If Claude has started feeling more familiar lately, there’s a reason. Anthropic rolled out persistent memory to all Claude users in March 2026, free and paid plans alike. Claude is now building a picture of who you are across conversations, quietly, in the background.
Here’s what’s happening and how to work with it.
What memory is (and isn’t)
Claude doesn’t save your full conversations. It synthesizes them. After each chat, it extracts relevant details like your role, your preferences and how you like responses formatted, then stores those as a running summary. You can view and customize Claude’s memory features by going to Settings > Capabilities > Memory. “Search and reference chats” and “Generate memory from chat history” are on by default, and you can click on “View and manage memory” to see what Claude has stored.
Two ways memory gets built
The first is automatic. Claude picks up on things you mention and adds them over time. The second is intentional, and it’s faster. In any conversation, you can say “add to memory that I prefer concise responses” or “remember that I work in higher education” and it updates immediately, no waiting.
That second method is where the real value is. The more you intentionally shape your memory profile, the more useful Claude becomes across every conversation.
When you don’t want something remembered
Sometimes a conversation is just a one-time thing. If you spend an hour asking Claude to help you source catering for a meeting, you probably don’t need Claude to suggest sandwich platters every time you open a new chat.
Two easy options: delete the conversation from your history after the fact (Sidebar > Chats > Select chats > Delete) or use login to Claude using Incognito mode in your browser before you start. Incognito sessions don’t get saved to memory or history at all.
“Add to memory”
… is the exact phrase I use when I want Claude to add something to memory. It’s quick and makes a big difference in my Claude experience. Honestly, this is one of my favorite features right now. Take five minutes to check your memory settings, then try telling Claude something specific about how you work and ask it to add to memory!
