Your models.
One workspace.
A focused place to chat, research, and work with files—without bouncing between AI apps.
Pick the model that fits.
Move between models in one conversation, and bring in documents or web search when the task needs more context. The picker shows what’s currently available.
Easy to start. Clear about limits.
Standard models are available without an account. Some frontier models require a verified email, and usage limits help keep the service available. Check important answers against reliable sources.
