What is Relay AI
Relay AI is a platform for creating practical AI agents that automate work across 100+ business apps. Going beyond brittle trigger–action chains, it combines a visual workflow builder with one-click AI assistance, enabling agents to read context, choose next steps, and take actions in tools like Gmail, Slack, and Notion. With human-in-the-loop reviews and a multiplayer collaboration model, teams can co-design, approve, and monitor automations to scale routine tasks while preserving control, transparency, and reliable outcomes.
Relay AI Key Features
- AI agent workflows: Build agentic workflows that understand context, branch intelligently, and make decisions instead of following rigid triggers only.
- 100+ app integrations: Connect Gmail, Slack, Notion, and other popular SaaS tools in minutes to read data, create records, send messages, and update systems.
- One-click AI assistance: Use AI to draft emails, summarize threads, extract fields, classify content, and fill steps with smart defaults to speed up build time.
- Human-in-the-loop control: Insert approval and review gates so people can validate AI outputs, edit drafts, or re-route exceptions before actions are taken.
- Multiplayer collaboration: Co-build workflows, assign reviews, and track runs together, making automation a shared team process instead of a solo task.
- Reusable components: Save prompts, steps, and patterns as building blocks so teams can standardize processes and scale best practices.
- Observability and audit trails: Monitor runs with logs, outcomes, and handoffs to maintain accountability and improve reliability over time.
- Flexible logic: Combine AI steps with rules, conditions, and data mapping to balance determinism with AI-powered reasoning.
