Dust vs. Retell AI

Dust is the multiplayer AI platform for human-agent collaboration. People and agents work as co-contributors with shared context, knowledge, and tools, so that work doesn't just get done, it gets rewired. Dust gives teams shared workspaces, an intelligent context layer that synthesizes company knowledge across tools, and the flexibility to switch between models from OpenAI, Anthropic, Google, and Mistral. Trusted by 3,000+ organizations.
