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.
