# Grounding of AI Copilot on the project level
With the new **project-level AI grounding**, server administrators can upload documentation that will be used **only within a specific project**. This allows teams to tailor AI Copilot’s behavior based on the unique context, terminology, and processes of each project — without affecting others.
### **What is project-level grounding?**
Files uploaded at the project level are only used by AI Copilot when:
* A user asks a question in the **AI Copilot chat** within that project
* A user generates **requirements**, **test cases**, or **test data** inside that specific project
This keeps responses relevant and localized to the project’s specific domain.
#### **How to upload**
* Go to **AI Copilot → Configure AI Copilot**
* Open the **Project level** tab
* Select the target project
* Click **Upload file**
Once uploaded, the file will be **processed in the background**
When ready, it appears in the file list and is available for grounding.
You’ll receive an notification while the file is being processed. No need to wait — we’ll let you know when it’s done with an email.
#### **Reusing files across projects**
Need to use the same reference in multiple places? No problem. You can **reuse already uploaded files** across projects using the **Reuse files from library** option.
**Here’s how it works:**
* A file added to one project can be attached to others without re-uploading
* If a file is **deleted from one project**, it’s only removed from that project
* The file **remains active** in other projects where it’s still in use
* To remove it completely, the file must be deleted from **all projects** it’s linked to
**Supported file formats**
* **.txt**
* **.docx** (text only)
Other formats (like PDFs or URLs) are currently not supported but may be considered in the future.
**Storage and file management**
* The total project file size limit is **10 MB**
