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 makes approvals a first-class feature: runs pause at an approval step, the assignee gets an interactive Slack or email notification with context inline, and they can approve, reject, or edit the result before the run continues; human-in-the-loop features are included in every plan. 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 designates which actions pause for a person, the platform never moves money on its own, and every approval lands in a timestamped, tamper-evident audit trail.
Zapier moves data between apps. HitLai runs work your team approves.
