What does this tool do?
Convosify is a privacy-focused AI conversation assistant for macOS that specializes in real-time toxicity detection and message enhancement. Its core feature, Message Guardian, uses on-device machine learning to analyze messages in Slack and other applications before they're sent, detecting potentially problematic language like hostility, toxicity, or unprofessional tone. Unlike cloud-based tools, Convosify processes everything locally on the user's Mac, ensuring complete privacy and offline functionality.
