If you keep pasting the same background information into Claude every time you start a chat, Projects will save you a lot of effort. A Project is a workspace that remembers your instructions and reference files across every conversation inside it. Here is how to use one.
What a Project gives you
A Project has two parts that persist across all its chats:
- Custom instructions - how Claude should behave in this Project (tone, role, rules, what to always do or avoid).
- Project knowledge - files and text you upload once that Claude can draw on in every chat.
That means you set your context a single time, and every conversation in the Project starts already knowing it.
Step 1: Create a Project
In Claude, create a new Project and give it a clear name for the work it covers, for example “Newsletter” or “Client X website copy.” Keeping one Project per distinct job keeps its knowledge focused and relevant.
Step 2: Add custom instructions
Write instructions that apply to everything you’ll do here. For example: “You are writing for [brand]. Keep the tone warm and plain. Always suggest a subject line. Never use hype words.” These apply automatically to every chat in the Project.
Step 3: Add knowledge
Upload the reference material Claude should always have: a style guide, product notes, examples of good past work, templates. Now you can ask “write a launch email” and Claude already knows your voice and details, without you re-pasting anything.
Step 4: Work in chats
Start new chats inside the Project for each task. They all share the same instructions and knowledge, but stay separate conversations, so your work stays organized and consistent.
A good habit
Keep Project knowledge tidy and current. Remove outdated files and add new examples as your standards evolve, so Claude’s context always reflects your latest, best work.
