TypingMind is a chat UI layer that sits in front of your own API keys, giving you a single organized interface across OpenAI, Anthropic, Google, and other providers. You bring the keys, you pay the providers directly, and TypingMind handles the interface: folders, search, tagging, multi-model parallel responses, document uploads, and a prompt library. The self-hosted path lets teams run the whole thing on private infrastructure. The ceiling appears when you need agents that actually run tasks without your input — TypingMind is a UI, not an execution engine, so every action still requires you to drive.
