Claude Code for CUDA, an open-source AI CLI for GPU devs
Claude Code for CUDA. Free AI assistant that actually understands GPU architecture, write, debug, and optimize GPU kernels right from your terminal. Built by RightNow AI, the first GPU-native AI code editor.
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.
