Miguel Santaolalla

I wanted to translate a 400-page PDF book. My options? Copy-paste chunks into ChatGPT / Google Translate for hours, or pay thousands for a human translator.

Every translation tool I found had the same problem: character limits. 5,000 characters here, 10,000 there. For a full book? Useless.

So I built what I needed: upload a book, get it translated. The whole thing. Not page by page, not chapter by chapter — the entire document.

DocBabel handles:
- Full books (PDF, EPUB)
- Long research papers
- Technical documentation
- Any large text file

The AI maintains context across hundreds of pages, keeps terminology consistent, and preserves the author's writing style.

If you've ever needed to translate something longer than a few paragraphs, I'd love to hear about your experience and what features would help you most!
