What it does
SweepSonar finds the Reddit, Quora, HN and Stack Exchange threads that already rank for what you sell, and scores which are worth answering. Your reply keeps working in search and AI answers for months. It drafts, you post. Free tier, no card.

Reddit and forum threads rank for years, and AI tools lean on them heavily when they answer questions. SweepSonar finds the threads that are already ranking for what you sell, so a reply you write today keeps working long after you post it. Everyone tries it for a few weeks. Here is where it falls apart. Search a keyword and you get hundreds of results. Only some of them rank, and only some of those are about a problem you solve. Sorting that by hand is the part that does not scale. A thread with 200 upvotes might get no search traffic at all. A quiet one might sit at position 2 for a term people search every month. Upvotes do not tell you which is which. You bookmark ten threads, reply to…from sweepsonar.com

Linkeddit2025 · linkeddit.com · ▲618The tool actually hit Product Hunt #1 back in February. Since then I’ve added a bunch more on top of the original version. Now you just describe the intent or goal for the leads you want, and it searches based on keywords and a bunch of other signals to surface the best ones for you. I also added a Reddit-powered content writer. Basically, you pick a topic or category, and it pulls the top posts from Reddit, analyzes what made them go viral, and helps you write content using the same patterns. Reddit is super underrated for content. If something blows up there, it almost always spreads to…
OverleadFeb 2026 · overlead.co · ▲146Here's the problem: I launched two products. I wrote blog posts. I posted on X, built in public. I tried running ads. And you know what actually got me customers? Replying to someone on Reddit who asked, "What's the best tool for this?" One reply. Three signups. I felt like an idiot for not doing it sooner. But here's the issue: I don't have time to refresh Reddit all day looking for these posts. I have products to build. Bugs to fix. Emails to answer. Life to live. So I built Overlead to do the searching for me. Overlead scans Reddit, Quora, and Hacker News (and many more to come) for…


CandySearch2025 · candysearch.vercel.app · ▲8Excited to share something I've been building recently called CandySearch. 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!

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
