Second-Brain
5 practitioners working with Second-Brain:
every PKM framework is wrong
PARA, Zettelkasten, GTD, Bullet Journal — what each gets right, where each breaks, and the one thing none of them include: you.
Personal AI Operating Systems
Comparison of 12 open-source personal AI systems: AutoGPT, Open Interpreter, CrewAI, Quivr, Khoj, Haystack, Letta, Leon, and more. Stars, features, setup complexity, and recommendations
the routing layer: what comes after the second brain
storage is solved. retrieval is solved. the unsolved problem is routing — matching who you are in this moment to what approach serves you. this is the thesis.
what Tiago Forte got right (and what AI breaks)
a generous analysis of Building a Second Brain. what CODE and PARA contributed to how we think about knowledge — and where AI changes the equation entirely.
why your second brain is dead
the storage-first PKM paradigm was built for a pre-AI world. the bottleneck moved from finding to routing. what you need isn't a second brain — it's a first self.
