Our verdict
Relay.app stands out in a crowded automation market with an original proposition: native AI integration as a first-class action in workflows, alongside conditional logic and human approvals. This hybrid approach is especially relevant for processes that cannot be 100% automated — where occasional human validation is needed — without sacrificing automation fluidity. Direct access to the best models (GPT-4o, Claude 3.5, Gemini) without complex technical configuration is a major asset. The free plan with 200 steps and 500 AI credits suffices for small teams and early-stage projects. At $19/month, the Professional plan offers solid value for regular use. The main limitation concerns step volume: intensive workflows will quickly exceed lower-tier quotas. Relay.app is a perfect fit for operational and marketing teams who want to automate intelligently without technical dependency, while retaining control over critical decisions through human approval steps.
