Show HN: Perfetto2LLM - A tool to pass system traces to an LLM I work with perfetto traces for ML/GPU optimization a lot. Copy pasting trace info to LLM is not easy. As usually the traces are gzip compressed, have very large file sizes. Also there is no way to select a certain section and sending it to LLM easily (can maybe write a query to do this but not ergonomic). So vibe coded this tool to quickly select the kernels/slices/threads I want to ask about and one click to get a text/json/markdown in my clipboard to paste for LLMs. I think an MCP server for this might also be useful (tried a few but all miss certain things i wanted so chose to just build this quickly) https://perfetto-to-llm.vercel.app/ December 31, 2025 at 02:38AM
