Why are there so many of these in the last 2 days?

AI means that anyone at all can pay tiny amounts of money for software that fits their exact needs.

This excites them and they share it under the assumption someone else has their exact needs but lacks the inclination to have AI make one of their own.

The real question is why does HN keep upvoting them?

>The real question is why does HN keep upvoting them?

Because a significantly large demographic of HN is aggressively pro-AI to the point of cultishness and the mere existence of such applications, to them, is a vindication of all of their beliefs and an expression of triumph over all of the critics and doubters.

Note that it doesn't actually matter how well they work, or whether they work at all. Many people will assume by default that they do, and that anyone claiming otherwise is just a deluded, bitter Luddite, and will praise and defend them regardless of quality. The rules and standards that apply to human written software don't apply to AI generated software.

There have been at least 10 (probably more) photo editing suites. It seems that now everyone who doesn't want to learn the existing suites just can make their own with AI.
