Your words process on your Mac. Nowhere else.
Typeahead is AI writing assistance that runs entirely on your device. There is no server receiving your text, no account storing your history, no cloud model processing your drafts.
Most AI tools promise to protect your data.
Typeahead was never built to collect it.
How other tools work
Your text goes to a server. They make a policy commitment about how they use it. Policies can change. Servers can be breached. Terms can be updated.
How Typeahead works
Your text is processed by a model on your Mac and discarded after the suggestion. Your writing never touches a server. Nothing to breach, because there is no transmission.
How It Works
Architectural privacy means specific, verifiable things.
Processing stays local
Typeahead's AI model is downloaded once during installation and runs on your Mac. Suggestions are generated on your device, not fetched from a server.
Offline after install
After the initial download, Typeahead never needs an internet connection. Use it on a plane, in airplane mode, disconnected from your network entirely.
Account-free
Typeahead has no user account, no login, no profile. There is nothing to associate your typing with an identity.
Session data is discarded
Typeahead uses the text immediately around your cursor to generate a suggestion. It doesn't build a history. There is no persistent storage of your writing.
License verified locally
Your purchase is verified on your device at install. Typeahead doesn't ping a server every time you launch it.
Verifiable independently
Disconnect from the internet and use Typeahead normally. It works identically. The only network activity you'll ever see is license activation and optional update checks.
Who It’s For
Privacy isn’t a feature for a specific type of person.
It’s for anyone who types things they care about.
Lawyers drafting client communications
Founders writing strategic memos
Therapists recording session notes
Journalists protecting source conversations
Researchers with pre-publication data
Anyone who doesn't want their writing indexed by a third party

Privacy
Your questions, answered technically.
Disconnect from the internet and use Typeahead normally. It works identically. Run a network monitor like Little Snitch or Wireshark while typing. You'll see no connections related to your writing. The only network activity is license activation and optional update checks.
Typeahead reads the text immediately around your cursor in the active text field to generate a suggestion. It does not access other documents, windows, or your file system. Suggestions are generated and discarded immediately.
The model runs entirely on your Mac. There is no telemetry, no usage reporting, no analytics. The only network activity is license verification at install time and optional update checks.
Typeahead does not transmit, store, or process data outside your device. Because there is no data transmission, the third-party processing concerns raised by most compliance frameworks don't apply. Consult your compliance team for your specific situation.
Typeahead continues to work. The AI model lives on your Mac. There is no server dependency for the core product. Your license and the app function independently.
One-time purchase. $79. Own it permanently.
Privacy you can verify, not just trust.
The model runs locally, your text processes on your device, and nothing is transmitted. Ever. That's not a promise — it's how it's built.
Processes locally. Works offline. Account-free. One-time purchase.
