Common Questions.

Everything you need to know about your AI Twin.

No. Your privacy is our priority. We use encrypted local-first storage and your drafts are never used to train global AI models. Your AI Twin is private to you.
rwrt is designed to solve the 'statistical entropy' gap that common AI models leave behind. Our engine re-injects high-EQ human intent, making the output undetectable by design.
Every time you use a persona or give feedback (likes/dislikes), our engine calibrates your Persona Mastery score. Over time, it moves from a general tone to your specific vocabulary and rhythm.
Yes. You can use the iOS Share Sheet to humanize text directly from Slack, WhatsApp, Gmail, or any other app where you write.
