Projects, announced by Anthropic in June 2024, lets Claude Pro and Team users group chats, files and custom instructions in one workspace. If you’ve been juggling multiple Claude conversations or repeatedly uploading the same documents, this organizational tool might change how you work with the chatbot.
Projects essentially creates workspaces inside Claude where you can store related conversations, upload reference documents, and set custom instructions that apply to everything in that project. Think of it as a dedicated folder with memory.
What Projects Actually Does
When you create a Project in Claude, you get three main components: a place to keep related chats together, space to upload reference files (like PDFs, CSVs, or text documents), and a custom instruction field that acts as a permanent system prompt for that project.
The custom instructions are the most powerful part. Instead of copying and pasting your tone preferences, output format, or role description into every new chat, you write it once. Every conversation you start within that Project automatically includes those instructions without cluttering your actual prompts.
For example, if you’re using Claude to draft marketing emails, you could create a “Marketing Copy” project with your brand voice guidelines uploaded as a PDF and custom instructions like “Write in a conversational tone, avoid exclamation points, keep paragraphs to two sentences max.” Every new chat in that project starts with that context already loaded.
How It Compares to ChatGPT’s Projects
ChatGPT has its own Projects feature. If you’ve used it, Claude’s version will feel familiar but with some differences. Both let you group chats and set custom instructions, but Claude puts more emphasis on document uploads as reference material.
ChatGPT Projects integrates more tightly with Custom GPTs, while Claude’s Projects are simpler—just conversations, files, and instructions. There’s no option to publish or share a Project the way you can share a Custom GPT. It’s purely for personal or team organization.
One advantage Claude has: uploaded documents in a Project persist across all chats within it. You don’t need to re-upload a style guide or data file every time you start a new conversation. ChatGPT Projects works similarly, but Claude’s document handling has generally been stronger for large or complex files.
When Projects Are Actually Useful
Projects shine when you have ongoing work that requires consistent context. A few practical scenarios:
- Client work: Create a project for each client with their brand guidelines, past deliverables, and tone instructions. Every new task starts with that context already loaded.
- Research: Upload papers, notes, or datasets into a project and have multiple conversations that all reference the same material without re-uploading.
- Writing projects: Keep drafts, outlines, and style rules in one place. Start new chats to revise or expand without losing continuity.
- Learning a topic: Build a project around a subject with reference materials and custom instructions to quiz you or explain concepts at a specific level.
Projects are less useful if you’re just using Claude for one-off questions or quick tasks. The overhead of setting up a project only pays off when you need that context repeatedly.
Limitations to Know About
Each project has a 200K-token context window, about 500 pages of text, per Anthropic’s announcement (checked October 2026). That’s generous for most use cases, but if you’re trying to upload an entire textbook or codebase, you’ll hit limits.
You also can’t share Projects publicly or with people outside your team plan. If you want to distribute a configured version of Claude to others, you’re out of luck—this is strictly for personal or internal team organization.
And like all Claude features, Projects only exist within Anthropic’s ecosystem. If you switch to ChatGPT or Gemini, you’ll need to recreate your setup from scratch.
Should You Start Using Projects?
If you’re already a Claude Pro or Team subscriber and you find yourself uploading the same files or typing the same instructions repeatedly, Projects will save you time. The feature is included in your subscription—there’s no extra cost or setup complexity.
For casual users on the free tier, Projects isn’t available. You’ll need to stick with individual chats and manual context-setting. But if you’re on the fence about upgrading, Projects is one more reason the Pro tier makes sense for professional or consistent use.
The feature is live now and accessible from the Claude sidebar. You can create as many Projects as you need, though most people will probably settle into three to five for different work areas.
