All-in-one AI-powered code editor for CUDA with hardware-aware agents, GPU emulation/virtualization, real-time profiling and enterprise benchmarking.
Key features
Agentic Hardware-Aware Assistant: An AI agent that reasons about NVIDIA GPU architecture (memory hierarchy, warp scheduling, occupancy) to suggest kernel-level optimizations, launch configuration changes, and micro-architectural fixes tailored to the target GPU.
GPU Emulation and CPU Simulation Mode: Built-in GPU emulator allowing developers to run and test CUDA code on machines without physical GPUs by simulating GPU behavior and validating kernel logic before deployment.
GPU Virtualization Support: Virtualized GPU environments for remote testing and multi-tenant workflows, enabling developers to run GPU workloads in isolated virtual GPUs for reproducible experiments.
Real-time Profiling with Smart Terminal: Live profiling integrated into the editor that surfaces hotspots, stalls, memory transfers, and kernel timelines in the terminal while code runs, allowing rapid iterative tuning.
Line-by-Line Performance Analysis: Fine-grained cost annotations that attribute runtime and memory behavior to specific lines or blocks of CUDA code to pinpoint bottlenecks and inefficient constructs.
Benchmarking Terminal with Sweep Configurations: Enterprise-grade benchmarking tooling that runs parameter sweeps (grid/search) across kernel launch parameters, inputs, and device targets and produces reproducible reports.
Open-source CLI and Easy Install: Community-facing CLI (rightnow-cli) available via pip for quick setup, enabling a lightweight GPU-native AI code assistant and integration into developer workflows and CI.
GPU Profiler Visualization: Web-based visualization transforms NVIDIA profiling data into timeline views, flame graphs, heatmaps and includes AI-powered bottleneck detection to accelerate root-cause analysis.
