Magai is a multi-model AI workspace that puts ChatGPT, Claude, Gemini, Grok, and dozens of other text, image, and video models into a single chat interface. You can switch models mid-conversation without losing context, thanks to a shared memory layer that carries your instructions across providers. It adds agents (packaged instructions that run on any model), scheduled tasks, team workspaces with per-client isolation, and a document canvas that exports to PDF or DOCX. A key privacy stance: your prompts, files, and outputs are never used to train any model, by Magai or its providers. Founded by Dustin W. Stout in 2023, it is a paid-only product with a 30-day money-back guarantee—there is no free plan and no trial.
