Projects
Projects are persistent workspaces where Claude remembers everything. Upload files, set instructions, and build context that carries across all conversations within that Project.
What you can do
Upload reference documents, style guides, and data files
Set project-level instructions Claude always follows
Maintain context across multiple conversations
Organize different work streams (marketing, development, etc.)
Share Projects with team members
Combine with Skills and Connectors for powerful workflows
Real-world example
You create a 'Product Launch' Project with your brand guidelines, competitor research, and target audience data. Every conversation within this Project has access to all that context, so Claude always gives relevant, on-brand answers.
