Vibecheck

VibeCheck is an AI-powered Chrome extension that analyzes the tone and emotion of your emails and messages on Gmail and LinkedIn – before you hit send.

What VibeCheck does for you:
• Shows real-time sentiment (positive / neutral / negative) for every conversation
• Detects emotions like confidence, hesitation, frustration, excitement and more
• Highlights risky or tense messages so you can rephrase before replying
• Gives simple, numeric scores and labels so teams can align on “how the message feels”
• Works on both Gmail and LinkedIn messages without changing your existing workflow

Perfect for:
• Sales, founders and BD teams who don’t want to lose deals to “tone misunderstandings”
• Support and success teams who need to catch angry or upset customers quickly
• Professionals who want their emails to sound clear, confident and empathetic

Privacy-first:
• All analysis runs locally in your browser
• No message content is sent to any external server
• No tracking, no analytics, no data collection
