Relay.app is an automation platform built around a simple idea: some workflows are too important to run fully unattended. It lets you insert approval checkpoints where a person reviews, edits, or approves before a critical step runs, blending automation with human judgment.

AI is woven throughout to draft messages, extract information, and classify content, and the modern builder makes designing these part-automated, part-human flows unusually pleasant. It suits teams automating outreach, onboarding, and approvals.
