Question: I'm looking for a solution that automates finding and posting follow-up comments on social media to generate leads and promote my product.

One is ReplyGuy, an AI-powered system that finds and responds to social media posts about your product on Twitter and Reddit. It monitors keywords, picks posts and generates custom responses designed to help the person posting the message while also promoting your product. The service also offers sentiment analysis and 24/7 live chat support so you can assess response quality and respond to problems. The service has several pricing levels, from a free plan to a $499/month plan, so it should be adaptable to different business needs.

Another serious contender is Devi. The service monitors and responds to leads on several social media sites, including Facebook, LinkedIn, Twitter and Reddit, using AI to identify high-intent leads and generate custom comments. It also can create visual content and send real-time webhook notifications for new leads. Devi is designed to automate social media monitoring and engagement so businesses can free up time to focus on converting leads. Pricing starts at $19 per month, with a yearly plan option, and a 10-day free trial.

For a more basic, AI-driven commenting experience, Replai offers a Chrome extension that can write comments on Twitter and LinkedIn with a click. It can be used to build relationships and promote products by setting up automated personalized comments. It's designed to increase visibility and save up to 32 hours a month, making it a good option for salespeople, business owners and marketers.

Last, you could look at Sparksocial, an engagement and lead generation service that uses AI to amplify your social media presence on sites like Reddit, Twitter, LinkedIn and Facebook. It includes features like automated engagement, auto-generated replies, competitive analysis and audience discovery. With several pricing levels and a 7-day free trial, Sparksocial could help you reach new customers and expand your social media presence.
