RouteGPT

RouteGPT is a Chrome extension for chatgpt.com that automatically selects the right OpenAI model for your prompt based on preferences you define. Instead of switching models manually, RouteGPT handles it for you — like automatic transmission for your ChatGPT experience.

For example:
“creative novel writing, story ideas, imaginative prose” → GPT-4o
“critical analysis, deep insights, and market research ” → o3

🔒 Requires ChatGPT Plus and a quick local install (see below)
