We’ve been building Sigma around a simple question:What happens if an AI conversation never has to restart?Most current AI systems are optimized around individual sessions. Start a new chat, and much of the continuity is lost.Sigma explores a different approach: persistent conversations that can continue across days, weeks, or months.Some of our early adopters are already running conversations exceeding 2,000 interaction cycles inside a single thread.We’re still very early, and this is an Open Beta.I’d especially love feedback from people building AI agents, research tools, AI companions, or experimenting with long-running AI interactions.What breaks first once AI conversations stop being disposable?
