What is T3.Chat?
T3.Chat is a fast, well-designed AI chat interface that supports custom OpenAI-compatible providers. It focuses on performance and a clean user experience, with features like conversation history, model switching, and markdown rendering. With 159 million tokens and 13,000 requests on OpenRouter, it has built a following among users who want a lightweight, high-quality chat interface.
T3.Chat supports adding custom API providers, which means you can point it at EUrouter with a few settings changes. Set the API base URL and key, choose a model, and your conversations go through EU servers. The chat experience stays the same while your data stays in Europe.
