If you've spent any real time with Claude Code, you know this pain: you open a fresh session and it's forgotten everything you taught it yesterday. I'd tell it over and over not to dump a pile of emojis into my writing because it looks too AI — and the next morning, fresh session, emojis everywhere again.

Turns out there's a fix built for exactly this, called Auto Memory. I'd already written about CLAUDE.md for setting project rules by hand, but Claude Code's memory system is bigger than just CLAUDE.md. Auto Memory quietly records your corrections and preferences as you work, so next session you don't have to say them again.

Auto Memory needs Claude Code v2.1.59 or newer. Check with claude --version.

Auto Memory vs CLAUDE.md

A lot of people mix these two up, so let's get it straight first.
