  • Professor

    Why Redis? What property of the problem makes it the right tool?

Make it yours.

Tell Riddled what any note is for, or how to be in it, in your own words: “Quiz me before Friday,” “Just let me vent,” “Very funny.” And pick the ink it writes in.

It won’t think for you.

It won’t rewrite your notes, hand you every answer, or interrupt every passing thought. The page is yours. Riddled just asks the questions you might have missed.
