RightNow CLI

Claude Code for CUDA, an open-source AI CLI for GPU devs

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

Develop and optimize CUDA kernels without owning multiple GPU hardware

RightNow Editor provides GPU emulator access (50+ GPU architectures) and multi-GPU comparison capabilities, allowing developers to test kernels on A100, H100, and other GPUs without physical hardware ownership

Profile and benchmark GPU kernel performance in real-time during development

The editor integrates NCU profiling, automated benchmarking, CodeLens performance metrics, and bottleneck detection, enabling developers to identify performance issues and optimize kernels without leaving the IDE

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

RightNow Editor offers AI autocomplete, GPU-optimized suggestions, natural language profiling, and one-click kernel optimization powered by local or cloud LLMs, reducing manual coding time

Analyze low-level GPU code execution and identify hardware bottlenecks

The editor provides PTX disassembly, SASS inspection, register pressure analysis, and race detection, giving developers deep insights into kernel behavior at the assembly level

Scale kernel development across multiple GPUs and compare performance

RightNow Editor supports multi-GPU performance comparison (up to 6 GPUs in Pro tier), stable SSH remote access, and multi-GPU execution analysis, enabling teams to optimize for distributed GPU environments

Drop

Not a fit when

  • User develops on AMD or non-NVIDIA GPUs, as the editor supports only NVIDIA CUDA GPUs
  • User requires on-premise deployment without enterprise Forge contract, which is enterprise-only
  • User needs multi-GPU execution analysis, which is listed as coming soon and not yet available
  • User works with edge inference on memory-constrained devices without separate PicoLM runtime
  • User requires CI/CD pipeline integration, which is marked as coming soon
