Hey, good question. Rem and it's closed source competitor Rewind capture everything on your screen. Zenfetch only captures information that you explicitly add to Zenfetch. We've found that using a curated approach as opposed to capturing everything allows us to do two things:
1. Return much higher quality answers than Rem/Rewind as the information we store are items you thought were important at some point.
2. Allow us to help you remember that information with proactive features like our recap emails.
