Hey hunters. As a longtime nonfiction publisher—someone who’s lived and breathed the world of Amazon KDP and other self-publishing platforms—my book sales have always funded my ability to explore new creative ventures. Over the years, those royalties gave me the freedom to try new things, including building apps. This is the AI-powered writing tool I dreamed of having when I was putting out my own books. I’m excited to finally share it with all of you today. ❌ The Problem ❌ Let’s be honest, most existing AI writing tools fall short for serious nonfiction creators: 👉 They struggle to produce truly long-form content (30,000+ words is a pipe dream) 👉 They don’t let you bring your own research materials to the table 👉 They fail to match or maintain a unique writing style (mine has been honed over years of publishing) 👉 They don’t do meaningful extra research to enrich the narrative 👉 Their output can feel like a jumbled mishmash of text rather than a cohesive manuscript ✅ The Solution ✅ I built Youbooks to solve all these problems—problems I personally faced: 1️⃣ Upload Your Sources: Bring in your own research materials, transcripts, notes, or articles to ground your book in real data. 2️⃣ Define Your Voice: Provide samples of your writing, so the AI can capture your style and tone—no more generic “AI voice.” 3️⃣ Multi-AI Collaboration: Let multiple AI models (Claude, ChatGPT, Llama, and others) contribute their strengths, argue with each other, and refine the final product. 4️⃣ Complete Long-Form Content: Produce a polished, cohesive book up to 300,000 words—far beyond the capabilities of standard AI tools. 🧐 Key Features 🧐 ✨ Multi-LLM System: Different AI models team up to improve the narrative flow and quality. ✨ Source Integration: Upload reference materials so your book is informed, accurate, and authoritative. ✨ Voice Customization: Maintain your distinct writing style through voice-guided input. ✨ Internet Research: Enable AI-powered web research for up-to-date insights and added depth. ✨ Narrative Coherence: A dedicated coherence module ensures your chapters flow logically and stay on-topic. 📈 Use Cases 📈 👉 Subject Matter Experts: Quickly transform your expertise into a comprehensive, well-structured book. 👉 Non-Fiction Authors & Niche Publishers: Scale your writing output without losing your unique voice. 👉 Thought Leaders: Turn your ideas into long-form content that resonates. 👉 YouTubers & Content Creators: Convert your video content into authoritative books. 👉 Lead Generation: Rapidly produce valuable ebooks for your sales funnel—no more waiting months. 👉 News Publishers: Generate in-depth coverage of trending topics the same day they break. 🎁 Launch Special 🎁 To celebrate our Product Hunt launch, the first 200 users who apply code HUNTHUNT get 100,000 free credits!
