Derivation Chain

Step 1 Emergence of self-hosted course Platforms

Step 2 Desire among retirees in their 50s to create courses based on career expertise

→

Step 3 The course content production process itself being a technical barrier

Problem

Retirees in their 50s want to turn 30 years of expertise into online courses, but video recording, editing, subtitles, and thumbnail creation are technical barriers. Premiere Pro has a steep learning curve, and outsourcing YouTube editing costs 100,000-300,000 KRW (~$75-$225) per video. Most end up giving up because 'they have great content but can't produce it.' They want to screen-record while explaining over PPT slides but don't know where to start.

Solution

Upload a PPT file on the web and record narration with a microphone — the tool auto-syncs audio to slide transitions, generates subtitles automatically, and converts everything into a lecture video (MP4). It also handles automatic chapter splitting, thumbnail generation, and format conversion for Class101 and Udemy upload specifications — all in one stop.

Target: Ages 50-62, retired or approaching retirement, able to create PPT presentations, no video editing experience, wanting to launch expert-domain courses

Revenue Model: 2 free lecture video conversions per month; unlimited conversions + subtitles + thumbnails for 9,900 KRW/month (~$7.40/month). B2B license for corporate training teams
