point. The startup repair system also automatically fixes truncated chapters on the next server start.

Can I generate books in languages other than English?

Yes. Set the language field to any supported ISO 639-1 code. Claude will write prose, chapter titles, and meta content in the specified language.

My tokens were deducted but the book failed. Will I get them back?

Tokens are consumed per chapter as they are generated — they are not pre-deducted in a lump. If a trailer or cover generation fails entirely before completing, the system issues an automatic refund to your balance.

What AI model powers Scrivibe?

Book generation uses Anthropic Claude Sonnet 4.5 for standard generation and Claude Opus 4.6 for premium (when configured). Cover generation uses OpenAI gpt-image-2. Cinematic trailer animation uses Runway Gen-4 Turbo.

How do I get a B2A API key?

Subscribe on RapidAPI. A free tier is available — no Scrivibe account required. Once subscribed, your X-RapidAPI-Key is shown on the RapidAPI dashboard and auto-injected into every code snippet. The B2A API does not issue direct API keys.

Is there a chapter limit?

The current hard limit is 50 chapters per book (both web UI and API). There is no minimum; a 1-chapter book (short story or guide) is valid.

Can I use the MCP server with Claude Desktop?

Yes. Point your Claude Desktop MCP config to https://www.scrivibe.com/mcp. Full setup instructions are at /mcp-guide.

Are there rate limits?

Yes. The B2A API is rate-limited by RapidAPI according to your subscription plan. The web app and public endpoints are rate-limited by IP. If you receive a 429 Too Many Requests response on the API, upgrade your RapidAPI plan or wait for your quota window to reset.
