AI YouTube Timestamp Generator (Japanese)
YT-MarkerはYouTube動画のURLからAIがタイムスタンプを自動生成するサービスです。有料プラン申込時にサブスクリプション請求が発生します。
In plain English
YT-Marker, made by a solo builder in Japan, writes YouTube time markers from a video link. You give it the address, and the AI marks where each part of the video begins, so a viewer can jump to each part. Creators pay when they choose a paid plan, and that charge is a subscription, because finding those moments means watching the whole video with a finger on pause. The AI does most of the listening and the marker writing, and taking payment is handled too. The builder still checks quality, helps users, and handles unusual videos, so a person still does a real share.
