ColdMessageAI is a free, open-source Chrome extension that leverages ChatGPT to generate hyper-personalized cold messages for LinkedIn. By analyzing a prospect’s profile and your input, it creates tailored messages that are more likely to get replies. This tool saves time and effort in manual outreach, making it ideal for sales professionals, marketers, and networkers. Note: As of October 2023, the extension no longer works due to changes in ChatGPT’s API.
