Langkast brings your AI work into one place. Use leading models from OpenAI, Anthropic, Google, xAI, DeepSeek and more without jumping between apps. Switch models in the same conversation, organize chats into projects, work with your files, save and reuse prompts, and build agents for repetitive work. Instead of managing separate AI subscriptions, conversations and workflows, Langkast gives you one workspace to get things done with AI.
