Relay.app
Build AI agents that work across your entire stack — with human-in-the-loop checkpoints for the decisions that matter.
Relay.app lets non-technical operators build AI agents using plain English across 100+ apps — Gmail, Slack, HubSpot, Notion, Airtable, and more — with built-in human-in-the-loop controls.
What it does
Relay.app lets non-technical operators build AI agents using plain English across 100+ apps — Gmail, Slack, HubSpot, Notion, Airtable, and more. Its key differentiator is human-in-the-loop design: agents run autonomously but can pause and surface decisions to a human when the stakes require it.
Built on four frameworks — workflows, sequences, tables, and MCP servers — Relay handles everything from email triage to CRM updates to multi-step campaign coordination. Frequently cited as the approachable alternative to Zapier/Make for marketing and ops teams who want real agent behavior without engineering overhead.
