Tools to make going and staying NC easier

What tools do you wish you had to support your decision to go NC? Or, if you are still early stages/years into NC, what tools do you feel like you could still use?

Really curious to hear thoughts (and maybe get some ideas for projects that would serve some good). Also, it's likely someone will read your comment and maybe discover an existing tool or something you found helpful, that could in turn help them.

I'm 17 years NC, so I'm past the early stages and wonder what has evolved as far as tooling in this regard and where there are still gaps. I see there's far more books and general awareness than when I went NC, but a lot of that struggle was something I had to do on my own, with some support from my partner. It felt really isolating. Is this still what the journey is like, or are there tools that make it a little easier?
