SubtitleSync: YouTube Timestamp Drift Fixer
Automatically detects and fixes misaligned subtitles in YouTube videos by comparing audio-to-text drift, helping creators fix viewer complaints without re-uploading.
The Problem
YouTube creators often discover that subtitles drift out of sync with audio after publishing (due to encoding issues, audio stretching, or platform processing). Fixing this requires re-uploading the entire video, losing all engagement metrics, comments, and ranking signals. Creators currently have no automated way to detect or fix drift without manual frame-by-frame inspection.
Target Audience
YouTube creators with 10k-1M subscribers who publish regularly in education, tutorials, podcasts, and commentary spaces where subtitles are critical for accessibility and SEO.
Why Now?
Creators are increasingly monetizing through ads and Shorts repurposing, making video re-uploads costly. AI audio-sync tools have matured enough to make this feasible as a micro-SaaS.
What's Missing
YouTube's subtitle system doesn't warn creators of drift, and fixing it manually is tedious. Existing transcription services don't solve the post-publish drift problem that creators actually face.
