Outline
Describe a subject and Mentible drafts a real table of contents — parts, chapters, topics. You set the shape and scope until it is exactly the book you mean.
AI Book Authoring For Self-Learners
Mentible
Author Yourself.
The content is the commodity — every model already has it. Mentible is where you shape it: outline the book you want, set its scope, and compile a real EPUB or PDF that's exactly what you decided it should be — yours to keep, read offline, and share.

How it works
From a spark of curiosity to a finished book
Three deliberate steps — that's the whole product.
Generate
Fill it in topic by topic. Each chapter comes back scoped to the level, depth and boundaries you set — with math, diagrams and worked examples. The content is cheap; your spec is the point.
Compile
Press publish and Mentible compiles a polished EPUB3 / PDF with a real cover and theme. The finished book is yours — read it offline, keep it, share it.
Why Mentible
You hold the controls
The model is the commodity. The shaping — scope, boundaries, structure — is where the value is.
Books, not chat
No endless chatbot, no catalogue of canned courses. One focused loop: outline → generate → compile a real artifact.
Provider-agnostic
Works across Anthropic and the OpenAI-compatible providers — OpenAI, DeepSeek, Qwen and more. The model is the commodity; the scoping is the craft.
Your keys, your way
A managed subscription so you just start writing, or bring your own API key and pay the provider directly. Hybrid by design.
Real artifacts
Every book compiles to EPUB3 and PDF with covers, a theme system and a draft → published lifecycle. The book is the product.
Beautiful by default
KaTeX math, Mermaid diagrams, tables and accessible typesetting render automatically — no formatting busywork.
Built for adults
Self-paced learning for working professionals and the endlessly curious. Go deep, on your own terms — no fluff, no school.

Transparency
Content authenticity, stated plainly
Mentible is AI-powered, and we say so up front. When you generate a book, an LLM writes the draft under the scope and boundaries you set — that's the point, not something we hide. Here's how we keep it honest and verifiable.
Provenance that travels
Every export carries a Content Trust Manifest — which model produced it, when it was generated, and the settings used. That provenance stays with the file when you export or share it: your proof the material is what it claims to be — disclosed, AI-assisted educational content.
The honest picture on "AI watermarks"
You may have heard that AI models secretly watermark their text. For the models Mentible uses today, mostly not: major text models — including Claude — don't embed a hidden, detectable watermark in the words they generate. The notable exception is Google Gemini, which marks its text output (SynthID), and even that signal can fade when text is edited or recompiled, as it is when Mentible builds your EPUB or PDF. Where a provider does mark its output, we tell you at the point you choose the model.
AI-detectors & your institution
Plagiarism and AI-detection tools may flag AI-assisted material. With Mentible that isn't something to hide from — your Content Trust Manifest already discloses the model, the date, and how the content was made. Authenticity here means honest provenance, not pretending a human wrote it.
Your choice, disclosed
You pick the model; we tell you what that choice means — including any provider marking practices — before you generate. Providers handle this differently, and that difference is shown where you select.
