Cotal vs nornweave

Cotal: Cotal is an open, provider-agnostic, and cross-machine capable pub/sub standard designed for AI agents to collaborate in a shared space. It allows users to define any agent topology, from flat peer teams to hierarchical structures, and facilitates robust communication with features like durable delivery and presence.; nornweave: NornWeave is an open-source, self-hosted Inbox-as-a-Service API that provides a stateful and intelligent layer for email communication, specifically designed for AI agents and LLMs. It transforms raw email data streams into coherent threads, parses content into clean Markdown, and offers features like semantic search and LLM-generated summaries.
