Hi Product Hunt, Tristan here.

I build small apps, and one of them, VibeThoughts, had no marketing at all. Short videos were the obvious channel, but a talking-head video means a script, retakes and doing it all again next week.

So I built Japper. You film a few silent reactions and one screen recording, once. Japper writes a brand book from one line about your product, plans a topic and hook for every day you post, composes the videos from your own footage and posts them. Three days after each post it reads the views back, and what performed best shapes the next plan.

AI only does the writing. The video is your real footage, with no AI faces or voices.

I have been running it on VibeThoughts for 20 days: 14 reactions filmed once, 17 videos and 15.7K views across TikTok, Instagram and YouTube, all from zero. That is views so far, not revenue.

One honest caveat: TikTok requires you to confirm each post yourself. Instagram, Facebook and YouTube go out on their own.

Your first three videos are free, no credit card needed.

I would love your feedback on two things. Would you film the reactions yourself, or send the invite link to someone else? And looking at the gallery, would you post a video like this for your own product, and if not, why not?
