The amnesia is the default, not a bug you caused
After this, you'll be able to name exactly why Claude forgets you between conversations and describe the two systems that fix it, so you stop re-pasting the same context into every new chat.
Before you start
Complete Conversation history: what Claude remembers (and what it forgets) first; this lesson builds on the session-versus-permanent-memory distinction you learned there and turns it into a fix.
The idea
Every Claude conversation starts from zero. You explain your job, your tone, your client, your goal, and get great answers. The next day you open a fresh chat and Claude has no idea who you are.

That is not a fault you caused. Every new conversation is a blank slate by design, because the detail of one chat does not flow into the next one on its own. Two features fix this: Projects (a workspace that holds your standing context) and Memory (a summary Claude builds from your past chats).
Here is the before and after: Before, a copywriter retypes the same 120-word brand brief at the top of every chat, five days a week, twenty-five times a month. After, she saves it once as Project Instructions and just types "draft a re-engagement email," and Claude already knows the brand and the tone.
Now try it: open the chat you used most this week and count how many top lines are background you have typed before. Three or more lines means you have found your repetition.
Re-explaining yourself to Claude is a setup problem, not a prompting problem.

Watch out for
Paste this into Claude
I use you regularly for the same kind of work, and I keep re-explaining my context in every new conversation. Help me see the pattern clearly. Here is the background I usually paste at the start: [paste the paragraph of context you typically retype, or describe it: who you are, your tone, your audience, any rules you always give] Please do three things: 1. List the pieces of this that almost never change (these are good candidates for permanent Project Instructions) 2. List the pieces that change per task (these stay in the individual message) 3. Estimate how many times per month I am retyping the unchanging parts, and tell me in one sentence why moving them out of every message would help
What good looks like
When this breaks
AI can help with this
Open Claude and paste this: 'I keep re-explaining the same background in every new chat with you. Here is what I usually say: [paste it]. Tell me which parts never change and which parts change per task, so I know what to set up permanently later.'

You can now
You can complete the lesson outcome in a real Claude chat, Project, Artifact, Connector, Desktop, or Code surface.
Key takeaways
Claude forgets you between conversations by design. Repeating yourself is a symptom; the cure is moving your standing context into a Project while Memory keeps a running summary of what is true of you across chats.
