Description
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.
