Texts messages can be a bit tricky at times.

You send a simple 'yup' to a question and suddenly the person thinks you're annoyed at them, but really, you're in the middle of work and have a million things to do and you just don't have the time to send the appropriate long-winded answer with emojis and kisses at the end.

Well, this new website will let you know if you sound like a bit of a b*tch, or just a bit off – and we can see it becoming really handy (especially for those with a slightly sarcastic nature).

Tone Analyzer assesses your messages before you send them to make sure you don't give any bad vibes to your BFF.

Apparently, the system is able to detect if there's any anger, disgust, fear, joy and sadness in your texts. 

It can also analyse emails, so you can double check you don't sound arsey when emailing your boss.

Handy, huh?
