When playing online with friends yesterday, I had to dictate over phone a short URL with random characters in it. Unfortunately, some characters could have been the letter O or the digit 0 and I was unable to know that!
I quickly looked up for an online tool to help me but I couldn’t find one. That’s why today I release “Letter O or digit 0”, the first online tool to quickly know where are letters O and digits 0 in a text.
