# QA Check

> Score a text from 0 to 1 with an AI model for content, quality, consistency or safety, and get an approved or rejected decision with a short reason.

Source: https://nodaro.ai/docs/nodes/automate/qa-check

The **QA Check** node asks an AI model to score a text from 0.0 to 1.0 against one check type, such as quality or safety. The text is approved when the score reaches your threshold, and the model explains its decision in one short reason. Use QA Check as an automatic quality gate, for example to catch a weak script or caption before anyone publishes it.

- Found in: Automate › Logic & Data
- Output: text
- API type: `qa-check`

## When to use it
- Check that a generated script is complete and well structured before you turn it into audio or video.
- Check captions for clarity and grammar before they are posted.
- Screen a text for harmful or offensive content before it goes public.
- Compare the scores of several drafts to see which prompt writes better text.

## Quick start
### Add the node

Press Tab on the canvas and choose **Automate › Logic & Data › QA Check**.

### Connect the text

Wire the text to check into the **Input** input, for example from a [Prompt](https://nodaro.ai/docs/nodes/automate/prompt) node, a [Generate Script](https://nodaro.ai/docs/nodes/video/generate-script) node or a [Text](https://nodaro.ai/docs/nodes/automate/text) node.

### Choose the check

Open the settings panel. Choose a **Check Type** and a **Threshold**, and a different **AI Model** if you want one.

### Run it

The node shows the score, the decision and the model's reason. The reason also leaves through the **Approved** or the **Rejected** output, whichever matches the decision.

Workflow: A Prompt node writes a caption from your brief, and QA Check scores it for clarity, grammar and professionalism.

- Text → Prompt (prompt)
- Prompt → QA Check (input)

## Inputs and outputs
| Input or output | Accepts or sends | What it does |
| --- | --- | --- |
| **Input** | Text | The text to evaluate. Required. |
| **Approved** | Text | The model's reason, when the score is at or above the threshold. |
| **Rejected** | Text | The model's reason, when the score is below the threshold. |

On each run, only one of the two outputs carries a value. Both carry the reason, not the checked text. To use the checked text in later steps, connect those steps to the node that wrote it.

## Check types

| Check Type | What the model evaluates |
| --- | --- |
| **Content** (default) | Completeness, coherence and structure. |
| **Quality** | Clarity, grammar and professionalism. |
| **Consistency** | Internal consistency: no contradictions and no logical errors. |
| **Safety** | Whether the text is safe and appropriate, with no harmful or offensive material. |

## Settings
| Setting | What it does |
| --- | --- |
| **AI Model** | The model that scores the text. The default is **Gemini 3.6 Flash**. |
| **Reasoning Effort** | How much the model reasons before it answers, on models that support it. **Very high** and **Max** may bill one tier up. |
| **Advanced mode** | Available on Gemini models only. It unlocks **Temperature**, **Max Tokens** and the full reasoning range, which appear once it is on. It costs one credit tier more, and the price on the node updates at once. On other models the switch is disabled and says why. |
| **Check Type** | What to evaluate: **Content**, **Quality**, **Consistency** or **Safety**. |
| **Threshold** | The lowest score that counts as approved, from 0 to 1. The default is 0.7. |

## Credits
QA Check is billed like the other AI text nodes: the price follows the tier of the model you choose. A **Reasoning Effort** of **Very high** or **Max**, or **Advanced mode**, can move the check one tier higher. The node shows the price for your current settings before you run it. See [Credits](https://nodaro.ai/docs/concepts/credits).

## Tips
- **Match the check to the risk.** Use **Safety** for anything that is published automatically, and **Content** or **Quality** for drafts.
- **Tune the threshold on real examples.** Run the check on a few texts you already judged yourself, then raise or lower **Threshold** until the decisions match yours.
- **Pick between drafts instead.** To keep the best of several texts rather than score one, use [Choose Best](https://nodaro.ai/docs/nodes/automate/choose-best) with **AI picks the best**.
- **Check images with Image Critic.** QA Check reads text only. For pictures, use [Image Critic](https://nodaro.ai/docs/nodes/image/image-critic).

## Frequently asked questions

### What does QA Check return?

A score from 0.0 to 1.0, a decision, and a short reason written by the model. The text is approved when its score is at or above the Threshold, which is 0.7 by default.

### Which check types does QA Check offer?

Content checks completeness, coherence and structure. Quality checks clarity, grammar and professionalism. Consistency looks for contradictions and logical errors. Safety checks that the text is free of harmful or offensive material.

### What do the Approved and Rejected outputs carry?

The model's reason. Approved carries it when the text passes, and Rejected carries it when the text fails. Only one of the two has a value on each run, and neither carries the text you checked.

### How much does QA Check cost?

QA Check is billed like other AI text nodes, so the price follows the tier of the model you choose. A very high reasoning effort or Advanced mode can bill one tier higher. The node shows its price before you run it.

### Can QA Check score images?

No. QA Check reads text. To score an image for realism, prompt adherence or consistency, use the Image Critic node.
