What people are saying

"The anagram solver settled a family Scrabble argument that had been going on for three Christmases. 370,000 words in the dictionary and it found every single valid combination in less than a second. Bookmarked permanently."

"I calculated my GPA every semester to make sure I stayed on track for my scholarship. Most GPA calculators online are covered in ads or want you to create a student account. This one just works — clean, fast, done."
