ReplyGain

Founders and solo makers who need customers often spend 2+ hours a day manually scrolling Reddit, X, Hacker News and Bluesky, jumping between feeds and saved searches to find people asking for a product like theirs. Even after opening dozens of posts, most of that time goes into sorting signal from noise, and then more time is spent researching each thread before writing a reply from scratch. The page states this costs founders time they can't afford while building, and that good-fit buyers slip past while they are busy with other work.

ReplyGain lets a founder enter their website URL, then uses AI to read the site and auto-generate keywords (direct-intent phrases, brand mentions, competitor names, category and pain terms) and a starter list of communities to monitor, which the user can review and edit. It then monitors Reddit, X, Hacker News and Bluesky around the clock, scoring every post by purchase intent and surfacing only high-intent leads in a ranked feed instead of thousands of raw mentions. For each lead, ReplyGain drafts a suggested reply that the user can regenerate, edit, and copy to post manually themselves, since the tool never posts on the user's behalf. Paid plans above the base tier also support custom prompt templates so replies match the user's own tone (helpful, direct, casual, etc.), and the company states replies get indexed and can rank in Google and AI search results over time.

The site frames urgency around speed to reply: "Right now, someone in your niche is asking for a tool like yours. Whoever replies first gets the customer."
