Chat with the Best AI Models in One Place
Chat to all the best AI models in one place
In plain English
People who want to chat with many of the best-known AIs from a single website can use Multex, from Tom Builds. One monthly subscription covers that chat, with a limit on how much you can use. They pay because keeping several paid AI chats going at once is a hassle. New users arrive through search, comparison pages, and word of mouth. The AI does most of the answering and the billing, while Tom checks quality, helps users, and handles unusual cases.
