# Scan Text And OCR Output

Use Mighty on plain text, extracted text, OCR output, and IDP fields before downstream automation trusts them.

## Goal

Scan text before it reaches AI, search, indexing, workflow automation, or a human review queue.

This is the right guide when you already have text. That text can come from a form, chat message, OCR engine, IDP pipeline, email parser, PDF extractor, or agent tool.

## Architecture

1. Receive text from the user or pipeline.
2. Call `POST /v1/scan` with `content_type=text`.
3. Store `scan_id`, `request_id`, `scan_group_id`, and `action`.
4. Route `ALLOW`, `WARN`, or `BLOCK`.
5. Only send safe or reviewed text to downstream AI or automation.

Use `data_sensitivity=tolerant` when OCR text normally contains names, addresses, phone numbers, policy numbers, invoice numbers, or claim details.

`threats` is an array of objects with `category`, `confidence`, an optional `evidence` excerpt, and a human-readable `reason`.

## Routing Logic

```ts
export function routeScannedText(scan: { action: string }) {
  switch (scan.action) {
    case "ALLOW":
      return { decision: "continue" as const };
    case "WARN":
      return { decision: "queue_review" as const };
    case "BLOCK":
      return { decision: "stop" as const };
    default:
      return { decision: "queue_review" as const };
  }
}
```

## AI Fraud And OCR

OCR text can carry hidden or altered instructions. A PDF can contain normal visible text plus hidden text that says to ignore policy, approve a claim, or exfiltrate data. Mighty helps catch those signals before your AI or IDP system treats the text as trusted.

Honest wording for your product: "This item was flagged for review." Avoid saying "This item is fraudulent" unless your own review process confirms it.

## Production Checklist

- Keep original text and scanned text versioned if your retention policy allows it.
- Store `scan_group_id` with the workflow record.
- Send model output from the same workflow with `scan_phase=output`.
- Log `request_id` and `scan_id`.
- Route unknown scan errors to review when the workflow is high risk.
- Use `data_sensitivity=tolerant` for expected contact PII.

## AI-Agent Prompt

### Add OCR output scanning

```text
Add Mighty scanning to the OCR or IDP pipeline.

Requirements:
- Use server env MIGHTY_API_KEY.
- Call POST https://gateway.trymighty.ai/v1/scan.
- Send extracted text with content_type=text and scan_phase=input.
- Use mode=secure, focus=both, data_sensitivity=tolerant.
- Store scan_id, request_id, scan_group_id, session_id, action, risk_score, and threats.
- Route ALLOW to continue.
- Route WARN to human review.
- Route BLOCK to stop or require manual override.
- Do not send WARN or BLOCK content to downstream AI without review.

Acceptance criteria:
- Unit tests cover ALLOW, WARN, BLOCK.
- Integration code never exposes MIGHTY_API_KEY to the browser.
- Logs include request_id and scan_id.
