Claude projects vs artifacts: the simple difference

One-sentence answer

Projects are persistent containers for context — uploaded files, custom instructions, and conversation history — that carry across multiple chats. Artifacts are interactive outputs (code, HTML, diagrams, documents) that Claude generates inside a conversation and renders in a live preview pane.

Projects store your inputs. Artifacts are outputs you can preview and share.

A concrete analogy

Think of a project as a folder on your desktop. You put your reference documents in it, add some sticky-note instructions about how you want things done, and open it every time you work on that topic. Everything you need is in one place, and it's there when you come back tomorrow.

An artifact is a file you created while working inside that folder. It's the thing you made — a spreadsheet, a diagram, a draft — not the folder itself. You can share the file without giving someone access to the whole folder.

What projects do

Projects give Claude persistent memory for a specific topic or workstream. Three things they're designed for:

File uploads that persist. Upload a PDF, a CSV, a codebase, or a style guide to a project, and Claude can reference those files in every conversation inside the project — without you re-uploading them each time.

Custom instructions. Set a system prompt for the project — your preferred tone, your team's naming conventions, a persona Claude should adopt — and it applies to every conversation in that project.

Conversation history across chats. Inside a project, Claude retains context from previous conversations. You can pick up where you left off without re-explaining your situation.

What artifacts do

Artifacts are interactive, shareable outputs. Three things they're designed for:

Live preview of generated content. HTML pages, React components, SVG graphics, Mermaid diagrams, and formatted documents render in a split pane right inside the Claude chat. You see the result immediately, iterate by describing changes, and download or share the output.

Sharing outside Claude. You can share an artifact via a claude.ai link (requires the viewer to have a Claude account) or host the HTML on ShareDuo (works for anyone, no account required).

Embedding on websites. Claude's embed code button generates an iframe snippet you can paste into any site. A hosted artifact URL works in an iframe too — no configuration required if you use ShareDuo.

Using them together

Projects and artifacts work well as a pair. A concrete example:

Create a project for your client's brand. Upload their logo guidelines, tone of voice document, and color palette. Add a custom instruction: "Always use the brand's primary color (#5B4FCF) and write in a direct, professional tone."

Now every conversation inside that project produces on-brand output. When you ask Claude to build a dashboard or a slide template, the resulting artifact automatically reflects the brand guidelines — because the project carries that context into every conversation.

When you only need artifacts

• You want to build a one-off tool (a calculator, a game, a form) and share it
• You're prototyping something quickly and don't need the context to persist
• You're demoing something to a client and just need a shareable link

When you only need projects

• You have reference documents that need to be available across many chats
• You're running a recurring workflow (weekly report drafting, code reviews) with consistent context
• You want to keep a long-running thread of conversations about one topic organized

Frequently asked questions

Are projects and artifacts the same thing?

No. Projects store persistent context — files, instructions, conversation history. Artifacts are interactive outputs — HTML, React, SVG, diagrams — you can preview and share. Projects store inputs; artifacts are outputs.

Do I need a project to use artifacts?

No. Artifacts work in any Claude conversation. You don't need to set up a project to build and share an artifact.

Can I share a project the way I share an artifact?

No. Projects are private workspaces — there's no "share project" link. Artifacts are shareable outputs. Share the artifact, not the project.

Do artifacts persist across conversations?

Artifacts stay accessible within the conversation where they were created. To make an artifact available long-term, download it, or host it on ShareDuo for a stable public URL.
