Doc Babel

AI translator for entire books and large documents

Visit Website
January 26, 2026 Hi!

Hey IH!

I just launched DocBabel. An AI translator for entire books and large documents.

The problem: I needed to translate a 400-page PDF. Every tool had character limits (5k-10k chars). For a full book? Useless. Copy-pasting into ChatGPT for hours wasn't an option either.

The solution: Upload your PDF, EPUB, or text file. Pick a language. Get the whole thing translated. No character limits, no copy-paste hell.

Tech stack: React + Vite frontend, Express backend, Supabase for DB/storage, multiple AI providers (OpenAI, Anthropic, Google) for translation quality.

Monetization: Hobby and Pro plans based on monthly translation limits.

Would love feedback from the community. What features would make this more useful for you?

    Hey πŸ‘‹

    Saw your project β€” looks interesting.

    Quick question: are you open to collaborations or partnerships?

    I have a SaaS product that could be a great fit to promote (commission-based).

    Let me know πŸ‘

    Congrats on the launch, looks solid. How are you currently thinking about acquiring early users and gathering feedback?

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 tool I found had the same problem: character limits. 5,00
