Gorilla vs ReplyGuy.
ReplyGuy is an AI auto-reply tool for Reddit, X and Hacker News. It posts replies that mention your product on threads matching your keywords. Gorilla finds the threads, ranks them by buying intent across 4 platforms, and gives you the URL so you reply yourself for $0.99 a run. We mean the brand ReplyGuy, not the social-media slang.
The 30-second answer
Pick ReplyGuy if you want set-it-and-forget-it auto-replies and you accept the account risk. Pick Gorilla if you want to find the highest-intent threads across Reddit, X, YouTube and TikTok and reply yourself, like a human.

When each tool wins
ReplyGuy is better when
You want hands-off engagement and you've accepted that an account could get flagged. Hacker News is a key channel for you. You already have an established brand voice the AI can copy without sounding off.
Gorilla is better when
You're early. You want to read the room before you reply. You want to compare signal across Reddit, X, YouTube and TikTok in one shot. You'd rather pay per run than carry another monthly subscription.
The auto-reply problem
Reddit, X and HN all have spam-detection systems built around posting patterns. New account, replies fast, mentions a product, posts often, links the same domain. That fingerprint gets accounts shadowbanned all the time. Auto-reply tools don't always trip it, but when they do, you don't get a warning. The account just stops mattering. Comments still appear to you and rank zero for everyone else.
Reddit moderators are the second filter. Most product subs ban self-promotion outright. A few allow it under a 9:1 rule (nine helpful comments for every one promotional). An AI replying to keyword matches will not pass that ratio, ever. Your account gets removed from the sub and your domain often joins the auto-block list. That damage carries across every account on your IP.
Manual replies dodge that. A founder who reads the thread, agrees with one part, pushes back on another, and mentions their tool once at the bottom looks like a person. Because they are. Conversion on those replies is also higher. People reply to people, not to templates. Founders who comment from a real account with a posting history convert leads at multiples of any auto-reply benchmark we've seen reported.
Gorilla is built around that workflow. We surface the thread, score it for intent, and stop. The reply is yours. Your account, your voice, your judgement on whether this thread is worth a comment at all.
The 4-platform argument
ReplyGuy covers Reddit, X and Hacker News. Gorilla covers Reddit, X, YouTube and TikTok. If your audience watches creators or scrolls short-form video, the YouTube and TikTok comment threads under "I'm looking for a tool that does X" videos are some of the highest-intent leads on the internet. ReplyGuy doesn't see them. Gorilla pulls all four in parallel and shows which platform has the most demand for your specific idea.
YouTube comments in particular tend to be slept on. A creator reviews a competitor, viewers in the comments ask "is there a cheaper version?", and most founders never see those threads because they're buried under a video. Gorilla pulls them up by intent score and lets you reply to a person who has already raised their hand.
To be fair: ReplyGuy has Hacker News. We don't. If HN is your channel, that's a real gap on our side. We may add it later. We have not.
Pricing math
ReplyGuy runs on a monthly subscription, roughly fifty to a hundred dollars depending on plan. Gorilla is $0.99 per run, or $2.99 a week on Pro for unlimited runs. If you run Gorilla once a week to refresh your lead list, you spend under five dollars a month. The savings only matter if your reply workflow is manual anyway, which most founders' should be in the first six months.
Why we don't auto-reply
We could ship auto-reply in a sprint. We won't. The tool that helps you find your first 100 users shouldn't also be the tool that gets your account banned. Once you have a brand, hire an SDR or run ReplyGuy. Until then, the highest-impact thing a founder can do is read 20 threads a day and reply to the 3 that matter.
