NEW: Voice Rehearsal — practice your delivery before real meetings. Every analysis runs on-device. No cloud. No tracking. Your text never leaves your iPhone.

ClearSpeak is an AI tone coach for non-native English speakers.

Paste any email, Slack message, or LinkedIn post — get instant tone scores, culture flags, and 3 AI rewrites in seconds. 100% on-device. Your text never leaves your iPhone.

CULTURE FLAGS — CATCH MISTAKES BEFORE YOU SEND

Phrases that sound perfectly fine in your native language can confuse or offend Americans. ClearSpeak catches them before you hit send:

• "Please do the needful" → "Could you handle this?" • "I am attaching herewith" → "I've attached..." • "Kindly revert at the earliest" → "Please let me know when you can"

Each flag is rated by severity (High / Medium / Low) so you know what to fix first.

TONE ANALYSIS — KNOW HOW YOU SOUND

Get a detailed score across 5 critical dimensions: • Formal — Are you matching the expected tone? • Confident — Do you sound sure of yourself? • Friendly — Are you building rapport? • Direct — Is your point clear? • Polite — Are you maintaining courtesy?

Each dimension comes with specific, actionable feedback.

VOICE REHEARSAL — PRACTICE YOUR DELIVERY

Record yourself speaking and get real-time feedback on: • Speaking pace (words per minute) • Filler word detection ("um", "uh", "like") • Confidence rating • Personalized improvement tips

Perfect for preparing presentations, interviews, and important calls.

3 AI REWRITE STYLES — SAY IT BETTER, INSTANTLY

Every analysis includes up to 3 alternative versions of your text: • Concise — Cut the fluff. Get to the point. • Diplomatic — Soften the tone without losing meaning. • Confident — Remove hedge words. Lead with clarity.
