What exactly is a LinkedIn smart commenting tool?
A LinkedIn smart commenting tool is an automation software that uses artificial intelligence to create, suggest, or automatically post comments on LinkedIn content. It scans targeted posts based on keywords, creators, or industries, then crafts personalized, human-sounding replies to foster engagement. For instance, tools like Commenter AI read a post and generate thoughtful comments that align with your brand voice, turning passive scrolling into active networking.
