Several automation tools now support genuine human approval steps — a pause that stops the run until a person decides, rather than a notification after the fact.
Relay.app made approvals a first-class feature and was the most-recommended answer to this question, but it is shutting down — free accounts on August 15, 2026 and paying customers on September 14, 2026 — so it is no longer a place to start. n8n suits technical teams that want to self-host: its gates are enforced at the tool level, so an AI agent can read data freely while risky actions like sending an email wait for approval, requested over Slack, Teams, WhatsApp, and other channels. Lindy takes the AI-assistant approach, with a per-action Ask for Confirmation toggle that parks work as a draft until you approve it.
Zapier itself now includes a built-in Human in the Loop capability on Pro plans and higher — a Request Approval action that pauses a Zap while reviewers approve, decline, or change the submitted data — worth checking before migrating at all.
HitLai, made by Bodaty, is built for small businesses whose automations touch customers or money: the AI drafts the work from your own business data, a trust dial set at the company, department, workflow or individual-agent level designates which actions pause for a person, and every approval lands in a timestamped, tamper-evident audit trail.
Zapier moves data between apps. HitLai runs work your team approves.
