The idea: Maintain a PROJECT_JOURNAL.md file that documents your project's story - decisions, progress, status, next steps.

The AI reads it at session start (full context) and updates it at session end (persistent memory).

I've been using this building Vibe CMS. Results: - Zero time wasted re-explaining - AI maintains consistency - Natural documentation - Better decisions (you write WHY)

Made a free template (CC0): https://github.com/CursorWP/ai-project-journal

Works with Claude, ChatGPT, Copilot, any AI.

Would love HN's feedback on this approach!
