How to Index a Codebase in Cursor

‍

‍

Indexing allows Cursor to scan your project files so the AI can understand and reference your entire codebase.

‍

1. Open your Cursor editor and sign in to your account.
2. Click "File" from the top menu of the editor, and select Open Folder.
3. Select "Open Folder" and choose your project folder (codebase).
4. Click "Select Folder" to load the project into Cursor.
5. Wait for the Cursor to automatically start indexing the files in the folder.
6. Open the AI Chat panel from the right sidebar and ask a question about your codebase to confirm the indexing is complete.
7. Once Cursor can reference your files, your codebase is successfully indexed and ready to use.
