Relay.app is an AI-powered workflow automation platform that transforms plain language into reliable, visual workflows across 200+ integrated applications. Unlike traditional automation tools that require technical expertise, Relay.app lets anyone chat with its built-in AI agent to create, edit, improve, and analyze complex workflows without writing code. The platform includes access to all major AI models — OpenAI GPT, Anthropic Claude, and Google Gemini — running on Relay's own AI credits, so users don't need separate API keys. A key differentiator is its human-in-the-loop capability: teams can insert review and approval steps anywhere in a workflow, keeping humans in control of AI-generated outputs. Relay.app also supports advanced technical use cases with custom code steps, branching and looping logic, webhooks, and custom HTTP calls. Rated 4.9 on G2 and 5.0 on Capterra, it has won the Best for Operations & Compliance Teams Award for AI Workflow Automation in Winter 2026, and is trusted by teams ranging from solo founders to enterprise operations.
