Free tools

Useful research tools you can use without signing in.

Clean links, organize sources, generate tags, and prepare public research shelves before creating an account.

When to move from tools to a shelf

You keep searching the same topic

When the same sources keep coming up, a tagged shelf is faster than another notes document or browser folder.

You want to share sources cleanly

Public directories are useful for newsletters, course pages, hiring notes, research memos, and product teardown references.
