Bulin 47 AI Video Generator
Turn one photo into a 23-second Bulin 47 freestyle video with the original sound.
What is Bulin 47 AI Video Generator?
Bulin 47 AI Video Generator is a web tool that turns a single photo into a 23-second vertical MP4 of a Bulin 47 freestyle video, keeping the original sound. The person in your photo is placed into the prepared freestyle as the lead performer, using the original performance as a reference for gestures and camera movement. No prompts are needed.
The tool is aimed at people who want a personal or playful AI remix for their social feed or group chat, or who want to make a version featuring a friend. Custom mode also lets you replace up to four people in the crowd with photos of friends, while Original mode keeps the original street crowd. Standard (480p) and HD (720p) quality options are available.
Uploads are limited to clear, single-person adult photos up to 10 MB, and the site states that photos are only sent for AI processing when you generate. Credits are used per video, and failed renders return credits. The site describes itself as an independent tool, not affiliated with Bulin 47 or Kevin Wai, and notes that results are AI-generated adaptations rather than real performances. Exact lip sync and details are not guaranteed.

we have product pages... 42,000 founders have created products they share often share their revenue that's like stripe verified... we're just we're choosing not to monetize it right now because we don't have to and it it is useful to the community but we have that switch to flip on we don't touch it
Build a monetization switch you keep turned off
Some of your most valuable assets should sit deliberately unmonetized as optionality. The 42K-product directory with Stripe-verified revenue gets scraped daily and has investors DMing offers to buy access — they keep it free because the switch exists for when they actually need it. Build the asset, gather the data, refuse the easy $20/month tier; preserve the bigger deal that surfaces later.
I was like we can't have such a low activation rate. So the activation rate for me was: when someone signed up, whether or not do they launch a campaign. And that conversion rate I think it was like at 15%. So I decided to change entirely the product, I redone like all the wireframes, we restarted from scratch.
A 15% Activation Rate Is The Signal To Rebuild The Whole Onboarding Flow
Guillaume defined activation as whether a new signup actually launched a campaign, and a 15% rate told him the product was broken. He scrapped the wireframes and rebuilt the onboarding flow from scratch, which eventually pushed activation to 35%.
There's a play for whatever you're stuck on.
