Perfetto2LLM

Perfetto2LLM is a web-based tool for visualizing and exporting Perfetto traces—system performance recordings from Chrome, Android, and custom sources—in formats optimized for large language models. Users can load traces, select specific kernels or time slices, and export the data as structured text, Markdown, or JSON to paste directly into LLM conversations. The maker built this tool to streamline the workflow of analyzing performance traces for ML and GPU optimization, eliminating the friction of manual copy-pasting from compressed files.

The application runs entirely in the browser, keeping trace data private and avoiding file uploads. It supports fast filtering and selection of trace sections, making it practical for engineers who frequently ask LLMs questions about system behavior and bottlenecks.
