Hello.

This blog post lists various web apps I've generated using Repl.it and WebSim, along with their code. Repl.it apps include tools like an image analyzer, time zone tracker, and a blood pressure tracker. WebSim creations include a 3D globe and gravity simulators. I discuss my preference for Postgres over sqlite, especially with Repl.it's tendency to overwrite sqlite databases upon deployment.

I explored using LLMs for checking web API browser compatibility. Existing LLMs struggle with outdated data, so I experimented with MDN's Browser Compat Data (BCD). Initial trials using raw BCD JSON with GPT-4 had limitations. To improve this, I converted the BCD into English descriptions of API support and loaded it into a Polymath instance. This allows natural language queries about API compatibility across browsers, like "Is CSS Grid supported in Safari, Firefox, and Chrome?" or "When was CSS acos available in Chrome?". The results are promising, but further refinement is needed to ensure accuracy and reliability.
