Spectrum Sync - Tone Coach

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 your normal 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, it analyzes your words and offers friendly feedback:

• Green, yellow, or red tone status

• Short warnings when wording may land wrong

• Plain-language explanations of why

• Suggested rewrites you can tap to use



HOW IT WORKS

1. Complete quick in-app setup

2. Enable Spectrum Sync Coach in Android Accessibility settings

3. Open any supported messaging, social, or email app

4. Type as usual — a floating coaching overlay appears when you pause or finish a sentence



No replacement keyboard required. Spectrum Sync works alongside your existing keyboard in text and chat apps.
