Human gate blocks pause workflow execution at critical decision points — waiting for a reviewer to approve, reject, or correct AI-generated output before anything leaves the system. The human is never cut out of the loop.
Fully automated workflows sound appealing until an AI makes an error that goes unreviewed — a wrong material quantity in a $2M proposal, an RFI response that commits to a schedule you can't meet, a takeoff that missed a floor. In construction and manufacturing, the stakes are too high for unsupervised output.
RenderDraw's human gates are not a bolt-on afterthought. They are a first-class block type designed to make human review fast, frictionless, and auditable — not a roadblock, but a quality gate that catches errors before they become costly.
A gate-equipped workflow is not slower than a manual process — it's dramatically faster, because the human is reviewing AI-drafted output that is already 80–90% correct, rather than producing it from scratch.
The simplest gate type. The workflow pauses and notifies the configured reviewer. The reviewer sees a summary card showing the key workflow data — AI-extracted fields, proposed content, pricing summary — and clicks Approve or Reject.
On approval, the workflow continues to the next block. On rejection, execution routes to a configured fallback path (loop back for correction, escalate, or terminate with notification).

Rather than a simple approve/reject, the structured review form presents the reviewer with a configurable set of editable fields — pre-populated with AI-generated values. The reviewer can accept the AI's output, correct individual fields, or override entirely.
This is the right gate type when the AI does most of the work but human judgment is needed to verify specific values — quantities in a takeoff, unit prices in a quote, schedule dates in an RFI response.
All field values — both the AI-generated initial values and the reviewer's final values — are stored in the audit log so you can track how often and how much reviewers change AI output over time.
Correction feedback loop. Reviewer corrections to AI-generated values can be optionally fed back into knowledgebase update workflows — building a closed loop where AI accuracy improves over time from reviewer behavior on the gate.
Mobile-friendly review. The review form is fully responsive. Reviewers can approve or correct from their phone via the email notification link — no need to open a laptop for routine approvals.
For high-value or high-risk decisions that require more than one human approval. Configure a list of required approvers and a quorum rule — unanimous approval required, or any N of M approvers must approve within the SLA window.
Notify all approvers simultaneously (parallel) for fastest response, or route approvals sequentially (approver 1 must approve before approver 2 is notified) for tiered governance workflows.

The conditional gate only activates the human review step if a configured condition evaluates to true at runtime. When the condition is false, the gate passes automatically and the workflow continues uninterrupted.
This lets you build "smart gates" that apply human oversight proportional to the risk of a given workflow run — routine small-value bids flow through automatically while high-value or complex bids always get reviewed.
Audit transparency. Even when a conditional gate passes automatically (condition was false, no review required), the gate block records the evaluation result and the auto-pass decision in the audit log. You always have a record of why a workflow run bypassed human review.
Every human gate can be configured with a response SLA — a maximum duration the workflow will wait before taking escalation action. SLA timers start when the gate notification is sent to the reviewer.
SLA timers support business hours mode — a 4-hour SLA in business hours mode will only count time during configured working hours (e.g., 8 AM – 6 PM, Mon–Fri in the reviewer's timezone), so a Friday afternoon assignment doesn't expire over the weekend.
One-click from email. Reviewers can approve or reject directly from the email notification without logging into the platform. Security: each link is single-use, time-limited (configurable, default 72 hours), and tied to the reviewer's identity via a signed token.
Every gate interaction is logged in the workflow run audit trail — providing a permanent, queryable record of human oversight activity for compliance, quality, and process improvement purposes.
The RenderDraw platform provides built-in run analytics views filtered by gate decision, reviewer, date range, and workflow type. Export audit data as CSV or connect to your BI tool via the analytics API.
Gate audit data is retained for the full run retention period (configurable, minimum 7 years for enterprise plans).
Human gates let you automate without fear. Every AI-generated output that matters gets a human checkpoint before it leaves the system.
