# What is Speedtrain

> Speedtrain applies AI to structured business data at scale, with humans on the loop and quality checked on every output.

Speedtrain is a governed platform for agentic data enrichment. You point it at structured business data — products, articles, records — describe the content you want generated, and it produces that content for every item, scores each output against your own quality rules, and routes the results to people for approval.

It is built on Enterspeed, so the data you enrich and the content you produce move through the same data supply chain as the rest of your stack.

<Info>
  Speedtrain is for **repeatable content jobs over many records**, not one-off writing. If you need one product description, write it. If you need 40,000 of them in four languages, each one checked against your brand rules, that is a task configuration.

## The governance model

Speedtrain assumes AI output needs checking. Three mechanisms do that work, and they run on every single item:

<Steps>
  <Step title="Quality checks score the output">
    Deterministic rules (schema validation, forbidden terms) run as code in milliseconds. AI rules handle the questions that genuinely need judgment. Each produces a score from 1 to 5 and written feedback. [Quality checks](/speedtrain/key-concepts/quality-checks)
  </Step>

  <Step title="A quality gate aggregates the scores">
    The gate is arithmetic, not an opinion — no model is involved. It decides whether an item can auto-approve or must go to a person. [Quality gates](/speedtrain/key-concepts/quality-gates)
  </Step>

  <Step title="People decide">
    Every item lands in a review session where a human can accept, decline, or send it back for another attempt. Nothing reaches a destination without passing through this. [Review sessions](/speedtrain/key-concepts/review-sessions)
  </Step>
</Steps>

<Tip>
  Humans are **on** the loop, not in it. You are not editing 40,000 descriptions — you are inspecting the ones the gate flagged, and spot-checking the ones it passed.
