What is ColdMessageAI for LinkedIn
GPT Written LinkedIn messages [Oct 2023 Update: The extension no longer works. ChatGPT has changed its API and added Arkose Captcha. and the app failed to gain traction so we've decided not to update in further.]
ColdMessageAI is a Completely Free OpenSource Cold Message writer which harnesses the power of ChatGPT to write hyper-personalized messages. It takes info from LinkedIn profiles and your prompt to create a personalized message for a specific person.
Personalized messages are more likely to get replies than a cookie cutter ones. But hand-writing them is tiring, so we've used ChatGPT to automate it.
