Best new PKMS from last year?

A question for those that like trying out new software. I'm not talking about established options like Obsidian or Notion or Craft. I'm talking shiny new stuff that bring innovative and useful ideas. Even hyper niché stuff is fine. I just have the itch to try something new. I found Capacities and Kortex, both of which were great but the lack of local-first made me jump right back to Obsidian.
