For the awkward ones
No script to learn, no fortieth take of the same sentence, no hearing your own voice back. You pull a few faces, and the words appear on screen.
Japper writes every word after that.
A song or meme, not your voice
The hook and payoff are on screen, set to a trending song or meme sound. A voice-over is there if you ever want one.
Seconds, not monologues
Each reaction is a short clip without a word in it, tagged by emotion and reused for every video.
Or stay off camera
Invite a co-founder, friend or creator to film the reactions for you. You approve their takes first.
Yes, but only once and without saying a word. A reaction is a few silent seconds of you acting out an emotion. Six takes cover every video Japper makes, and you can invite a co-founder or creator to record theirs instead.
Reactions: short silent clips of you being surprised, shocked, happy, confused, nodding or facepalming. A demo: a screen recording of your product, or your screen filmed with a phone. Frames, the filmed devices a demo is pinned into, come with Japper, or you film your own.
The format Japper makes today: a vertical 1080 by 1920 video at 30 frames a second. Your reaction runs one to ten seconds with the hook on screen, then your product takes over with the payoff. Or it stops after the reaction. A yapper is someone who talks about their thing all the time, and more formats will follow.
The writing: your brand book, topics, hooks, payoffs, captions and the research. The video itself is only your own footage, composed together. No AI faces, voices or lip-sync, ever, and no generation credits burned per second of video.
TikTok, Instagram, Facebook Pages and YouTube Shorts. Everything else you reach by downloading the videos, with the CSV that comes with them.
TikTok requires that you choose the audience, the interaction settings and any commercial disclosure per post. Japper asks for those before the planned time and then posts. Instagram, Facebook and YouTube posts go out on their own.
It starts free: three videos on your own product, no card and no time limit. Sign up with your email address and your first video is ready within ten minutes.
