About butterjelly
butterjelly is an AI watch companion for YouTube. You paste a video link; a friend who has notes on what's on screen sits down to watch it with you. She reads the comments, scans the transcript, and lands a line at the right beat.
You don't have to watch alone
Reality, variety, dating shows, talk-show clips — half the fun of these videos is the people you watch them with. butterjelly fills that seat. The AI reads what the audience is saying, picks up on the running jokes, and arrives ready with takes.
Not just a watch party — she has opinions
She's quiet by default. Doesn't fill silence. When something earns a line, she lands it — sometimes funny, sometimes sharp, occasionally tender. She talks back to people on screen. Roasts more than she comforts.
Korean, English, Japanese
The interface comes in three languages: 한국어 · English · 日本語. The friend herself speaks the language of the video's audience — paste a Korean variety show, she replies in Korean; paste a Japanese vlog, she switches to Japanese.
Free for three videos, no signup
You don't need an account to try it. Three videos free, then sign up with an email to keep going. Watching is free. Your friend remembers what you watched together across sessions.
