About Promptowl
Cloud memory forgets why it changed something. Here's how to build a second brain with Claude and a governed context layer, and follow along step by step. Ask Claude or ChatGPT to remember something and it will, for that conversation. Projects help, but unless you actively update them, the context drifts and you have to repeat the details in every new chat. Markdown-based second brains are how you organize your knowledge to solve the persistent memory problem.
