Questions and Answers

Will I still sound like myself?
Yes. ToneShift preserves your wording and intent and only adjusts tone and clarity where something could be misread. You stay in control of what gets sent.
How does ToneShift know how my message might come across?
ToneShift analyzes wording, structure, and context signals to predict how a message is likely to be interpreted, then flags areas that could feel unclear, blunt, or misaligned.
How is this different from just rewriting my message with AI?
Most tools rewrite messages based only on how you sound. ToneShift focuses on how the recipient is likely to respond, using communication personas to understand how different people interpret tone, urgency, and wording. It adjusts your message so it lands the way that type of person expects without changing your intent, resulting in fewer misunderstandings and better responses.
Do I have to choose a tone every time?
No. ToneShift automatically detects the situation and suggests the appropriate tone. You can adjust it if you want, but you don’t have to.
Are my messages stored or shared?
No. Your messages are not shared or made public, and you can clear your analytics data at any time.
