Frequently Asked Questions

Getting Started

RPLY is an AI-native messaging assistant for macOS. It unifies your conversations across iMessage, WhatsApp, Slack, and more into one inbox, understands context, and helps you reply faster, without ever sounding like a robot.

ChatGPT is a general assistant. RPLY is purpose-built for messaging across all your platforms. It knows who you talk to, what you've promised, and what needs follow-up. It's not a chatbot. It's a copilot for your unified inbox.

How It Works

Never. RPLY drafts. You decide. Every suggestion is a starting point you can edit, approve, or ignore. You stay in control of what gets sent.

RPLY learns from your actual messages: your word choices, your punctuation habits, your tone with different people. The more you use it, the more it sounds like you.

Privacy

Messages are indexed and stored locally on your Mac. AI drafting uses cloud models by default for the best quality, but you can switch to 100% on-device AI in settings, no internet required. Either way, your messages are never stored on our servers.

No. Your data stays yours. We don't collect, store, or train on your conversations. The AI improves through general model updates, not your private messages.

Requirements

Any Mac with Apple Silicon (M1 or newer) running macOS 14 Sonoma or later. Intel Macs are not currently supported.

Pricing

Yes. Free includes 10 AI-drafted replies, unlimited search, and full access to the unified inbox across all platforms. Pro ($30/mo) removes the reply limit.
