TextBuilder is an AI platform that generates complete books from a single topic. According to its website, it produces a title, an outline, chapters with examples and action steps, diagrams, and a cover, then exports the result as a PDF, EPUB or DOCX file. The pricing page also lists ebooks, guides and lead magnets as supported outputs.
The site also mentions an AutoWriter tool for SEO articles that publishes to WordPress, and a Social Boost promotion tool. Customer testimonials describe these as parts of a wider content workflow. The company states that users own what they create and hold full resell rights, which matters for anyone planning to publish or sell the books.
The process starts with a topic. Users define the topic, audience and preferences, and the AI proposes a book title, structures the chapters, sections and key takeaways, and maps each key idea from introduction to conclusion. It then writes every chapter, generates diagrams and illustrations, and designs a cover.
The pricing page puts generation time at about 5 minutes, while the homepage says a finished book is ready in under an hour. Usage is metered in credits, with 1 credit equal to 1 word, and a typical book runs 3,000 to 20,000 words depending on the depth chosen. The finished file exports in one click.
The core feature is end-to-end book generation: outline, chapter text, charts, tables, infographics and AI-made illustrations. Covers and images come from Imagen, Ideogram and Flux, while text can draw on Gemini, Claude, OpenAI, LLaMA and DeepSeek. All of these models are included in the subscription, so no API keys are needed.
Beyond non-fiction, the platform lists fiction genres such as romance, thriller, mystery and fantasy, plus workout programs and recipe books. Books can be written in more than 50 languages and exported as PDF, EPUB or DOCX with Amazon KDP-ready formatting. Users keep full resell rights and 100% of any profit from sales.
