What is Relay.app?
Relay.app is a modern AI-powered workflow automation platform that lets users build AI agents and multi-step automations by describing what they want in plain English. The tool converts natural language prompts into visual, reliable workflows that connect across 200+ popular apps including Gmail, Notion, HubSpot, Slack, Airtable, and many more. Its core construct is the workflow—a trigger followed by a series of steps that can call apps, use AI, transform data, and include conditional paths, loops, and filters.
Key features that set Relay.app apart include its unique human-in-the-loop capabilities, which allow teams to add approval checkpoints, data input steps, and AI output reviews anywhere in a workflow. The platform offers built-in AI templates for extraction, classification, analysis, and writing, plus custom AI steps with any model from providers like Anthropic, OpenAI, and Gemini. Advanced primitives include dynamic waiting (pausing for set durations or until conditions change), portable rich text outputs that work across email/chat/docs, reusable sequences (sub-workflows), MCP servers for AI agent integration, and tables for storing structured stateful data.
Relay.app is designed for businesses of all sizes—from small business owners and freelancers to enterprise teams—who want to automate back-office processes like lead qualification, employee onboarding, invoicing, customer support ticket handling, and deal pipeline reporting. It caters particularly well to non-technical users who need powerful automation without engineering expertise, while still offering developer features like custom JavaScript execution, webhook triggers, HTTP requests, and secret stores. Thousands of businesses trust it for automating repetitive work across their tech stack.
The platform emphasizes an intuitive visual editor that provides precise control without creating complex

Frequently asked questions about Relay.app
What is Relay.app?
Relay.app is a modern workflow automation platform that lets you build AI agents and multi-step automations by describing what you want in plain English. It converts your description into a visual workflow that connects and automates actions across 200+ apps you already use. Relay.app features deep integrations, rich workflow tools including conditional paths and loops, and human-in-the-loop steps for bringing human decisions, tasks, and approvals into automated workflows.
What is a workflow?
A workflow is the template for an automated process in Relay.app. Every workflow starts with a trigger (from an app event, schedule, manual click, form submission, or webhook) and is followed by one or more steps that perform automations. Every time your trigger activates, a new run of the workflow starts. Steps can call apps, use AI, transform data, and include paths, loops, and filters.
How does Relay.app's pricing work?
Relay.app has plans for teams of every size, starting with a Free plan for 1 user running 100 automations per month with 500 AI credits. The Professional plan is $19/month per user (billed annually) with 2,000 AI credits. The Team plan is $59/month for 10 users (billed annually) with shared workflows and connections. Enterprise has custom pricing. All features are included in every plan, and you can upgrade monthly step limits or AI credits, or purchase one-off top-ups.
How many integrations does Relay.app support?
Relay.app currently has integrations with 200+ third-party apps including Gmail, Notion, HubSpot, Slack, Airtable, Asana, Zendesk, Salesforce, Stripe, and many more. The platform prides itself on designing deep, robust integrations with top tools used by modern teams. New integrations are constantly added, and you can request additional apps at [email protected].
What counts as a user?
Everyone in your team with a Relay.app account counts as a user. The Free plan includes 1 user, Professional includes 1 user, Team includes 10 users, and Enterprise has custom user limits. Shared app connections allow teammates to use the same account for shared inboxes and service accounts without each person counting as a separate user for that connection.
What counts as a step?
In general, every item that's numbered in your workflow consumes a step every time it runs. There are exceptions—notably triggers don't consume steps. Steps include app steps, AI steps, human-in-the-loop steps, utility steps, HTTP requests, and data transformations. The Free plan includes 200 steps/month, while paid plans have unlimited steps.
What are AI credits?
AI credits power AI steps in Relay.app for tasks like extraction, classification, analysis, and writing. Every plan comes with a free amount of AI credits that refresh every month: Free has 500/month, Professional and Team have 2,000/month. You can easily upgrade or top-up AI credits if you need more, or use your own API key for model providers like GPT, Claude, and Gemini.
How do I get support?
The Relay.app team provides outstanding customer support with speedy response times, striving to reply within 24 hours or sooner and resolve minor issues within 48 hours. Reach out to [email protected] and they'll get back to you promptly. Users consistently praise the support team for being fast, helpful, and even fixing bugs on the same day they're reported.
What is human-in-the-loop automation?
Human-in-the-loop is Relay.app's signature feature that lets you add human judgment anywhere in a workflow. You can add approval steps (workflow pauses until someone approves), data input steps (collect missing details via form), and AI output reviews (require human review before continuing). This is essential for payments, customer communications, and irreversible actions where AI alone isn't sufficient.
Can I use my own AI API keys?
Yes, Relay.app supports bringing your own API keys for model providers. While every plan includes free AI credits that work with GPT, Claude, and Gemini, you can also use your own API keys for these providers or other models. Custom AI steps let you choose any provider and model, mix and match providers, and design your own AI steps with custom tools and MCP connections.
