Lesson 2 of 8
Projects
6 min read
You start a chat about your launch on Monday, another on Wednesday, a third on Friday — and re-explain the product, the tone, and the goal every single time. What if every chat just knew?
A shared home for your work
A Project is a home for the chats about one thing. Load in the knowledge that matters — a brief, past work, a style guide — and every chat inside the Project can draw on it. No more pasting the same background into each new conversation.
A Project keeps your knowledge in one place, so each new chat starts grounded in it — not from a blank page.
Files plus instructions
A Project holds two kinds of knowledge. Files give Claude the facts — your documents, notes, and references. [Project instructions](glossary://custom-instructions) give it the standing rules: who you are, the tone you want, the format to use. Set them once and every chat in the Project follows along.
Files answer what; instructions answer how. Together they carry your context so you don't have to.
Keep a Project focused on one body of work. Piling in unrelated files makes every reply wade through noise — start a fresh Project for a new topic.
The shape of it
- —A Project groups related chats and shares files across them.
- —Project instructions apply your preferences to every chat automatically.
- —Together they mean you set the context once, not every time.
You're planning a wedding across dozens of chats and keep re-typing the budget, the date, and your taste. What removes the repetition?
