Compatible with the Mac apps you write in.

Mac apps with a standard text field, including the browsers, email, document and chat apps on this page. Google Docs and Arc need a one-time setting. Terminals and code editors are off until you turn them on per app, and password managers and finance apps stay off by design.

Often, yes. Typeahead uses the macOS Accessibility API, the same one screen readers use, so most Mac apps with a standard text field work even if they aren't listed. Try it; the 30-day money-back guarantee covers you.

No. Typeahead works at the system level, so suggestions appear in Safari, Chrome, Firefox and the other browsers listed here without installing anything per browser. Arc needs a one-time setup step, marked on its entry above.

Sidebar chats and extension panels in editors work out of the box. The code buffer and the shell are off by default, partly so suggestions never surprise you there and partly because editors have their own completion systems. Enable them per app in Settings; in a terminal, Option-Return accepts a suggestion.

By design. Password managers, crypto wallets, and finance apps are off by default so suggestions never appear near credentials or financial data. Password fields are always off, wherever they are.

macOS only lets assistive software see text fields that apps expose through the Accessibility API. A few apps draw their own text and expose nothing, and virtual machines and remote desktops show the remote screen as pixels, so there's no text field to read. When the cursor's position is unreliable, Typeahead shows its suggestion in a small floating bubble instead of inline.

We recommend it, so Typeahead's suggestion is the only one at your cursor. Switch off the Mac's inline predictive text in System Settings › Keyboard (Edit next to Input Sources), and if you write in Gmail, turn off Smart Compose in Gmail's Settings › General.
