Sobre esta extensión

LLM Chat Benchmark measures real user performance for AI chat apps like ChatGPT, Claude, Gemini, and Perplexity directly in the browser UI. It tracks time to first word, time to last word, stall/jitter, word count, and streaming speed, then shows results in a floating overlay and local dashboard with charts, model breakdowns, import/export, and raw-data inspection. All data stays local in this release; no remote telemetry is sent.
