Chorus: Compare LLMs

rishicomplex

Chorus lets you start conversations with the top LLM chatbots directly from your browser's address bar. Type "ch <space>" into the address bar, write your message once, and have ChatGPT, Claude, DeepSeek and Gemini each open in their own tabs. This can be useful if you're looking to ensemble the responses of various LLMs, eg on a query like "give me gift ideas...", or if you're looking to compare the responses of top LLMs. Since it uses the native browser UI for each chatbot (rather than making API calls), you can use all the custom UI affordances these chatbots offer like code extensions and conversation links. This also lets you use your existing subscriptions rather than being charged for API access. Currently supports Claude, ChatGPT, Gemini and DeepSeek. Also supports some search engines like Google and Perplexity. You will need to be logged in to each chatbot's website on your browser to use your existing subscriptions.
