Most people who quit their second brain didn't lack discipline. When life got busy, the maintenance piled up. The system died. This is my talk from PKM Summit 2026. Three use cases where Claude Code removes the admin overhead that kills every PKM system: Your Days - effortless daily logging so your yearly review actually happens Your Work - never drop a ball again, from meeting prep to follow-up emails Your Curiosity - your reading, watching, and learning actually leads somewhere Tools: Obsidian + Claude Code --- Want to build this yourself? LifeStack OS is a 4-week live workshop launching end of April. Free email series + live webinar before the cohort opens: https://lifestack-os.com --- Consulting and demo vaults: https://www.constructbydee.com/ --- I stopped typing Wispr Flow has completely replaced typing for me. Notes, drafts, and messages. If I would normally type something, I speak it instead. https://ref.wisprflow.ai/construct-by-dee --- Timestamps: 00:00 - Why people really quit their PKM systems 02:14 - The three use cases: Your Days, Your Work, Your Curiosity 02:23 - Use Case 1: Your Days (daily logging and yearly review) 11:55 - Use Case 2: Your Work (meeting processing and task management) 22:01 - Use Case 3: Your Curiosity (source processing and idea capture)
