These labels are your feedback signals for a project feed.

* **Useful**: a solid match for the project
* **Very useful**: one of the strongest matches in the feed
* **Not for me**: not a fit for this project

Use **Very useful** sparingly. It works best as a high-confidence signal for papers you would want surfaced again.

When you choose **Not for me**, you can add a reason:

* **Off-topic**
* **Low quality**

Those reasons help you explain why the paper does not belong, and they provide a clearer negative signal for future recommendations.
