Relay.app (relay.app) is a workflow automation platform designed around a fundamental premise: not every step should be automated. Where Zapier and Make route data between apps as fast as possible, Relay builds human checkpoints directly into workflows — so your team can review AI-drafted emails before they send, approve contract changes before they go live, or confirm data edits before they write to your CRM. The result is automation that businesses can actually deploy in customer-facing and compliance-sensitive workflows.
Key Features
- Human approval steps — add a "wait for human" checkpoint anywhere in a workflow; the assigned person reviews and approves before the automation continues
- AI-assisted steps — generate draft content, classify data, extract information, and summarize inputs using built-in LLM actions
- Collaborative workflows — assign steps to specific teammates; the workflow pauses and notifies them via Slack or email
- App integrations — connects to HubSpot, Salesforce, Gmail, Slack, Notion, Airtable, and 100+ other tools
- Conditional logic — branch, filter, and loop based on field values, AI classifications, or human decisions
- Audit trail — full history of who approved what and when, for compliance and accountability

Who Should Use Relay.app?
Relay.app is the right automation tool for business teams where full automation is not yet appropriate — customer success teams reviewing AI-drafted responses before sending, finance teams approving data entries, or ops teams managing multi-step processes that require human judgment at specific points. It fills the gap between Zapier (full automation, no humans) and manual processes, making it ideal for compliance-sensitive industries and customer-facing workflows.
