About Relay App
What is Relay App?
Relay App is a workflow automation and AI agent platform that connects applications, large language models, and human approval checkpoints into coordinated workflows.

It also features MCP server tools to expose automated workflows directly to AI assistants such as ChatGPT, Claude, and ElevenLabs.
