Claude has been quietly building a picture of who you are for months, and some of it is out of date. Here’s the audit prompt that fixes it in 10 minutes.
Claude’s memory is on by default on the Free, Pro, Max and Ultra plans. It remembers your work, your tools and your goals, and it adds topics to memory as you chat. (Claude’s memory update)
The catch is that a one-off question you asked at midnight can end up in that picture next to the real facts about you. A few months in, Claude is working from a profile that’s half right and half stale. This is the audit I run on my own Claude every couple of months.
When an answer feels almost right but not quite, the cause is usually a weak prompt or stale memory. You can see a prompt and rewrite it. Stale memory is invisible. You don’t see which old assumption about your role or priorities Claude pulled in.
The audit makes it visible. You read what Claude thinks it knows, line by line, and decide what stays.
Paste this into a new chat in Claude. It runs in three rounds and takes about 10 minutes if you answer properly.
Run It Quarterly
I run this once a quarter, and Claude’s answers get noticeably sharper the week after. Put it on your calendar for the first Saturday of every quarter. 10 minutes, done.
On an older layout, look under Settings, then Memory. Sensitive topics like health aren’t saved unless you turn them on. (Claude’s memory help page)
Skip the pasting. I turned the audit into a Claude Skill, so you can just say "run my memory audit" and it starts.
Each time, save the final report as claude-memory-YYYY-QQ.md in a Project or your Drive. When an answer feels off two months from now, check the last report to see whether it’s new drift or something you already fixed.
After three or four audits you’ll spot patterns in yourself too, like the workflows that stick, the priorities that keep coming back and the tools you drop.
The Wider Rule
Any AI that remembers you needs this audit, ChatGPT included. The prompt works there too. The goal is simple: no AI should be using a six-month-old version of you to help with today’s decisions.
