Every video is a door.
We hand you the key.
Welto puts your language onto video that isn't in it — translated subtitles, a synced bilingual reader and study notes, in Uzbek and 50+ languages.
The best explanation of anything is usually in a language you don't speak.
The lecture that would finally make the topic click, the talk everyone cites, the tutorial that actually goes deep — most of it is in English. If English isn't your first language, you rewatch at 0.75x, guess at half of it, and give up on the rest. Auto-captions are either wrong or missing, and there's nobody to ask.
So we didn't build another summarizer. Summarizing a video you can't follow just hands you a shorter thing you can't follow. Welto puts your language onto the video itself: subtitles you watch it with, the original and your language side by side in step with playback, and a subtitled file you can keep — plus notes and a quiz drawn from what was actually said.
We started with Uzbek, a language most tools ignore, and built out to 50+ more. The goal is simple: no one should be locked out of an idea because of the language it was explained in.
What we care about
The principles behind every decision we make.
Fast by default
You shouldn't have to wait around. Summaries land in seconds, longer jobs run in the background, and you get on with your work.
Every language matters
We build for Uzbek and 50+ other languages as first-class citizens, not as an afterthought bolted on at the end.
Built with care
Premium, considered, and calm. No clutter, no dark patterns, just tools that feel good to use every day.
Your data is yours
We never sell your data or train public models on your content. Your media and transcripts stay private to you.
