- Does my voice or my text leave my Mac?
- No. Audio, transcripts, history and the AI cleanup pass all stay on your Mac. Rhino only reaches the network to check for signed app updates and to download speech models you explicitly ask for.
- Does Rhino work offline?
- Yes. Once you have downloaded a speech model, dictation and cleanup both work with the network off — on a plane, on hotel Wi-Fi you do not trust, or with the machine air-gapped.
- What are the system requirements?
- An Apple silicon Mac running macOS 14 or later. Intel Macs are not supported, because the on-device speech and cleanup models need Apple silicon to run fast enough to be worth using.
- Which apps does Rhino work with?
- Any Mac app that accepts text. Rhino inserts at your cursor wherever it happens to be — mail clients, browsers, editors, Slack, terminals. It needs Microphone and Accessibility permissions to do that.
- How is this different from Wispr Flow?
- Wispr Flow processes your speech in its cloud on a $15/month subscription and runs on Mac, Windows and mobile. Rhino Voice processes everything on your own Mac, works offline, costs $20 once, and is macOS-only.
- How is this different from the dictation built into macOS?
- Apple's dictation also runs on-device, so it solves the privacy question too. What it does not do is clean up how people speak — it transcribes you literally, ums and false starts included. Rhino Voice runs a local AI pass that turns what you said into the sentence you meant.
- Is there a free trial?
- There is a 30-day money-back guarantee instead. Buy it, use it properly, and if it has not earned its keep, email me and I will refund you.
- Can I delete my dictation history?
- Yes. History lives on your Mac. You can delete individual recordings, clear all of it, set a retention limit, or turn history off so nothing is stored in the first place.
