For PKM I fell in love with Capacities and I use Ask Rewind constantly to up my productivity. Rewind is an AI layer over all other apps. "What did I last talk about with Tom Solid?" will get back to this tweet and tell me what I noted in my Capacities when I saved it there.
The most underrated AI tool is @RewindAI by far. Nothing comes even close to this productivity powerhouse!
This AI Tool is Real Life Jarvis.
GPT-4 is now connected to everything I do on my mac.
I can ask it questions, have it summarize an article I read a week ago, and have it search for anything that I've seen, without having to manually press save, ever.
First tool I've used…

Its particularly useful for me because I jump around to 10-15 customers per day. Before a meeting I can remind myself about a customer's history. If I don't have time to summarize and take notes because I'm back-to-back all day I can star certain moments I know I want to revisit.
If you're not using @RewindAI at this point you're seriously missing out on huge productivity gains.
It helps me recall information from meetings quickly, go back and snag screen captures of things that I may not have known I would need later on, summarize meetings, open hyperlinks that were shared on screen to me, etc. And with the recent integration of GPT, I can ask it…
ever since @RewindAI came I out, I've completely given up on most note taking. the inertia of organizing thoughts and remembering to do it was always too high. Being able to search through any thing you've ever seen + heard is the correct and superior UX
