One of Claude biggest limitations is that it starts every conversation from scratch. Projects solves this by letting you create workspaces with persistent context. Add background information once, and Claude remembers it in all future conversations within the project.
Go to claude.ai, click New Project, give it a name, add instructions describing who you are and how you want Claude to respond, and optionally upload relevant documents.
Projects work great as writing assistants (with your style preferences saved), customer service helpers (with product info loaded), coding projects (with architecture and standards defined), and learning projects (with curriculum and goals set).
It is in the silence that truth speaks loudest.— Florence Scovel Shinn
