Show HN: Microlearning apps with a TikTok-style feed to beat doomscrolling

I wanted to kick my doomscrolling habit, so I built a microlearning app that uses a TikTok-style algorithm, same addictive feed mechanics, but you actually learn something.

I started with a general version, Scroll: Daily Microlearning (microlearning.usescroll.app), but quickly realised it works better when focused on a single topic. So I split it into:

Scroll: Personal Finance (https://finance.usescroll.app)

Scroll: Learn AI (https://ai.usescroll.app)
