AI tool: "memory" @ Claude

The Claude memory tool is a feature that allows Claude to learn and remember information across different conversations by storing and retrieving it from files on your system. Instead of starting each new chat from scratch, Claude uses this memory to maintain context, improve productivity, and build on previous interactions. This enables it to learn your workflows, remember project details, and act as a more knowledgeable collaborator over time.
