ReplyGuy – AI Reddit auto replies for lead gen and brand protection▲7
Excited to share something I've been building recently called ReplyGuy. I made it to solve a personal pain with a SaaS product I built, which was that we were always monitoring Reddit and Twitter to see if anyone had mentioned keywords indicating they were looking for us. Before, we had to go manually respond to posts, often missing good mention opportunities. Would love for HN folks to try it and let me know what you think!

Replyt▲10
I kept finding Reddit threads where people were discussing problems my products solved, usually weeks after the discussion happened. Even when I joined those conversations, I had no idea whether they led to anything. A signup? A paying customer? Nothing? So I built Replyt. Replyt continuously watches Reddit for discussions related to a product, surfaces relevant conversations, and helps engage through public replies or contextual DMs. What became interesting was not finding the conversations, but measuring them. Replyt tracks visits, signups, and paying customers back to the Reddit…
