Human review

Add human decision points when it matters, control AI output quality.

Human review nodes pause an agent's steps to let users review, choose between options, or make refinements before continuing.

How it works

When your agent reaches a Human review node during execution in App mode, it stops and asks for human intervention. The user can review what's been generated so far, regenerate if needed, or refine inputs before the agent continues its job.

This is especially valuable when you want users to have choice and control over the creative process rather than fully automated generation.

Adding it in Studio

Drop a Human review node anywhere in your workflow where you want execution to pause for a human decision. It accepts the output of the upstream node as its input and passes the selected (or refined) result to the downstream node once the user continues.

The node works with any modality. It can pause on images, videos, text, or any other asset type your workflow produces, so the review step adapts to whatever the preceding node generates.

Use cases

• Pick the best option. Generate several variations and let the user choose their favorite before committing to a more expensive downstream step, such as selecting a key visual before generating a video from it.

• Discard what doesn't work. Let users drag unwanted results out of the selection so only the kept assets flow to the next step.

• Review and refine before continuing. Give users a checkpoint to edit or regenerate an asset, so quality is confirmed at a human gate rather than after the full run completes.

• Control cost on heavy workflows. Place a review gate before resource-intensive steps (video generation, large batches) so credits are only spent on approved inputs.
