Question: I'm looking for a way to automate responding to YouTube comments with personalized messages.

If you want to automate YouTube comment responses with a more personal touch, Orange AI stands out as a useful tool. It lets content creators quickly analyze their audience's likes and dislikes and feedback, spot trends, and then automate their own replies with a more personal touch. The tool can help creators streamline audience engagement and create more effective content by freeing up time and helping them understand their audience better.

Another tool worth considering is ReplyMind, an AI-powered social media engagement tool that suggests personalized replies. It works on several social media services and offers a range of pricing plans, so it's a good option for content creators who want to expand their social presence through more engaging and relevant interactions.

You could also look at Chatfuel, a service that lets you create AI chatbots for several services to better engage customers and push sales. Although its main use is marketing and sales, it can handle an unlimited number of messages and respond with personalized answers, so it's worth considering for YouTube comment automation.
