AI-powered proposal platform for closing deals faster
A sales-tuned GPT-4-based model drafts a client-ready proposal in about 30 seconds, with adjustable tone, structure, and content in over 29 languages.
Teammates edit, comment, and update the same proposal simultaneously, so multi-stakeholder documents move forward without email ping-pong.
Acceptances are signed under eIDAS, ESIGN, and UETA standards, with IP address, timestamp, and consent tracking recorded for a clear audit trail.
Track when and where a client opens or accepts a proposal, then use that signal to follow up at the most promising moment.

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.
