About NexClip AI
The Story
I've spent 25+ years editing video — broadcast, corporate, documentary. Thousands of hours of footage, trimmed down to minutes that matter.
The hardest part was never the cutting. It was the finding. Scrubbing through a 60-minute interview to locate the 3 minutes where the CEO says something real. Watching an entire webinar just to pull the pricing discussion.
Every AI clipping tool I tried made the same assumption: the AI should decide what's important. But "interesting" and "relevant" aren't the same thing. So I built something different — a native macOS app that asks you what matters, instead of guessing. Read why I went native macOS →
What is NexClip AI
NexClip AI is a native macOS app that introduces Topic-Based Editing — a patent-pending approach where AI extracts every topic from your video and lets you choose which ones to clip.
Your video files stay on your Mac. Only audio is sent for transcription, then immediately deleted. It works with both Japanese and English, with language-specific NLP processing. And it exports to Final Cut Pro, DaVinci Resolve, and Adobe Premiere Pro — so it fits into your existing workflow.
The Founder
Kiyoshi Nagahama
Founder & Developer, NexClip AI
25+ years in video production across broadcast, corporate, and documentary. Now a solo founder building NexClip AI — combining decades of industry experience with AI to solve a problem I've lived with my entire career.
NexClip AI is built with Swift, SwiftUI, and Rust (via UniFFI) for the macOS app, with Next.js on the backend. Every line of code is written by one person — from the Rust NLP engine to the Swift video pipeline to the web API.
