Lessons learned from being customer zero of Chrome's built-in APIs
summary
Builds a local AI synonym finder using Gemini Nano and the Prompt API Playground and shows it works as an MVP but needs heavy prompt engineering to avoid duplicate tokens and leading spaces and to enforce unique items by resetting the session. Uses prompt streaming to get tokens early instead of waiting for JSON and sanitizes outputs by stripping non ASCII before using innerHTML. Replaces repeated innerHTML writes with document.write into a createHTMLDocument to cut repaint churn and improve performance.
