Gerty is a private AI assistant that runs open language models directly on your Mac with no cloud connection, account or subscription required.
About Gerty
Gerty is a private AI assistant that runs entirely on your Mac using open language models on its own chip. It can chat, write, answer questions from your documents and scans, integrate with Mail and Calendar, and respond with voice from the notch—all without sending any data to the cloud or requiring an account.
Unlike typical AI assistants that send your data to remote servers, Gerty keeps everything on your Mac and works completely offline once models are downloaded. It automatically selects and sets up the best-performing models for your specific Mac, with no configuration needed.
Gerty is a one-time purchase for CHF 49 with no subscription, no usage limits, and free updates to all future versions. One licence works on up to three of your own Macs simultaneously.

FAQ
- What is Gerty?
- Gerty is a private AI assistant for the Mac that runs open language models on your Mac's own chip. It can chat, write, find answers in your documents including scans, work with Mail, Calendar and other apps, and answer aloud from the notch, without sending any data to the cloud.
- Is Gerty a ChatGPT alternative?
- Yes, Gerty works for everything you would use a chat assistant for day to day, with the key difference that the model runs on your Mac itself: no account, no subscription, and it works offline.
- Can I use Gerty with confidential or personal data?
- Yes, that is what Gerty is made for. Nothing you write leaves the Mac, so there is no data processor, no transfer abroad and no third party, which addresses most GDPR and professional-secrecy concerns.
- Does Gerty need an account?
- No. You never sign in. You enter your licence key once on each Mac and Gerty activates and runs offline. One key works on 3 Macs at a time, and you can move it to a new Mac whenever you like.
- Does Gerty work offline?
- Yes. Once a model is downloaded, chat, files, voice, memory and Mac apps all work without internet. Only web search, model downloads, update checks and connectors you switch on use the network.
