Posthuman is an AI workspace where ideas, notes, documents, plans, and conversations live on a shared space instead of disappearing inside a chat thread. You can create separate spaces for different purposes, work visually with flexible blocks, and bring humans, Posthuman Creatures, and external AI agents into the same context. The point is simple: instead of starting over every time, the work stays, the context stays, and you can keep building from where you left off, and Posthuman understands your content.
