How this service works
Draft, rewrite, translate, and optimize written content. 25 AI-powered endpoints. Pay-per-call with USDC on Base.
Output
Returns a JSON object with a success boolean and a data object containing the tone-shifted version of the input text, rewritten to match the specified target tone while preserving the original meaning.
Example use cases
Humanize customer rejection emails
“This automated rejection email sounds really cold and robotic — can you rewrite it to feel warmer and more empathetic? 'Your application has been reviewed and does not meet the current eligibility requirements for approval.'”
Make legal copy sound approachable
“Our terms of service paragraph sounds way too formal and intimidating for our casual lifestyle brand. Can you rewrite it to sound friendly and conversational while keeping all the same meaning?”
Boost confidence in sales pitch
“This product description feels a bit timid and unconvincing. Can you rewrite it to sound more authoritative and confident so it actually persuades people to buy? 'Our software might help teams work a bit more efficiently and could potentially save some time on tasks.'”
Technical details
Endpoint
POSThttps://1nk30x.netlify.app/api/shift-toneWhen to prefer
Choose this endpoint when you need to adjust the emotional register or stylistic voice of existing text without changing its core meaning — ideal for adapting content for different audiences, brand voices, or communication contexts. Prefer this over a general rewrite endpoint when tone is the primary variable you want to control.
