Relay.app
FreemiumAI automation with humans in the loop
What is Relay.app?
Relay.app is workflow automation with humans in the loop: build multi-step automations across Gmail, Slack, Notion, HubSpot and more, drop in AI steps for drafting, extraction and classification, and add approval checkpoints where a person reviews before the workflow continues. That mix makes it feel safer than fire-and-forget automation for client-facing work. It offers fewer integrations than Zapier’s thousands, and very complex branching still fits better in Make or n8n.
