Data quality platforms tell humans what data to trust. Atlan is the context layer for AI that makes sure every agent knows the same thing.

Before an AI agent acts on your data, it needs to know whether to trust it: is this asset complete? Is it fresh? Has it been certified? Atlan scores every critical asset automatically — and propagates that quality context along lineage to every downstream agent, so they know which data to trust before they act.

Data quality was built to catch bad data for humans. AI needs to know what's trustworthy too.

Data quality platforms were built for data engineers and stewards — monitoring pipelines, alerting on anomalies, scoring freshness and completeness so humans could decide which data was safe to use. The right tool for a world where humans were the primary consumers of data.

AI agents don't receive quality alerts. They don't review monitoring dashboards before querying. Without quality context surfaced through the context layer, an agent has no way to know whether the data it's acting on is complete, fresh, or certified. It produces answers from stale tables, missing values, and assets your team flagged as unreliable months ago — not because the model is wrong, but because it never knew the data was.

Atlan is the context layer for AI — the infrastructure that makes every AI agent in your stack accurate, trustworthy, and production-ready. The context layer is broader than quality: it includes governance, semantic definitions, lineage, and the institutional business knowledge encoded in every query and dashboard your team has built. But quality context is foundational. Every agent needs to know which data to trust before it can act on it correctly.

Vera, Atlan's Data Quality agent, continuously scores your critical assets on completeness, accuracy, and freshness. Those scores propagate along Data Lineage to every downstream asset and every AI agent automatically — so quality context travels with your data, not behind it. Context Engineering Studio tests whether agents are producing correct answers against your existing dashboards and business questions — surfacing when quality gaps are causing agents to get things wrong, before users find out in production.

What We Believe

From data quality monitoring to quality context that every agent knows.

The context layer for AI spans governance, semantic definitions, lineage, and business knowledge — but quality context determines which data any agent should trust. Here's how Atlan delivers it automatically.

Quality context scored automatically

Quality context scored automatically

Vera, Atlan's Data Quality agent, scores every critical asset on completeness, accuracy, and freshness — continuously, at scale. No manual DQ rule-writing. No monitoring dashboards to review before an agent queries. Quality context is embedded in the asset itself, always current.

Quality context propagates along lineage

Quality context propagates along lineage

Data Lineage carries quality signals downstream. When Vera scores an asset as incomplete or stale, every downstream asset and every AI agent that depends on it inherits that signal automatically. Agents know which data to trust — and which data fails quality thresholds — before they act.

Agent outputs validated before production

Agent outputs validated before production

Context Engineering Studio auto-generates test suites from your existing dashboards and business questions, then tests agent responses against expected answers. When quality gaps cause an agent to produce wrong results — missing context, wrong numbers, answers that don't hold up — test failures surface the issue before users encounter it in production.

THE JOURNEY

Data catalogs were built for humans... who never documented them.

The First Copilot

In 2023, we launched the first AI documentation agent.

We called it Atlan AI. It could write descriptions automatically, but accuracy was at 75%. Good enough to show the vision, but not good enough to replace human work.

We Hit a Wall

We realized AI accuracy at scale needed a rebuild.

To be accurate, AI needed to access rich signals like lineage, query history, usage patterns, relationships between assets. Atlan stored all of that, but AI couldn't use it. So we rebuilt the foundation: the Context Lakehouse.

The New Reality

Today, context agents outperform humans on quality.

Customers are telling us the agent-written descriptions are more accurate and more complete than what their teams were producing manually.

Start With What Matters

Start With What Matters

Most of your catalog nobody touches. Context Agents identify your Gold Layer, Popular BI, Popular SQL, and upstream dependencies first — enriching the assets people actually use before spending cycles on the long tail. Value shows up in days, not months.

AI Scores Every Output

AI Scores Every Output

Each agent output carries a composite confidence score across accuracy, clarity, style, and completeness. High-confidence outputs auto-apply. Lower-confidence outputs route to humans.

Humans Decide & Govern

Humans Decide & Govern

AI generates descriptions, classifies assets, builds metrics, and scores quality at scale. Stewards shift from documentation to certification — sampling, validating, and resolving the cases that require judgment. One click. Not 847 manual reviews.

VALIDATE

Know your agents are producing correct answers before they ship.

Context Engineering Studio auto-generates test suites from your existing dashboards and queries — comparing agent outputs against expected answers. When quality gaps cause wrong results, test failures surface the issue before production, not after.

CONTEXT ENGINEERING & TESTING

Know when your agent is ready before your users find out it isn't.

Know when your agent is ready before your users find out it isn't.

The hardest problem in enterprise AI is knowing whether your agent works accurately in real world business scenarios and what context it's missing. Context Engineering Studio reads BI dashboards and SQL queries for context, generates 100s of questions that your AI agent needs to answer correctly, and turns those into an evaluation suite.

"With Google DataPlex, lineage only showed part of the story. Our business operates across many systems and we needed complete, enterprise-wide lineage. Atlan's platform was more intuitive, delivered on complex end-to-end lineage, and had a strong library of connectors. We also used OpenLineage for Spark jobs to tie operational lineage to our data platform."

FAQ

Frequently Asked Questions: Data Quality

What is quality context for AI agents?

circle arrow up
Quality context is what AI agents need to know whether the data they're acting on is trustworthy: is this asset complete? Is it fresh? Has it been certified? Without quality context surfaced through the context layer, agents act on data they shouldn't trust — and produce answers that fail because the underlying data failed first. Atlan surfaces quality context automatically: Vera scores every critical asset, those scores propagate along lineage, and Context Engineering Studio tests agent outputs against your existing dashboards and business questions — surfacing when quality gaps are causing agents to get things wrong.

How does Vera score data quality?

circle arrow up
Vera, Atlan's Data Quality agent, automatically scores your critical assets on completeness, accuracy, and freshness — continuously, at scale. No manual DQ rule-writing required. Vera's scores compound with governance classifications, semantic definitions, and lineage context to give every AI agent a complete picture of what they can and can't trust. High-confidence outputs auto-apply; lower-confidence cases route to human stewards for review.

How do quality scores reach AI agents automatically?

circle arrow up
Atlan propagates quality context along the lineage graph. When Vera scores an asset as stale, incomplete, or below your quality threshold, every downstream asset and every AI agent that depends on it inherits that signal automatically. AI agents querying through Atlan's MCP Server receive quality context — alongside governance and semantic context — before they act on the data.

How does Context Engineering Studio fit into data quality?

circle arrow up
Context Engineering Studio tests whether agents produce correct answers — using your existing dashboards and queries as ground truth. When quality gaps cause an agent to get things wrong (missing context, wrong numbers, answers that don't hold up against expected outputs), test failures surface the issue before production. CES doesn't inspect data freshness or completeness directly — that's Vera's job. CES validates the downstream effect: whether the agent's outputs are accurate enough to ship.

Can Atlan replace our existing data quality platform?

circle arrow up
Yes. Atlan replaces your data quality platform with the context layer for AI — Vera continuously scores every critical asset on completeness, accuracy, and freshness, and those scores propagate automatically to every downstream agent and analyst through Data Lineage. The manual rule-writing, monitoring dashboards, and human review workflows that traditional DQ platforms require are replaced by quality context that travels with your data automatically.
