RightNow CUDA Editor

RightNow CUDA Editor

AI code editor for GPU development

Website rightnowai.co
Overview

What it is

RightNow AI is the #1 GPU AI code editor. It combines GPU profiling, benchmarking, AI optimization, GPU virtualization, and a full GPU emulator in one environment to help developers analyze and optimize CUDA code faster

Intent

I need it when

Profile GPU kernel performance and identify bottlenecks in real-time

Integrated profiler with NCU integration, kernel benchmarking, config comparison, and bottleneck detection provides immediate performance insights without leaving the editor

Compare kernel performance across multiple GPU architectures and configurations

Multi-GPU performance comparison (up to 6 GPUs in Pro tier, unlimited in Forge) with stable SSH remote access enables cross-architecture optimization and scaling analysis

Analyze low-level kernel behavior through PTX and SASS inspection

Code analysis features provide PTX disassembly, SASS inspection, register pressure analysis, and race detection for deep performance debugging and correctness verification

Develop and optimize CUDA kernels without owning physical GPU hardware

GPU Emulator feature simulates 86+ NVIDIA GPU architectures with full CUDA API simulation and cycle-accurate execution, enabling kernel development and testing on any machine

Write CUDA kernels faster with AI-assisted code generation and optimization

AI chat assistant with GPU-aware suggestions, custom agents, and one-click optimization generates and refines kernels; supports local LLMs (Ollama, vLLM) or cloud providers via OpenRouter

Drop

Not a fit when

  • User develops on AMD or non-NVIDIA GPUs; product supports only NVIDIA CUDA GPUs
  • User requires on-premise deployment without enterprise Forge contract; only Forge tier offers on-premise options
  • User needs CI/CD pipeline integration; feature marked as 'Coming Soon' in documentation
  • User works with edge inference on resource-constrained devices; RightNow Editor targets datacenter GPU development, not edge optimization
  • User requires NVLink-aware load balancing; feature marked as 'Soon' and not yet available
  • User cannot install NVIDIA CUDA Toolkit 11.0+; this is a hard system requirement
