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

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.
