Finds legal open-access copies of scholarly papers while you browse.
Use it when
Students, researchers, and operators who need legitimate access to research papers.
Why this is powerful

- Works in the browser flow where paywalled articles are discovered.
- Saves repeated manual searches across repositories and author pages.
Tradeoffs to know
- It cannot unlock papers that have no legal open copy.
