Belin Doc - Translate, edit, and collaborate on docs in one AI workspace

📌 Hey Product Hunters! 👋 I just shipped BelinDoc — a document AI I wish existed when I was translating my dad's 200-page engineering manual last year. 📖 The Story He wrote the whole thing in Portuguese; I needed it in English for work. Google Translate mangled the technical terms, DeepL didn't handle the figures, and every "PDF translator" I tried wanted a subscription, an account, and a sacrifice to the signup gods. Two weeks of copy-paste later I had a half-finished mess. So I built BelinDoc for the next person stuck in that loop. ✨ What it does - 🌍 100+ languages with terminology you can pin per project - 📄 Keeps original layout — tables, figures, footnotes, code blocks - 🪄 Ask-the-doc: rewrite, summarize, extract clauses in plain English - 👥 Live bilingual editor — comment in your language, ship in theirs - 📤 Export to PDF / DOCX / EPUB / side-by-side Markdown 🙌 Your feedback matters This is v0.1 and I'd love to know: - Which document format is the most painful for you right now? - What should "Ask the doc" be able to do that it can't yet? - Any language pair where quality still feels off? Drop a comment, an upvote if it sounds useful, and share the worst-translated document you've ever seen 😅 — Frank
