What Our Users Say
Trusted by knowledge workers, developers, and legal teams worldwide
“We were spending 3 hours per case manually copying text from scanned depositions. MDConvert with AI Vision does it in minutes. The table extraction alone saved our paralegals an entire day per week.”
“I converted my entire library of 40+ coaching books into Markdown and built a custom GPT that references all of them. My clients now get personalized insights pulled from decades of leadership research. Game changer.”
“We tried Pandoc, pdf2md, and three other tools before finding MDConvert. The difference is night and day — especially for PDFs with complex tables and multi-column layouts. Our RAG pipeline accuracy jumped 40% just by switching the document prep step.”
“I manage document conversion for a team of 12 writers. The batch ZIP upload alone saves us hours. And the Markdown output is so clean that our CMS imports it without any manual formatting fixes.”

Answers for knowledge teams converting e-books into AI-friendly knowledge bases.
Can I use this to build a custom GPT from my book library?View answer
Absolutely! Convert your ePub books to markdown, then upload the markdown to ChatGPT when creating a custom GPT. Many coaches and consultants use this workflow to build AI assistants trained on self-help books, business frameworks, and training materials.
Will the converter keep my EPUB table of contents and structure?View answer
Yes. Chapter and section headings become Markdown headings, and we ship a clickable table of contents at the top of your file. This structure is perfect for AI training as it maintains the logical flow of the content.
How large of an ePub file can I convert for AI training?View answer
We support ePub files up to 100MB, which covers even the largest self-help books and comprehensive training manuals. The free plan allows conversions with no file size restrictions.
Is the markdown output optimized for ChatGPT and other LLMs?View answer
Yes. Our conversion process creates clean, structured markdown that is specifically optimized for AI consumption. We preserve semantic structure, remove unnecessary formatting, and ensure the output is token-efficient for LLM training.
Can I convert DRM-protected ePubs?View answer
We can only process DRM-free files. Remove DRM with your provider first, then upload the clean ePub for conversion. Most personal development and business books purchased from major retailers can be de-DRMed for personal AI training use.
What types of books work best for AI coaching assistants?View answer
Self-help books, business frameworks, personal development guides, and training materials convert exceptionally well. Books with clear chapter structures, actionable advice, and proven methodologies make the best training data for AI coaching assistants.
