Relay.app

Relay.app is a workflow automation platform designed to help teams build AI agents that work alongside humans. It combines traditional automation capabilities with AI-powered features and unique human-in-the-loop functionality, allowing workflows to pause for human decisions, approvals, or data inputs before continuing. The platform integrates with over 100 popular apps and is trusted by teams at companies like Cursor, Ramp, and Motion.

• AI Agent Creation enables users to build custom AI agents by giving them names, teaching them skills, and providing feedback to improve performance over time using models like GPT, Claude, and Gemini.

• Human-in-the-Loop functionality allows workflows to pause for approvals, manual data inputs, tasks, and manual path selection, ensuring human judgment remains part of automated processes.

• 100+ Integrations connect with popular apps including Gmail, Slack, Notion, HubSpot, Salesforce, Google Sheets, Airtable, Linear, and many more for seamless workflow automation.

• Multi-Step Workflows support complex automation with paths, merging paths, wait steps (time-based and event-based), iterators for looping, and batch triggers.

• AI-Powered Actions include data extraction, classification, summarization, translation, audio transcription, text-to-speech, and image generation using built-in AI credits.

• Utility Tools provide data formatters, web scraping, custom JavaScript execution, PDF converters, file utilities, and list operations for comprehensive data manipulation.

• Webhook Support enables webhook triggers, HTTP requests, and waiting for incoming webhooks to integrate with external systems and APIs.

• Team Collaboration features include multiplayer roles, workflow sharing, and app connection sharing for teams working together on automation projects.

To get started, sign up for a free account which includes 200 steps per month and 500 AI credits. Create your first workflow by selecting a trigger from one of the integrated apps, add steps to define your automation logic, and optionally include human-in-the-loop steps where manual intervention is needed. Test your workflow using the built-in testing tools that provide clear feedback on each step, then activate it to run automatically.
