What is Relay.app?

Relay.app is an automation platform whose distinguishing feature is the deliberate pause. A workflow can stop mid-run, present what it has produced to a person, and wait: approve, edit, or reject. Only then does it continue. That step is a first-class part of the product rather than a workaround.

This matters for the work most teams are reluctant to hand over entirely. Drafting a reply to a customer, sending an outreach message, updating a record that someone will act on — the automation saves the effort of composing, while a person keeps the final say. Relay also includes AI steps for summarising, extracting and translating without requiring separate accounts or API keys.

It is a younger platform than the established names, and the reviews reflect that: strong on AI integration and ease of use, with gaps in utility features that mature tools have long since filled. Users also report occasional trouble with trigger reliability and timestamp handling.

How Relay.app Works

How It Works

Workflows are built from a trigger and a sequence of steps, as in other automation tools. The difference is the human-in-the-loop step: it sends the current state of the run to a person via email or Slack, waits for their decision, and branches on the response. AI steps are built in — summarising content, extracting fields, translating text — and run without a separate model subscription. Integrations cover more than a hundred applications, weighted toward the tools teams use for communication and CRM.

Who Should Use It

Relay.app suits teams automating work that touches customers or carries consequences, where full automation feels premature: support drafting replies for review, sales sending outreach a person signs off, operations processing requests that need a judgement before they complete. It fits anyone who has built an automation and then disabled it because the output could not be trusted unsupervised.

Benefits

The approval step turns automation from all-or-nothing into something adoptable: you can automate the drafting without automating the sending. AI steps included in the platform remove the friction of managing separate model accounts and keys. The interface is clean, the templates useful, and the documentation clear enough to get productive quickly.

Limitations

Relay.app does not publish a price list. `relay.app/pricing`, `/plans` and `/pricing/` all return a 404, and no pricing link appears on the home page — which makes budgeting impossible without contacting them. Reviewers note missing utility features such as workflow duplication, and report accuracy problems with triggers and timestamp formatting. The integration catalogue is small next to the established platforms.

Frequently Asked Questions

What does Relay.app cost?
Relay.app does not publish a price list. The usual pricing paths return a 404 and no pricing link appears on the home page, so the current figures have to come from the vendor directly. We have deliberately left the price fields empty rather than guess.
What is a human-in-the-loop step?
A point where the workflow pauses and asks a person to approve, edit or reject what it has produced before continuing. It lets you automate the work of drafting something without automating the decision to send it.
How does Relay.app compare to Zapier?
Zapier has far more integrations and runs workflows to completion without interruption. Relay.app has fewer connectors but builds approval into the flow, which suits work where unsupervised automation is not acceptable.
Is Relay.app the same as Relai?
No. Relai is a Bitcoin app and unrelated. The similarity of the names makes searching for either of them harder than it should be.
