nCompass

nCompass is the first AI coding assistant that reasons with runtime profiling data, enabling engineers to write performant code—not just correct code. It unifies profiling, trace viewing, and trace analysis into a single IDE interface, eliminating the need to context-switch between fragmented tools. The nCompass agent pairs with Cursor and Claude Code to automatically diagnose performance bottlenecks, cutting weeks off optimization cycles. Trusted by engineers at Snowflake, RedHat, and vLLM, and backed by Y Combinator and Amino Capital.

• Runtime Profiling Integration: Run ncu, perf, nsys, torch profiler, and more directly from the IDE without leaving your coding environment.
• Trace Viewer: Inspect execution traces, flamegraphs, and performance timelines inline within VSCode, Cursor, or Claude Code.
• TraceDiff: Compare two traces side-by-side to identify regressions or improvements across code changes.
• Bottleneck Finder: Automatically surface CPU syncs, memory leaks, bad multi-threading, and underutilized GPU kernels with actionable suggestions.
• AI Agent Integration: Pair the nCompass agent with Cursor or Claude Code to automate root-cause analysis and receive optimization recommendations.
• Kernel Analyzer: Perform advanced GPU kernel analysis with group creation and trace-wide statistics.
• No-Code Profile Markers: Add custom profiling regions to your code without manual edits.
• Team Collaboration: Share and collaborate on trace files with teammates directly inside the IDE.
• Full Manual Control: Every tool available to the AI agent is also accessible to the developer—automate as much or as little as desired.
