Relay.app is a workflow automation platform competing with Zapier and Make.com, differentiated by its emphasis on human-in-the-loop design — workflows where AI completes automatable steps but pauses for human input or approval when human judgment is needed, rather than running fully automatically.
The human-in-the-loop philosophy is built into Relay's design: a step can be configured to send a notification to a team member for review, approval, or additional input before continuing. This makes Relay appropriate for workflows where full automation would be risky but significant manual work can still be eliminated by automating the surrounding steps.
AI Steps within workflows use GPT-4 to process, classify, transform, or generate text as part of workflow automation — summarising customer emails before routing, classifying support tickets by topic, generating personalised responses from templates, or extracting structured data from unstructured inputs. These AI processing steps are embedded directly in the workflow without requiring separate AI API calls.
The visual workflow builder provides a multi-step automation canvas where each step is a connected node — similar in concept to Make.com but with Relay's cleaner UX and human-in-the-loop step type. Triggers include webhooks, email, forms, and scheduled runs.
At $9/month for Starter, Relay targets individuals and teams wanting modern workflow automation with built-in AI without the complexity of Make.com or the cost of enterprise automation platforms.
Relay.app runs as llm assistant software built around text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, with API access for teams that want to embed it into their own products.
