On a flight, on the train, or somewhere with a patchy connection, SuperSpeller keeps helping you find your words in supported Mac apps.

Your writing help works offline
Autocomplete, predictive text, and spelling suggestions run on your Mac. The AI model comes with the app, so once you've downloaded SuperSpeller, there's no separate model download or online setup to start your free trial.
Your words stay on your device
Your writing and suggestions never go to a cloud AI service. Processing stays local whether you're connected to the internet or working offline.
Try it without signing up
The 7-day free trial needs no account or internet connection after downloading the app. Try it in the places you write, including when you're offline.

When you need an internet connection

Paid licenses need internet access for activation and periodic verification. After a successful license check, you can work offline for up to 30 days. Reconnect before that period ends to keep using your paid license.

Downloading SuperSpeller and software updates also use the internet. License checks do not send your writing, and your AI suggestions continue to run on your Mac.

Find a comfortable way to write

Start with the predictive text setup guide, read about writing offline, or explore writing support for dyslexia.

Try SuperSpeller in your everyday writing for 7 days. If it suits you, a license costs US$15.99 once.
