How We Reduced LLM Latency by 89% and Token Usage by 91% in a Production Chrome Extension

Introduction When building our AI-powered bookmark organizer, Simmark, our primary goal was to eliminate user friction. Unlike other tools, we bypass the need for users to manually generate and input API keys by handling the LLM integration directly through our backend environment. However, our initial implementation was heavily unoptimized. Processing 200 bookmarks took an average of 62.74 seconds. This latency was unacceptable for a seamless user experience.
