SAiY is an AI keyboard for iOS, Android, Mac, Windows and browsers that writes, edits, translates and adjusts the tone of your messages inside any app where you already type.
Draft, rewrite, fix grammar and adjust the tone of messages in seconds, directly inside any app where you type.
Translate between 50+ languages while you type, so you can reply to international customers fluently.
One tap switches between professional, friendly, persuasive or apologetic tones, keeping your message appropriate for the context.
Generate social posts, ad headlines and email copy in your brand voice without leaving the keyboard.

Typeahead is a system-wide AI autocomplete app for Mac that completes your sentences inside the apps you already use, running entirely on your machine so your writing is never sent to a server.
Faint ghost text completes the word or sentence you are typing right at the cursor. Tab accepts the entire suggestion, the right arrow takes just the next word, and Esc dismisses it so you stay in control.
The model runs on your Mac rather than in the cloud. Typeahead never sends your writing to a server and keeps working offline after setup, which makes it suitable for work email and sensitive documents.
It reads what is on screen and what you copied to the clipboard, so replies fit the thread you are actually answering rather than being generic filler.
Set a voice per app, professional in Mail and friendly in Messages, choose from seven color-blind-safe highlight shades, and tune suggestion timing to instant, balanced or only when you pause.

免費 / 開源GHOSTYPE is a macOS voice input layer that replaces typing with speech and then cleans the result with AI. You hold a hotkey, talk naturally, and polished text lands directly in whatever app has focus — email, chat, code editor or notes — with per-app tone profiles so a Slack message and a client email do not sound the same.
