I use Graphite for my most personal and private writing. This way I know Google, Apple or Facebook aren't snooping on my personal info.
Pros:- Secure - Private - Easy to use - Great Collaboration Features
Cons:Could use more integrations with other publishing or productivity tools but I understand there are trade offs of privacy to add those.
Looking forward to more features from the Graphite Team in their excellent products.
Pros:I like that Graphite is ethical about my data. I won't have an unknown price to pay years down the road for using "free software".
Cons:I don't know of a better alternative. At times some of the flows or operations take a moment as they're not always intuitive to me.
