Growth Engineer Marvin tested more than 18+ AI tools across real business workflows, comparing their capabilities for writing, coding,
There are more AI tools than anyone has time to properly test. One writes your emails, another takes meeting notes, another builds apps, and another plans your calendar. By the time you have figured out which ones are useful, five more AI tools have launched.
I wanted a simpler answer: Which AI platforms are worth making part of your workday?
So I spent several weeks trying more than 30 of them on the kind of work that fills an ordinary week. I researched topics, drafted content, sat through meetings, planned my schedule, built small apps, debugged code, and handed repetitive tasks over to AI.
A lot of tools were interesting the first time I opened them. The ones that made this list were the ones I kept reaching for days and weeks later.
I kept the 21 platforms that proved useful after the first test and still gave me a reason to come back.
