Papaly is a bookmark management and discovery tool. We exist to make your web browsing a little easier by helping you save and organize your bookmarks into collections called boards. Inside each board, you can have multiple categories with related links. Use these boards to build a collection of bookmarks related to a topic. Maybe a collection of your favorite blogs or blog posts about a subject, or a collection of bookmarks about science and technology. We are an independent, privately held company headquartered in Palo Alto, California.
