RightNow CUDA Editor - AI code editor for GPU development

RightNow AI is the only AI code editor built specifically for CUDA. Features agentic AI that knows your GPU architecture, real Nsight Compute profiling inline, natural language to NCU commands, and 86+ GPU emulation with <2% error. Benchmark across block sizes, thread counts, and memory layouts. View PTX/SASS assembly side-by-side. Profile multiple GPUs simultaneously. Connect to remote GPUs or run fully local with offline LLM support. Supports all NVIDIA GPUs from GTX 1060 to H100.

GPU development shouldn't require switching between five tools just to understand why your kernel is slow.

RightNow AI is the first GPU-native code editor. It brings real-time profiling, a cycle-accurate emulator, and AI that actually understands CUDA all in one place.Profile without leaving your code. Emulate H100s without the hardware. Ask optimization questions in plain english.

Free to download. Give it a try, and join our Discord if you have feature requests :D

 how do you see this replacing the current multi‑tool workflow?

Now that's what I call a CUDA code editor :D

 exactly!!

💎 Pixel perfection

This is really a very great editor, packed with features. Also, the website is pretty cool. I really loved the text animations :)

 many thanks Chilarai:D

GPU dev is such a niche pain point, so it’s cool to see a tool built specifically for it. If the AI assistance actually understands CUDA context, this is going to save people hours of debugging.

GPU profiling + AI optimization in one editor? Game changer for ML engineers.

Can it benchmark different GPU architectures side by side?

Great niche solution. Congratulations on the launch!
