Having to pay $15/month ($180/yr!) to be able to search stuff on my own computer for years seems awfully expensive. I'd rather depend on some simple open-source piece of software that I can understand and maintain if necessary.
Yeah, the sheer idea of paying a subscription for software that is running on my computer to index local resources is crazy. This kind of software should be should sold as one-time buy license.
Decades ago there was an amazing piece of software from lotus when I worked there called magellan. I remember the first time I saw someone search, and find results in text documents, spreadsheets and many other of the common formats of the day.
That was in 1989 and today I mostly search my computer using find and grep commands, since that's what just keeps working.
