lemma-platform vs sema

lemma-platform: Lemma is an open-source platform for building and deploying AI teammates that learn from your team and integrate into existing communication channels like Slack and WhatsApp. It enables the creation of custom AI agents, apps, and automated workflows, managed within self-contained "pods" for enhanced collaboration and operational efficiency.; sema: Sema is a Lisp dialect that integrates LLM agents as core language primitives, providing a robust runtime that handles common agent scaffolding like retries, caching, and tool dispatch. It compiles to a fast bytecode VM, allowing LLM-powered scripts to be concise, shipped as single binaries, and easily understood by coding agents.
