What if your AI remembered everything -- and briefed you every time you sat down to work?

Jacob and Mike Thomson walk through how they each set up persistent memory AI workflows, also called AI second brains, and what that actually looks like in daily use.

Jacob starts by explaining how he installed an AI second brain template and what it changed about how he works. Mike goes deeper with his own fork of the same system, built around two custom skills that most people haven’t thought to add.

The first is a “session close” skill - when Mike finishes a work session, the AI automatically writes a memory log summarizing what was done, what decisions were made, and what’s still open. The second is a “session open” skill - when he starts a new session, the AI reads that log and briefs him on blockers and next steps before he types a single word.

The result is an AI that doesn’t start from zero every time. It knows where you left off.

This is one of the clearest practical explanations of persistent memory AI workflows you’ll find - no hype, just two builders showing what they actually built and how it works.
