Relay.app

Relay.app is an AI automation platform that turns a plain-language description into a working workflow. It is built for operations, marketing, sales, and small business teams who want to automate repetitive work without writing code. You describe what you want, Relay.app connects your apps and AI models, and you add human approval steps wherever a person needs to stay in control.

Key Highlights

• Chat-first builder, powered by Opus 4.8, that turns a prompt into an editable visual workflow
• Connects 200+ apps including Gmail, HubSpot, Stripe, Slack, and Notion
• Human-in-the-loop steps for approvals, data entry, and AI output review
• Built-in AI steps using models from Anthropic, OpenAI, or Gemini
• Workflows, tables, and custom MCP servers built from the same blocks
• Free AI credits on every plan, or bring your own API key

What Makes It Different

The differentiator is the human-in-the-loop model. Instead of letting AI run unsupervised, you drop a checkpoint anywhere in a workflow to require an approval, collect data only a person knows, or route an AI output to email or Slack for review before it goes out. That suits irreversible actions like payments and customer messages. Relay.app also keeps the predictable process separate from the AI, so automations stay reliable run to run.

Features & Capabilities

Workflows start from a trigger: an app event, a schedule, a form, a webhook, an RSS feed, or a manual button. From there you chain app steps, AI steps, conditional paths, loops, and merging branches in a no-code visual editor.

Beyond app actions, Relay.app adds HTTP requests for any API, web scraping (extract content, screenshots, crawl links), and utilities like custom JavaScript and file conversion. You can also build MCP servers to expose your own tools to apps like ChatGPT, Claude, or ElevenLabs.

User Ratings and Testimonials

Users praise the interface, often calling it cleaner and easier to learn than Zapier or Make, and they single out the human-in-the-loop design and fast support. Several reviewers note they are not programmers yet still build complex workflows. The common caveat is that included AI credits and step limits on lower tiers can run out under heavy use, pushing frequent users to upgrade or bring their own key.
