What does the Tone Converter do?

Tone is the single biggest factor in whether your writing lands or falls flat. The same information delivered in a formal report style will bore a social media audience. A casual explainer aimed at experts will irritate them. The Tone Converter lets you write once and adapt for any context — no rewriting from scratch, no guessing how it will come across.

It preserves your meaning and structure while changing vocabulary, sentence rhythm and register to match the target audience.
