Write with confidence. Spectrum Sync is your AI social language coach for text messaging, chat, SMS, and email.
Worried your text sounds too blunt, too intense, or easy to misunderstand? Spectrum Sync gives you real-time tone coaching while you type — using the Spectrum Sync Keyboard in the apps you already use.
Built for neurodivergent users and anyone who wants clearer, kinder digital communication, Spectrum Sync helps you catch tone problems before you send.
WHAT SPECTRUM SYNC DOES
Spectrum Sync is an AI text coach and social communication helper. As you compose messages with the Spectrum Sync Keyboard, it coaches the sentence you're writing and offers friendly feedback:
• A yellow or red pill when your wording may land wrong (nothing pops up when it looks fine)
• A short warning on the pill
• Plain-language explanations of why
• Suggested rewrites you can tap to use
HOW IT WORKS
1. Complete quick in-app setup and accept the coaching disclosure
2. Add Spectrum Sync Keyboard in iOS Settings → General → Keyboard → Keyboards
3. Turn on Allow Full Access (required for AI coaching; it lets the keyboard reach cloud AI when Apple Intelligence isn't available)
4. In Messages or another app, switch to Spectrum Sync with the globe key
5. Type a sentence and pause, or end with . ! ? — if the AI spots something, a coaching pill appears above the keyboard
Not sure it's working? Setup includes a "Try it now" practice box.

IMPORTANT
Spectrum Sync uses a custom keyboard extension. Allow Full Access is required for AI coaching. It lets the keyboard reach cloud AI when on-device Apple Intelligence isn't available. It is never used for ads. Only the sentence being coached, plus a few recent sentences for context, is sent for cloud coaching, and secure/password fields are skipped. You will be guided through setup and disclosure before enabling it.
