This hidden Claude feature saves me hours every week, and most people don't know it exists

Claude Projects is a persistent workspace feature inside Claude that lets users store custom instructions, upload files, and retain conversation history across sessions. Instead of re-uploading context and re-explaining goals every chat, users set up a Project once and Claude remembers everything automatically. The author shares a real-world example managing content for a jewelry brand, where consistent tone, style guides, and specs were stored in a single Project, eliminating repetitive setup work. The feature requires a Claude Pro subscription and supports up to 200,000 tokens of context.
