Hey Product Hunt! 👋 I’m Ruon.

I'm incredibly excited to share Hapio AI with you today - a presentation practice platform that's been my passion project as a solo Japanese developer!

🎯 Why I built this?

As someone who's struggled with presentations throughout my career, I noticed a huge gap: we practice speeches in our heads, but rarely get objective feedback on our actual delivery. Whether it's a crucial business pitch, academic presentation, or even practicing for a foreign language class, most of us wing it and hope for the best.

I wanted to create something that gives you the honest, constructive feedback you'd get from a presentation coach - but available 24/7, without judgment, and tailored to your specific situation.

🚀 What makes Hapio AI different?

✅ Situational Intelligence: Unlike generic feedback tools, Hapio AI evaluates your presentation based on the specific context - whether you're pitching to investors, presenting to students, or giving a sales demo

✅ Multi-dimensional Analysis: We don't just listen to your words. Hapio AI analyzes your speech transcription, facial expressions, slide content, timing, and how everything works together

✅ 5-Perspective Evaluation System:

Content Accuracy

Language & Wording

Situation Appropriateness

Facial Expression

Structure & Logic

✅ Privacy-First: Your audio/video never leaves your device. We only process transcriptions and facial expression data points

✅ Language Learning Integration: Perfect for practicing presentations in foreign languages with vocabulary and expression suggestions

🎯 Who it's for:

Business professionals preparing for pitches, meetings, and project presentations

Students practicing academic presentations

Anyone learning a foreign language who needs to present

Really, anyone who wants to communicate more effectively!

The name "Hapio" comes from the Japanese word "happyou" (発表) meaning "presentation." As a solo developer, I believe that by helping people improve their presentation skills, we can make the world shine a little brighter in this AI-driven era where human communication skills matter more than ever.

🙏 My ask:

As a solo developer from Japan, I'd love your feedback! Try it out, tell me what's missing. Your insights will directly shape where Hapio AI goes next.

⚠️ A heads up: Since I'm based in Japan, please bear with me if responses are delayed due to timezone differences. Also, as a one-person operation, I'm keeping a close eye on database performance - I've set up read replicas to handle traffic, but please let me know if you experience any slowdowns.

Thanks for checking us out - let's make presentations less scary and more impactful together!
