Paste any draft and shift it to the tone you actually meant — formal, friendly, concise, diplomatic, encouraging, or plain English. Slide intensity for a light tweak vs. a full structural rewrite.
Heuristic mode swaps words and adds tone scaffolding but can't truly rewrite voice. Add an Anthropic or OpenAI key in Settings to unlock natural, context-aware rewrites.
The heuristic only works on English text. For other languages, switch on AI mode in Settings.
Paste a draft, pick a tone, slide the intensity, and hit Shift it. The rewrite is editable — click to tweak before copying.
Bring your own API key for natural rewrites.
