What is T3 Chat?
T3 Chat is a fast multi-model AI chat app that lets you switch between GPT, Claude, Gemini and other models in one interface, for power users. It is built by T3 Tools, the company of developer and YouTuber Theo Browne, who launched it in early 2025 after building a faster alternative to existing chat apps. Instead of paying for several separate AI subscriptions, users get many frontier and open models behind one low monthly price.
T3 Chat focuses on speed and workflow details. Responses stream quickly, chats can be branched to explore a different answer without losing the original, and you can switch model mid-conversation. It supports web search, file and image attachments, image generation and keyboard shortcuts. Developers, writers and students use it to compare model answers, code, research and draft text without juggling tabs.
