What Hacker News says?
We’re RightNow AI. We built a tool that automatically profiles, detects bottlenecks, and generates optimized CUDA kernels using AI. If you’ve written CUDA before, you know how it goes. You spend hours tweaking memory access, digging through profiler dumps, swapping out intrinsics, and praying it’ll run faster. Most of the time, you're guessing. We got tired of it. So we built something that just works. What RightNow…

HN discussionRightNow CLI is now open source. It automatically optimizes CUDA kernels using AI. Depending on the kernel, it can achieve 10 to 50x speedups by removing bottlenecks and tuning for your GPU. How it works: - Analyze kernel patterns - Generate AI-optimized variants - Benchmark automatically - Ship the fastest version You can see and modify everything. Full control and transparency. Open source here: https://github.com…

HN discussionI built an AI dev tool that helps you write and optimize CUDA code just by chatting. No deep GPU knowledge, no stress! Just vibe with the AI and (hopefully) get better performance. Roast it here: https://www.rightnowai.co

HN discussionAfter a ton of feedback, I've pivoted RightNow AI into v2: a browser-based chat interface that helps you write high-performance CUDA code without touching NSight or spending hours profiling. Just tell it what you're trying to do, and it generates optimized CUDA kernels—sometimes outperforming NVIDIA’s own. We’re focusing heavily on real-time bottleneck profiling to keep things fast and smart. Try it out here: https:…

HN discussionTesting CUDA kernels on 15 different GPUs costs $3,000/month. We couldn't afford that!! So we built an emulator. give it your kernel code and it tells you exactly how it runs on any GPU. H100, A100, RTX 4090, V100, whatever "without running a single line" Not a rough estimate. Real numbers. 2.4ms on RTX 4090, 5.1ms on V100. Within 1% of actual hardware. How it works: We have three emulators. Each trades accuracy for…

HN discussionhey:D i built a tool that lets any dev write and optimize cuda code without knowing gpu stuff. just tell it what you want, it generates the kernel, runs it, and shows you bottlenecks. no setup, no cuda experience needed. we launched 3 days ago and hit #1 developer tool on product hunt. you can get started for free here: https://rightnowai.co would love your feedback if you try it out.

HN discussionHey everyone, I’m a solo founder and I launched RightNow AI ( https://www.rightnowai.co/ ) 3 days ago. It’s a tool for CUDA engineers (you write what you want, and it gives you optimized CUDA kernels + profiles them on serverless GPUs to find bottlenecks). No coding needed, works like a chat editor. We ranked #1 Developer Tool and #2 AI Tool on Product Hunt. If you’re a CUDA dev, I’d really love if you tried it (it’…

on a deleted threadHi HN, I am a solo founder building RightNow AI https://www.rightnowai.co/ , a tool that profiles, detects bottlenecks, and optimizes CUDA kernels using AI. The idea started from my own frustration with CUDA development. Profiling and optimizing kernels was slow, manual, and often required deep GPU expertise. I kept thinking there had to be a better way. I built RightNow AI alone. No co-founder. No early team. Every…

on a deleted threadOptimizing CUDA kernels is often complex and requires expert knowledge. So, I built a tool that simplifies this process by profiling your code on serverless GPUs (matched to your GPU architecture), identifying bottlenecks in your kernel code, and applying SOTA optimization techniques to deliver up to 20x faster performance—all without any manual tuning. DeepSeek’s R1 showed how optimizing kernels can significantly r…
