About WatchMeSenpai
Last updated: February 2026
What is WatchMeSenpai?
WatchMeSenpai is a free web application that allows you to watch YouTube videos with your own custom subtitles. Whether you're learning a new language, need accessibility features, or want to add subtitles to videos that don't have them, WatchMeSenpai has you covered.
Why We Built This
We noticed that many YouTube videos lack subtitles, have poor-quality auto-generated captions, or don't have subtitles in the language you need. WatchMeSenpai solves this by letting you bring your own subtitles to any YouTube video.
Our goal is to make video content more accessible to everyone, regardless of hearing ability or language proficiency.
Key Features
- Multiple Format Support: Upload subtitles in SRT, VTT, or ASS/SSA format
- Easy Time Sync: Adjust subtitle timing with precise offset controls and our unique Sync Point feature
- Customizable Display: Change font size, colors, background, and positioning
- Timeline Editor: View and navigate subtitles on an interactive timeline
- URL Loading: Load subtitles directly from a URL - no download needed
- Dark Mode: Easy on the eyes with full dark mode support
Privacy First
WatchMeSenpai is designed with privacy in mind. All subtitle processing happens locally in your browser - we don't upload or store your subtitle files on any server. Your viewing habits and subtitle choices remain completely private.
