Sublayer

Sublayer is rethinking what a product management app looks like when generative AI and LLMs sit at the very center of it. Rather than treating AI as a side feature bolted on, Sublayer designs the whole workflow around it — complete with a clear process for human approval and hands-on interaction with AI, so you stay in control instead of handing decisions over to a black box.

Under the hood, Sublayer is a model-agnostic AI agent framework written in Ruby, along with the infrastructure needed to support AI agent swarms working together. It ships as a Rubygem, making it straightforward for developers to spin up AI agents and AI-powered automations quickly, without locking themselves into a single model provider or getting stuck when a better model comes along.
