Founded in 2007

Hi, I'm Christopher Blum, Founder and Developer behind SpellBoy.
I live in a small suburb near Hamburg (Germany). In 2007, I was frustrated with the current state of spell checking technology and decided to build an easy accessible web-based spelling and grammer checker that is not only free to use but ahead of other tools. Until today more than 8 million people around the world have used it.
I would be happy to hear your feedback.
