It's not a hyperbole. I know how long it takes me to do something.

And the last project truly would have taken me 6 months.

It was done in 3 days after fable 1:1 the design, setup the infrastructure, and turned all tasks and specs into code.

Everything was done day 1, but it took 2 days to manually clean it, test, and correct small issues.

But that does make sense you're seeing "hyperboles" grow, AI is getting better very quickly, so you'll see the time saved estimations grow.

Less than a year ago I'd say it was saving me about a month of work, mainly because it sucked at UI.
