Here is a pattern you have probably lived: you open a fresh chat with Claude, and before you can ask for anything useful, you spend three paragraphs explaining who you are, what your company does, and what you are trying to get done. Tomorrow you do it again. A Claude Project ends that. It is a workspace that holds your files and carries the same instructions into every chat, so you set it up once and skip the re-introduction from then on. Setting up your first one takes about fifteen minutes. Doing it is a small step up The 7 Levels of AI Proficiency, the scale for where you stand with AI, from asking it questions to building it into how your work runs.
Every product detail below is from Anthropic's own documentation, checked the day this was written.
What a Claude Project is
Anthropic puts it simply: projects let you "create self-contained workspaces with their own chat histories and knowledge bases." A Project bundles three things in one place:
- Project instructions: standing guidance for how Claude should behave and respond, like your role, your audience, and the rules you want followed every time.
- A knowledge base: documents, text, and files you upload once, which Claude reads and uses as context inside the project.
- Chats: every conversation you start in the project, kept together and all sharing the same instructions and knowledge.
Projects are free for everyone. Free accounts can create up to five projects. When a project's knowledge grows past the context limit, Claude automatically switches to a retrieval mode (RAG) that expands its capacity up to ten times, on any plan.
When a Project is worth setting up
You do not need a Project for a one-off question. You want one when the same context shows up again and again. Good first candidates:
- A recurring task you do in your role, like writing client updates or drafting proposals in a set format.
- One client, account, or product you work on often, with its own background and files.
- An ongoing effort with reference material, like a policy you keep consulting or a brand voice you keep matching.
If you find yourself pasting the same background into Claude more than twice, that is the signal to make it a Project.
Setting it up, step by step
Four steps, about fifteen minutes. You can do all of this in your browser.
Create the project
Go to claude.ai/projects and click "+ New Project" in the upper right. Give it a name and a short description. Note that these are for you to stay organized; Claude does not read the name or description, so the setup that counts is the next two steps.
Write the project instructions
Click "Set project instructions" and describe how you want Claude to behave across every chat in this project: your role, who the work is for, the tone you prefer, and any rules to follow each time. Save it. These instructions ride along with every conversation, so you never retype them.
Add your knowledge base
Find the project knowledge base on the right side of the page and click the "+" to add content. Upload the documents, text, or files Claude should know: a style guide, a past report to match, product details, a policy. Claude reads this material and uses it as context in your chats.
Start chatting, and reuse it
Open a new chat inside the project and give it a task from your week. Because the instructions and knowledge are already in place, you go straight to the work. Come back to the same project tomorrow and the context is waiting.
A prompt to write your project instructions
Project instructions are the part people stare at with a blank cursor. Let Claude draft them for you first, in a normal chat, then paste the result into step 2.
I'm setting up a Claude Project for [the recurring work, e.g. "writing weekly client updates"]. My role is [your job], and the work is for [audience]. Ask me up to five questions about how I want the output to look and sound. Then write a tight set of project instructions I can paste in, covering my role, the audience, the tone, the format to use, and anything to always avoid. Keep it to what stays true across many chats.
You get a clean draft tailored to your situation, instead of guessing what good instructions look like.
A setup sheet to keep
The companion below is a one-page setup sheet: the four steps, a fill-in-the-blank project-instructions template, and three starter project ideas. Save it or print it and fill it in as you go.

Putting one-off details in the instructions
Project instructions are for what stays true across many chats. The details of today's specific task belong in the chat itself. Keep the instructions about your role, audience, and standing rules, and the project stays useful for months.
Skipping the knowledge base
Instructions tell Claude how to act; the knowledge base gives it the facts. Upload the one or two documents that carry your context, like a style guide or a sample of past work, and the output gets noticeably closer to yours.
Making one giant project for everything
A project works best around a single recurring job or client. If two efforts have different context, give them their own projects so the instructions and files stay clean. Spinning up a new one takes a minute.
Where this fits in the bigger picture
A Project looks like a convenience, and it is. Underneath, it is the first version of something larger: a setup where Claude carries your context, your standards, and your reference material without being told each time. That is the start of designing how your work runs, rather than answering one question at a time.
That climb is what The 7 Levels of AI Proficiency describes, where each level is less about a single chat and more about how much of your work the tool reliably carries. A first Project moves you a rung. If you want to see where you stand and what your next step looks like, the free 7 Levels of AI Proficiency assessment takes about ten minutes and gives you a map instead of a guess.

Frequently Asked Questions
What is a Claude Project?
In Anthropic's words, projects let you create self-contained workspaces with their own chat histories and knowledge bases. A Project holds custom instructions, a set of files you upload, and all the chats you start inside it, so Claude keeps the same context across conversations.
Are Claude Projects free?
Yes. Projects are available to all users, including free accounts, which can create up to five projects. Separately, Claude can use retrieval (RAG) on any plan: when a project's knowledge grows past the context limit, Claude automatically expands its capacity up to ten times.
What is the difference between project instructions and the knowledge base?
Project instructions tell Claude how to behave and respond across every chat in the project, like your role, your audience, and your preferences. The knowledge base is the documents, text, and files you upload for Claude to read and use as context. One sets the behavior; the other supplies the facts.
Does Claude see the project name and description?
No. When you create a project, the name and description are for you to organize your work. Anthropic notes that Claude does not have access to those details. The instructions and knowledge base are what Claude reads.
What should I put in project instructions?
Describe your role, who the work is for, the tone you want, and any rules Claude should follow every time, such as formats to use or things to avoid. Keep it to what stays true across many chats, and let each chat carry the one-off details.
Where do I find Projects?
Go to claude.ai/projects in your browser, or open Projects from the sidebar when you are signed in. Because everything shares one account, the projects you create are there when you sign in on the desktop app too.
