Replyze (ReplyGuy)

ReplyGuy takes a different approach to social selling than a simple reply generator. You create a project, add keywords related to what you sell, and the platform tracks mentions of those keywords across the web. Its AI then selects recent, high-quality, relevant posts where a reply could genuinely help — and drafts responses that mention your product only when it is a natural fit.

The pitch is time saved at scale. Manual prospecting means monitoring each network for hours, reading every mention, and writing tailored text for each one, which the site estimates at one to two hours per day per project. With ReplyGuy you set keywords once and it works continuously, which the team frames as saving tens of hours a month and bringing in new customers while you focus elsewhere.

It currently supports X (Twitter) and Reddit, with LinkedIn, TikTok, Hacker News, and other networks in progress. Pricing is credit-based with tiers from a free plan up through Small, Pro, Business, Enterprise, and Agency, and features include auto-replies, sentiment analysis, notifications, and reporting. Note: the site nowadays also promotes a text-to-speech converter, so it now bundles more than reply generation.
