Memex like products/communities for gathering personal data?

Recently ran into Memex a personal data repository built by Andrew (Brew conf 2018)and realized maybe I'm not alone in wanting to gather structure and explore my personal data from all apps and activities.

Please share if you have hacks, tools, communities or products that can help archive the above.

Tweet thread yielded the following:
