Claude Projects
A self-contained workspace inside Claude.ai where your chats, documents, and instructions live together — so Claude stops forgetting the important stuff between conversations.
Anatomy of a project
A project is made of four slots. Tap any one to see what fits inside.
Knowledge base
Upload briefs, style guides, code, transcripts — anything Claude should always know. Every chat inside the project reads from it automatically. 200K tokens of context per project, expandable up to 10× on paid plans via Enhanced RAG.
With a project vs without
Same question, same week. Flip the toggle to see what changes.
Can you draft a follow-up email for the Acme pitch?

Thanks again for Tuesday. I pulled together a short summary of the three directions we discussed plus a timeline for the first pilot — both attached. I'll send the SOW by Friday as agreed. Shout if anything shifts on your end.
— Jade
