Rexii is a voice-powered AI desktop assistant for Mac and Windows. Press a hotkey, speak naturally, and Rexii turns your voice into action — drafting emails, creating documents, managing tasks, and controlling your apps without ever leaving your current workflow.
Download the installer from our Download page. On Mac, drag Rexii to your Applications folder. On Windows, run the .exe installer. Rexii starts automatically and appears in your menu bar (Mac) or system tray (Windows). No account is required — Privacy Mode works out of the box.
Rexii is available for macOS (Apple Silicon and Intel) and Windows (10 and 11). Browser extensions for Chrome and Firefox are coming soon.
Mac: macOS 12 (Monterey) or later, 8 GB RAM minimum. Windows: Windows 10 or later, 8 GB RAM minimum. Privacy Mode requires approximately 2 GB of disk space for the local AI models. An active internet connection is only needed for Cloud Mode.
Privacy Mode runs all AI entirely on your device using local models. No audio, text, or commands ever leave your computer — ideal if you handle sensitive information. It's the default mode and is free forever with no account required.
Cloud Mode sends your requests to our cloud infrastructure for processing by powerful LLMs (like GPT-4 or Claude). It offers higher accuracy and more complex reasoning. It requires a Rexii account (Google sign-in) and an active Pro or Team plan.
Yes. In Privacy Mode, nothing leaves your device — zero network requests. In Cloud Mode, all data is encrypted in transit (TLS 1.3) and at rest (AES-256). We never sell, share, or use your data for training. See our Privacy Policy for full details.
No. In Privacy Mode, audio is processed in memory and immediately discarded — never saved to disk. In Cloud Mode, audio is streamed to our servers for transcription but is not stored after processing. We do not keep voice recordings.
Only when you explicitly activate screen context for a command. Screenshots are processed in memory to understand what app you're in and what's on screen, then immediately discarded. They are never stored or transmitted to our servers — even in Cloud Mode.
Privacy Mode is free forever — no account, no credit card, no usage limits. Cloud Mode features require a paid Pro ($9/month) or Team ($19/user/month) plan. A 14-day free trial is available for Pro.
Yes, you can cancel at any time in the app's settings under Account → Subscription. Your plan remains active until the end of the current billing period, and you won't be charged again.
Sign in with your Google account on each device. Your preferences, custom commands, and history sync automatically when you're on a Pro or Team plan.
We offer a full refund within the first 14 days of any paid plan. After that, you can cancel to stop future charges, but previous charges are non-refundable. Contact info@rexii.io for refund requests.
First, check that Rexii has microphone permission in your system settings (System Preferences → Privacy & Security → Microphone on Mac; Settings → Privacy → Microphone on Windows). Also verify you're using the correct hotkey (Right ⌥ on Mac, Right Ctrl on Windows). If issues persist, try a different microphone or restart Rexii.
Try speaking in complete sentences — Rexii's AI understands context better with full thoughts. Reduce background noise if possible, and make sure your microphone is positioned within 2 feet. In Cloud Mode, check your internet connection speed. You can also review the transcription in the Rexii history panel to spot patterns.
Make sure the app is in focus when you give the command. Some apps require accessibility permissions — check System Preferences → Privacy & Security → Accessibility on Mac. If the app isn't in our supported list, Rexii falls back to general dictation mode. Request new integrations at info@rexii.io.
Email us at info@rexii.io with a description of the issue, your OS version, Rexii version (found in Settings → About), and steps to reproduce. Screenshots or screen recordings are very helpful. You can also report bugs in our Discord community.
