What Is the Projects Feature? Turning One-Off Chats into a “Business AI”
Projects in Claude Pro is not merely a feature for saving conversation history. By packaging goals, tone of voice, reference materials, and work rules into each project, you can create a “specialized AI” that excels at a specific task—without needing to explain everything from scratch every time. That is the biggest value of Projects.
For example, in a typical chat, each time you must preface with something like, “You are the in-house help desk representative. Based on the attached employment regulations and expense reimbursement manual…” On the other hand, with Projects, you can lock this into the project as Custom Instructions and a Knowledge Base. As a result, answer variation decreases, and you get much higher reproducibility even for internal use.
Projects are well suited for use cases like the following.
- Help desk AI that reads internal manuals
- Sales support AI built from product specification documents
- Article-writing AI that learns your company blog tone
- Inquiry AI by department, such as legal, HR, and accounting
Basic Structure of Projects: Focus on Three Elements
Projects is easiest to understand if you think of it as three main components: the project itself, Custom Instructions, and a Knowledge Base.
| Element | Role | Setup Tips |
|---|---|---|
| Project | A container that groups conversations and documents for a specific purpose | Split by purpose, such as “HR FAQ” or “Sales Proposal Creation” |
| Custom Instructions (Equivalent to System Prompt) | Fix the AI’s role, answer policy, and prohibited behaviors | Write not only the target audience and output format, but also reference priority |
| Knowledge Base | The set of documents you want the AI to reference | Insert only the latest official versions and reduce duplicate documents |
A common stumbling point for beginners is assuming that once you add documents, the system will automatically become perfect. In reality, it becomes more stable when you also instruct which documents to prioritize and how to respond when something is unclear.
How to Create a Project
1. Decide the purpose first
Start with one project, one job, rather than trying to build “an AI that can do anything.” Here are example tasks.
- Internal policy Q&A
- Create reply drafts for customer support
- Review sales proposals
- Search specifications for the development team
If you expand the scope too much, both the instructions and the documents get mixed, and answer quality drops.
2. Create a new project
From the Projects screen in Claude, choose “Create new,” and enter the project name. Pick something that won’t confuse you later. A good recommendation is department name + purpose + version.
