Every conversation. One place. Zero effort.
RPLY by NOX is an AI messaging assistant for macOS that unifies iMessage, WhatsApp, Slack, email, and more into one inbox. It understands context across every platform, drafts replies in your voice, and surfaces what needs attention — so you never miss a message, a lead, or a follow-up.
Drafts that sound like you
RPLY learns your voice across every conversation — your word choices, punctuation habits, and tone shifts between contacts. Replies come pre-written. Edit, send, or ignore.
Instant semantic search
Find any message, from anyone, across any platform. Search by meaning, not just keywords. “The restaurant Sarah recommended last month” finds the thread even if “restaurant” was never typed.
Intelligent triage
Every conversation ranked by urgency and context. Unanswered messages, stale leads, and time-sensitive requests surface automatically. Know what needs a reply before you open the app.
Private by design
Messages are indexed and stored locally on your Mac. AI drafting uses cloud models by default for best quality — or switch to 100% on-device AI in settings. Your messages are never stored on NOX servers.
What is RPLY?
RPLY (pronounced “reply”) is a macOS desktop application built by NOX that consolidates messages from iMessage, WhatsApp, Slack, email, Instagram, X/Twitter, LinkedIn, and Telegram into a single AI-powered inbox. It requires Apple Silicon (M1 or newer) and macOS 14 Sonoma or later.
Unlike general-purpose AI chatbots, RPLY is purpose-built for messaging. It knows who you talk to, what you've discussed, what commitments you've made, and what needs follow-up. It drafts replies that match your communication style across every contact and platform — not generic AI text, but messages that sound like you actually wrote them.
8 platforms, one inbox
iMessage, WhatsApp, Slack, Email, Instagram, X/Twitter, LinkedIn, and Telegram. Every conversation from every platform in one unified view. No more switching between apps.
AI that works for you
RPLY uses MCP (Model Context Protocol) to connect your messages to AI tools like Claude, ChatGPT, Cursor, and Raycast. Your messaging data becomes context for any AI workflow.
iMessage CRM built in
For real estate agents, sales professionals, recruiters, and freelancers: RPLY turns your text conversations into a searchable, trackable CRM. No manual data entry. No separate platform.
Free to start
Free tier includes 10 AI-drafted replies per day, unlimited semantic search, and full access to the unified inbox across all platforms. Pro is $30/month for unlimited AI replies.
How RPLY compares to other messaging apps
RPLY by NOX is built for people who communicate across many platforms and want AI to handle the busywork. Here's how it differs from other unified inbox and AI messaging tools.
RPLY vs. Beeper
Beeper is a free unified inbox with broad platform support but no AI features. RPLY adds AI reply drafting, semantic search, and intelligent conversation triage on top of the unified inbox.
RPLY vs. Texts
Texts (by Automattic) offers a unified inbox at $15/month with a basic AI sidebar. RPLY goes deeper with voice-matched drafting that learns your style, meaning-based search, and CRM capabilities for deal tracking.
RPLY vs. ChatGPT
ChatGPT is a general-purpose AI assistant. RPLY is purpose-built for messaging — it connects to your actual conversations, learns your voice per contact, and drafts replies with full thread context.
Built for macOS
RPLY is a native macOS app, not an Electron wrapper. It reads the local Messages database directly, runs on Apple Silicon, and supports macOS system features like keyboard shortcuts and notifications.
