MarkdownPreview.org

👋 Hi Product Hunt! I'm the maker of MarkdownPreview, a teaching-first Markdown editor designed for writers — especially Japanese writers — who want to write better, not just format text. Unlike tools like Notion or traditional Markdown editors, MarkdownPreview focuses on helping you clearly see how your writing can be improved, and why those improvements matter. What makes it different: • ✍️ Improve your Markdown writing through real examples, not tutorials • 🔍 Clear word-level before/after diffs to show what changed • 🧠 Writing quality checks that focus on clarity, tone, and consistency • 📘 Feedback that explains *why* a sentence can be better • 📄 Simple reports to help you review and learn from your writing MarkdownPreview is built for Japanese first, where writing nuance matters a lot, and also supports English, Chinese, French, and Spanish. I originally built this tool to help myself write better with Markdown, and I hope it can be useful for other writers as well — including researchers, editors, and anyone who cares about writing quality. I’d love to hear your feedback, especially from writers and learners. Thanks so much for checking it out! 🙏
