Relay App: AI Workflow Automation With 200+ App Integrations
What is Relay App
Relay App is an AI automation platform where users describe the process they want in plain language and the service assembles the workflow for them. A conversation with the builder, powered by a frontier model, produces an initial set of steps that can then be reviewed and adjusted in a visual editor. Workflows link more than 200 popular apps, draw on leading AI models, and keep decisions predictable through branching, loops, and data transformations. Human-in-the-loop actions let a teammate approve a decision, review AI output, or supply missing information before the process continues. Accounts are free to create, and the interface is available in English and Chinese, so a small team can test how automation fits daily operations without a large setup project.
How does Relay App work
Each run starts with a trigger that decides when the workflow should act, such as a new record in a connected app or a recurring schedule. Relay App then works through the steps added to the workflow, passing data from one action to the next and applying branches, loops, and transformations where the process needs them. AI actions handle extraction, summarization, or classification, and a custom prompt can call a chosen model when the built-in options are too narrow. Before an important action, a human step can hold the run until someone approves the result or fills in missing details.
Benefits of Relay App
Relay App lowers the effort of automation because the first draft comes from a conversation rather than a blank canvas. Runs stay dependable: the process follows defined steps, and AI handles extraction, summarization, and classification inside clear boundaries, so results are repeatable rather than improvised. Approval and review steps let a person correct or complete the output before the workflow acts on it, which suits processes that touch customers, invoices, or records. Connections to more than 200 apps, reusable sequences, MCP servers, and tables keep related work in one place instead of stitching tools together by hand.

Core Features of Relay App
Describe a Workflow in Chat
Users explain the apps and steps they want to connect in natural language, and the builder turns that conversation into a working draft.
Refine Steps in a Visual Editor
The editor shows the sequence of steps, conditions, and data flow, so users can adjust logic without turning the process into a wiring diagram.
Triggers for Every Starting Point
Workflows can begin from an app change, a schedule, a form, a webhook, an email, an RSS item, a table row, or a manual run.
AI Actions With Model Choice
Built-in actions extract data, summarize text, and classify records, while custom prompts allow a specific model and output format.
Human-in-the-Loop Checkpoints
A step can pause for an approval, a review of generated content, or a request for information that a person supplies.
MCP Servers and Shared Tables
Custom tools can be exposed to assistants such as ChatGPT and Claude, and structured data can be stored in tables that workflows read and update.
Use Cases of Relay App
- Sales teams: Collect a new lead, organize its details, and prepare a follow-up for review.
- Managers: Turn meeting notes into a short update and share next actions with the team.
- HR teams: Coordinate onboarding checklists, account requests, and welcome messages in one sequence.
- Operations: Extract document details and flag missing information for a person to resolve.
- Marketing teams: Move a draft through research, editing, review, and a final handoff.
FAQs of Relay App
What is Relay App?
Relay App is an AI automation platform for building agents and workflows in natural language. It connects hundreds of apps and leading AI models so repetitive business processes can run with fewer manual steps.
Who is Relay App for?
The product targets teams that handle repeatable operations such as lead qualification, onboarding, reporting, and document processing. Small businesses and operations, sales, marketing, and HR groups can start from a template or describe their own process.
How does a workflow start?
Every workflow begins with a trigger, which can be a change in a connected app, a schedule, a form submission, an incoming email, a webhook, a table row, or a manual run that a user starts.
Can a workflow use a specific AI model?
Built-in AI actions cover data extraction, summarization, and classification. When a task needs different behavior, users write a custom prompt, choose a model, and define the output format for the next step.
How does human review fit into a run?
A workflow can pause for an approval, a review of AI-generated content, or a request for information. The run continues only after the assigned person responds, which keeps decisions involving customers or money under human control.
Is there a free plan?
Creating an account is free, and paid automation plans are not currently offered on relayapp.org. Users can read the workflow examples and manage their account there, while the archived illustrations describe plans on the original Relay.app service.
Which apps can be connected?
The platform works with more than 200 popular apps, and webhooks or custom HTTP requests cover services that lack a built-in connection. Availability of a specific integration depends on the service being used.
