Google vs. Perplexity Chrome Extension (github.com)

I was always switching between Google AI and Perplexity for medical or important questions since these two give me links to verify. And I checked them against each other i.e. LLM as a judge, but with links to be sure.

So I built a chrome plugin to talk to both at once and verify each other's messages.

Is it provider specific? Can I easily switch providers?
