Hey Product Hunt! 👋 I built Korean Diary AI because I was frustrated waiting 24+ hours on HiNative for feedback on my Korean writing. By the time the correction arrived, I'd already lost the context — and the motivation. So I built something different: write a Korean diary entry, get AI corrections on grammar, vocabulary, and naturalness in under 5 seconds. We just finished a private beta with learners from the US, Malaysia, and Korea. Two beta users liked it enough to upgrade to paid within the first week — that kind of early validation kept us going. If you're learning Korean (or know someone who is), we'd love your feedback. Try it free → https://kdiaryai.com Happy to answer any questions below! 🙏

What's your biggest blocker to writing in your target language daily?

Been a few months since I launched Korean Diary AI here, and I'm still tinkering with it based on what learners actually struggle with.

Curious what this community thinks: what's the #1 thing that stops you from writing in your target language every day? For me building this, it was the feedback loop if a correction takes 24 hours, the motivation (and context) is gone by the time it arrives. That's why I built this around getting corrections in seconds instead.
