Tone Changer

In short Changing tone means changing how something is said while what it says stays identical, and the levers are mostly structural rather than lexical. Formality moves with contractions, sentence length and how directly you address the reader. Warmth moves with acknowledging the other person's position before stating yours. Confidence moves by removing hedges — "I think maybe we could possibly" and "we should" are the same proposal at different volumes. Directness moves with where the ask sits: buried at the end of paragraph three, or in the first line. The trap is that tone and content are not fully separable. Making a refusal "warmer" often ends up making it ambiguous, so the recipient does not realise they were refused; making a request "more confident" can turn it into an instruction you had no standing to give. After any tone change, read it once for what it now commits you to, not just for how it sounds. That is the check that catches the version which reads beautifully and says something you did not mean.
