Tone Guard

The pause before you press send.

Tone Guard reads each message as you write it and flags the phrases most likely to start a fight: absolutes, blame, old grievances, threats. It offers a calmer version that keeps everything you actually needed to say.

The pause before you press send.

You will recognise these

The message is right and the tone is wrong

You are correct about the pick-up time. The way you said it means you will not get an answer about the pick-up time.

Nobody rereads at midnight

The messages you regret are the ones sent fast, late and angry.

Calmer does not mean weaker

Dropping the request to avoid the fight is not the answer. Keeping the request and dropping the fight is.

What Tone Guard does

Flags escalating phrases as you type
“You always”, “you never”, character judgements, references to last time, legal threats.
Suggests a calmer version
Same facts, same request, same dates, without the parts that provoke a defensive reply.
Stays out of the way
Calm messages pass without comment. Tone Guard only appears when something is likely to land badly.
Works on every message
Not a separate tool to remember. It is in the message box, every time.
