YouTube Timestamp Generator

YouTube Timestamp Generator is a web-based AI chapter maker designed to turn public YouTube videos or authorized local uploads into clean, ready-to-paste YouTube chapters. Positioned as a publishing-focused timestamp generator rather than a generic transcript tool, it helps creators, podcasters, educators, course instructors, and marketers add structured navigation to long-form content. Core features include public link and local draft support, trusted duration and credit accounting, AI topic-change detection, editable chapter lists, and YouTube-specific validation for zero start, minimum chapter count, increasing timestamps, spacing, and clean titles. Users preview a bounded segment, unlock full agentic analysis, then copy for YouTube description, Markdown, or .txt export. The UX emphasizes transparency: preview boundaries, processing state, source validation, and field-level feedback are visible before export. Technically, it avoids exposing provider details or private media in the browser, keeps owner-scoped results, and disables export until chapters pass the same validator used in editing. It is built for creators who want accurate chapters without manual timestamping.
