Ask DataHub

<FeatureAvailability saasOnly />

Ask DataHub is DataHub's conversational AI assistant that brings intelligent, context-aware help directly to where you work. Using Ask DataHub, you can ask questions about your organization's data and get instant, accurate answers grounded in both your metadata graph and your organizational knowledge—like runbooks, policies, and FAQs stored in Context Graph.

Customize Ask DataHub

As of v0.3.15, you can customize how Ask DataHub responds to queries by configuring custom instructions. These are injected into AI context to tailor the AI assistant's behavior to match your organization's specific needs, terminology, and guidelines.

Configuring Custom Instructions

To configure custom instructions:

1. Navigate to Settings > AI in your DataHub instance
2. Locate the Ask DataHub section
3. Enter your custom instructions in the Instructions field

That's it!

<p align="center"> </p>

Custom base prompts can be used to:

• Define response style and tone
• Define organization specific terminology or terms
• Guide the model on how to navigate Glossary Terms, Tags, Domains, and properties
• Guide the assistant toward specific recommendations (e.g. helping differentiate production over staging assets)

Once you've changed the custom instructions, it may take up 5 minutes to reflect in Ask DataHub.

:::tip Context Documents + Custom Instructions For organization-specific definitions, policies, and procedures, consider documenting them in Context Documents instead of (or in addition to) custom instructions. Context Documents are governable, versionable, and can be linked to specific assets—making them easier to maintain as your organization evolves. :::

Selecting a View

As of v0.3.17, you can select a View directly from the chat interface to narrow the scope of assets that Ask DataHub searches over for a given conversation. This is useful when you want to focus on a specific subset of your data ecosystem — for example, only datasets owned by your team, a particular domain, or a curated data product collection.

To select a view, click the view select dropdown next to the chat input. You can choose from your personal views or any public views shared across your organization.

<p align="center"> </p>

When a view is active, Ask DataHub will restrict its search to the datasets, dashboards, data products, domains, documents, and other assets included in that view — helping you get to the most relevant answers faster. If no view is explicitly selected, the organization's default view will be used (if one is set).

:::note Slack & Microsoft Teams When using Ask DataHub in Slack or Microsoft Teams, the organization's default view is always applied automatically. :::

How It Works

Ask DataHub leverages your complete metadata graph and organizational knowledge to provide intelligent, context-aware responses. The AI assistant considers:

• Asset names, descriptions, and documentation
• Lineage relationships (upstream and downstream)
• Ownership and domain information
• Usage patterns and popularity metrics
• Data quality and assertion results
• Tags, glossary terms, and classifications
• Schema information and sample values
• Context Documents (published runbooks, policies, FAQs, and definitions)

By combining structured metadata with unstructured organizational knowledge, Ask DataHub can answer both technical questions ("What's in this table?") and contextual questions ("How should I use this table?") with consistent, reliable answers grounded in your team's shared understanding.
