What it does
I built BuildSignal to solve a problem every founder faces: finding people who actually need what you're building. BuildSignal finds real conversations across communities where people are already talking about problems, then uses AI to identify the strongest signals based on pain, intent, and ICP fit. No random lead lists. No guessing. Just real people with real problems. Find the pain. Find the people. Build what they need.
BuildSignal scans public conversations for real pain and buying intent, scores each signal, and turns them into a prioritized lead board for early-stage founders.
BuildSignal listens to real conversations across communities, finds high-intent pain signals, and turns them into a friendly list of people you can actually talk to. Find your first 25 customers from conversations already happening. 💬 No giant lead database. No random cold outreach. Just real people expressing real problems. They're posting on Reddit. Asking communities for recommendations. Describing frustrating workarounds. They're saying: Most founders never find these conversations. Or they spend hours searching manually, open 20 tabs, save a few links, and lose everything three days later. BuildSignal turns those scattered conversations into a friendly customer discovery pipeline. ✨…from buildsignal.lol

BrainGridMar 2026 · braingrid.ai · ▲26Hi HN, I’m Nico, one of the co-founders of BrainGrid. We built this after spending the last year building software almost entirely with AI coding tools like Claude Code and Cursor. Writing code was fast. Finishing anything reliably was not. Coding was not the bottleneck. planning was. It was everything before the code: unclear scope, missing edge cases, poor sequencing, and vague intent. Once a project went beyond a single prompt, small changes started breaking unrelated parts of the app. In traditional teams, product managers and tech leads handle this. I was a Director of Product at Twilio…

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…
