Reusable writing templates where AI drafts the body and you keep the soul
Save a structure once and swap the personalized details — names, roles, specifics — per recipient, so the body adapts without rewriting.
Start from templates for proposals, cover letters, cold emails, reports, newsletters, onboarding, performance reviews, and life-event notes.
Let the tool produce the routine parts of a message while you supply the few sentences that carry the real signal.
Strips out the greeting, framing, and obligatory close so your writing sounds like a person, not a form letter.

An AI assistant that remembers your relationships and writes in your voice
Morning and evening briefs, in-app or by text, showing who needs you, what changed, and what you promised.
Before a call, see the decision, open questions, last useful detail, and the follow-ups that are now due.
Ask Rytr questions and get answers grounded in your own connected email, chat, calendar, and notes, with sources shown.
Draft emails, posts, and pages using your personal tone or one of 22 presets, in 38 languages, with up to three drafts at once.
