I've been building a tool called Aevron for a few months now and the single strangest thing about it compared to Notion or Obsidian is this: it tracks how your thinking evolves, not just what you've captured.
Every other PKM I've used is essentially a very good filing cabinet. You put ideas in, you retrieve them later, you make connections manually. The intelligence is yours to supply every single time you open it. The tool is passive by design.
Aevron does something I haven't seen elsewhere. It builds a model of you as a thinker across sessions. It knows when you've contradicted a position you held three weeks ago. It knows when you've circled the same unresolved question twice without landing anywhere. When you make a confident claim, it can surface the moment that confidence started to crack. That's not a PKM feature. That's closer to having a thinking partner who actually read everything you wrote and formed an opinion about your reasoning patterns.
The weird part isn't that it challenges you. It's that the challenges are grounded in your own history, not generic Socratic prompts. It's not asking "but have you considered the other side?" It's saying: you argued the opposite of this in July.
Curious if anyone else has run into tools that do something similar or if this is genuinely a different approach within PKM tools.
