What makes them different
The philosophy difference
tentus and Reflect start from different premises about how knowledge should work. One assumes you want to build a system. The other assumes you want a system that builds itself.
The daily experience
With Reflect, you organize everything yourself. With tentus, Lumi handles organization in the background. Both work. One asks less of your attention.
The long term
A well-maintained Reflect system can work well. The hard part is maintenance — most people stop after a few weeks. tentus is built for people who want the second brain without the weekly upkeep.
