Multi-model AI chat platform that lets users bring encrypted API keys for GPT, Claude, Gemini, Grok, OpenRouter, and custom endpoints.

MultimodelChat (formerly Mykey AI Chat) is a multi-model chat workspace for using major AI providers from one interface while paying providers directly for usage. Users connect their own API keys for OpenAI, Anthropic, Google, xAI, OpenRouter, or custom OpenAI-compatible endpoints, with keys encrypted and decrypted server-side only when requests are sent to the selected provider. The service charges a flat platform subscription after a free trial and includes model switching, conversation history, file uploads, and limited web search without token markups.
