$1M+ in daily revenue 🤯
Mixed feelings, as
@levelsio
and
@dannypostmaa
were first. But it confirms my thesis that "normal people" don't know how to upload photos to a website.
Photos are locked in their phone so a mobile app can offer a more streamlined UX to the masses
This mobile app called "Lensa" is going crazy right now, doing $1M+ in revenue per day, growing rapidly. (see img below)
It uses Stable Diffusion to create AI images of anyone if you give it 20 images.
Some people see new tech and get fearful, others see opportunity.

One fun Tailwind CSS trick I came up with is creating my own role-based variants.
For example to show certain elements only to admins, I make my body look like: <body data-admin> and add the classes "hidden admin:block" to any elements that should only be visible to admins

You might be able to copy a (successful) product, but you probably can't copy the conditions that made it succesful.
So stop copying other products thinking you'll get the same success.
Study how they learned what to build given the conditions at the time. Copy that process.

Not scared enough to avoid the task, but scared enough to want to be as good as we can be.
We pay more attention, work a little harder, push a little further.

✨ My rule for memorable domain names: your domain name can only have 2 parts that need to be remembered. So either:
1️⃣ Dictionary word + Non-standard TLD
2️⃣ Dictionary word + prefix/suffix + .COM
