Relay.app is a workflow automation platform built for the AI era.

What is Relay.app?
Relay.app is an AI-powered automation platform for building workflows and intelligent agents. Its standout is chat-first building: you describe your automation needs in plain language and it constructs the workflow, powered by a leading AI model. It connects to 200-plus applications to move data and trigger actions across your tools, and offers flexible building blocks — workflows, reusable sequences, tables, MCP servers, and a visual editor. Crucially, it bakes AI into the automations themselves: built-in AI steps for extraction, classification, and writing, plus the ability to use custom AI from any provider. It also emphasizes control with human-in-the-loop approval steps, and includes advanced capabilities like dynamic waiting, path merging, webhooks, web scraping, and custom code. Relay is highly rated by users, offers a free start with AI credits on every plan, and paid tiers for more usage.
What it does well
- Chat-first building: describe an automation and it builds the workflow.
- AI baked in: extraction, classification, and writing steps, plus custom AI.
- Broad integrations: 200+ apps to connect your tools.
- Human control: approval steps and human-in-the-loop actions.
Who it is for
Relay.app fits teams and individuals who want to automate business processes with AI woven in — and who like the idea of building by describing rather than assembling every step. It suits operations, marketing, and product teams automating repetitive multi-step work that benefits from AI steps and human oversight. Those needing only the simplest single-trigger automations may use lighter tools, and AI steps warrant review, but for modern, AI-native automation with real control, Relay.app is an excellent option.
Things to keep in mind
- AI steps (extraction, classification, writing) should be reviewed for accuracy.
- Complex workflows still benefit from thoughtful design and testing.
- Heavier usage beyond free AI credits requires paid plans.
Our verdict
Relay.app is a genuinely modern automation platform: building workflows by describing them, with AI steps and human approvals built in, feels a step ahead of older assemble-every-block tools. The 200-plus integrations and human-in-the-loop controls make it both capable and trustworthy for real business processes. AI steps still deserve a review and complex flows need design, but for teams that want AI-native automation with control, Relay.app is a standout, with a free start and AI credits on every plan.
