We built RightNow CLI because most coding AIs don’t understand GPUs. They can write Python, but not CUDA, they miss memory coalescing, warp divergence, register pressure, and all the details that make or break GPU performance. RightNow CLI changes that. It’s an AI-powered CLI that can actually reason about GPU architecture. It writes, debugs, and optimizes CUDA kernels natively, no setup, no MCP servers, no config. It’s open source, free to use, and connects seamlessly with the RightNow AI Code Editor, our GPU-native IDE https://www.rightnowai.co/ We’re proud to make GPU programming faster and more accessible for everyone.

Love seeing an AI that actually understands GPUs. The CLI plus GPU-native editor, with profiling, benchmarking and the emulator, is exactly what CUDA devs need. Open source is a big win. Curious how it handles warp divergence and register pressure in real code.
