Cortex: Compare AI Chat Models

Your all-in-one AI assistant. Chat with leading AI models in one app: OpenAI GPT, Anthropic Claude, Google Gemini, xAI Grok, DeepSeek, Mistral and more, through each provider's official API. Ask once, compare answers side by side, and keep the best one. Cortex is free to download. All models and the features below (side-by-side compare, live web search, scheduled prompts, smart memory, voice, file uploads and image generation) require a Cortex Pro subscription.
