Relay.app

Relay.app is a modern workflow automation platform that connects the applications teams use every day and automates repetitive processes, with a particular emphasis on combining automation with human judgement and artificial intelligence. Many automation tools are either too simple to handle real business processes or too technical for non-developers, and they typically assume that every step can run without human involvement. In practice, many workflows require approvals, reviews or input from people at certain points. Relay.app addresses this by making human-in-the-loop steps a first-class feature, allowing workflows to pause for a person to review, approve or provide information before continuing. Its core approach is to provide an intuitive, well-designed builder that makes multi-step automations easy to create and understand, while integrating AI capabilities for tasks such as summarising, extracting and generating content.

Key features include a visual workflow editor, triggers and actions across a wide range of popular applications such as Gmail, Google Sheets, Slack, Notion, HubSpot, Salesforce, Asana and Airtable, conditional paths, loops, scheduled runs, webhooks and built-in AI steps powered by leading large language models. Human-in-the-loop capabilities include approval requests, data entry tasks and assignments to specific team members, with notifications delivered through email or collaboration tools. Templates help users get started with common workflows, including meeting follow-ups, lead routing, content creation and customer onboarding, while run histories provide transparency and troubleshooting support. Relay.app is delivered as a cloud service and requires no coding. It is aimed at operations teams, marketers, sales teams, founders, agencies and knowledge workers in organisations of all sizes that want reliable, collaborative automation. Its clean interface and clear run logs are intended to make automations easy to maintain as teams build a growing library of workflows over time. Pricing starts from around USD 9 per month; a free version is available alongside a free trial of the paid plans.
