Hi everyone! 
We’re a small startup team that’s been deep in the AI video space for a while now — experimenting, failing, learning, and building. Today, we’re thrilled to share the result of our latest work: AddSubtitle .
AddSubtitle is a web-based AI video editor designed to help creators translate and localize their videos at scale — without needing complex tools or large teams. It’s built to solve the real pain points we’ve heard from educators, marketers, YouTubers, and localization teams.
Here’s what AddSubtitle can help you do:
- Perfect Subtitles — Generate, customize, and edit high-accuracy multilingual closed captions with fonts that fit every language
- Speak Globally — Translate videos into 100+ languages with cultural nuance preserved
- Sound Your Way — Clone any voice or choose from our diverse AI voice collection
- Look Authentic — Auto-align lip movement and facial expressions with your translated or rewritten content
- Edit with Words — Just update your script, and we’ll regenerate the voiceover, lip sync, and subtitles instantly
It’s all browser-based, no software needed. Just upload or paste a YouTube link and start editing.
We’d love for you to try it out at https://addsubtitle.ai
