Kobai + Databricks Genie: Building a Fully Contextualized Chat Environment on Your Lakehouse

Databricks Genie is a powerful conversational interface. Kobai is the semantic context that makes it accurate, consistent, and scalable across the enterprise. This post explains how they work together and what changes when Genie has a shared semantic model behind it.

Databricks Genie makes it possible for business users to ask questions about Lakehouse data in natural language. It is a genuinely useful capability as it lowers the barrier to data access and reduces the dependency on analyst teams for routine data questions.

But as organizations try to scale Genie beyond a single team or data domain, a consistent challenge emerges. Each Genie space develops its own business logic. Definitions drift: “revenue” means one thing in the finance space and something slightly different in the sales space. Cross-domain questions — those that require connecting customer data with operational data, or asset data with maintenance history — break down because there is no shared semantic foundation.

This is not a Genie limitation. It is a context problem. Genie is a natural language interface; it answers questions from the data it can see and the business logic defined in its space. The challenge of scaling it is the challenge of making that context shared, governed, and consistent across the enterprise.

Databricks Genie = natural language interface to your Lakehouse data. Kobai = the shared semantic context that makes Genie accurate, consistent, and enterprise-wide.

The Genie scaling problem

Genie works well for a defined, single-domain use case: a sales team querying CRM data, an operations team querying maintenance records, a finance team querying revenue tables. In each case, the business logic is specific to the domain and the team, and it can be configured directly in the Genie space.

The challenge appears when an organization wants to do two things with Genie:

• Scale Genie across multiple business units, so different teams can ask questions about different domains from the same Lakehouse
• Enable cross-domain questions — questions that span operations and finance, or customers and supply chain, or assets and workforce — that require connected context to answer correctly

Both of these require a shared semantic foundation. Without one, scaling Genie produces a proliferation of spaces, each with its own business logic, each answering the same concepts differently. When a user asks a cross-domain question, the context boundary of a single space is not enough to answer it.

What Kobai adds: a shared semantic foundation for Genie

Kobai provides the semantic layer that Genie draws from. Rather than each Genie space defining its own business logic, the enterprise’s shared concepts (entities, relationships, terminology, and rules) are defined once in Kobai’s semantic model and made available to every Genie space built on top.

The integration is direct. With a single line of code in the Kobai SDK, a Genie space is connected to the semantic model. Genie then queries semantic views — governed projections of the knowledge graph — rather than raw Delta tables. The answers Genie produces are grounded in the shared definition of what each entity means and how it relates to others.

That single call creates a Genie space backed by the full semantic context of the operations domain — entities, relationships, query views, and ontology metadata — all governed by Unity Catalog, all executing on Databricks compute.

What changes when Genie has a shared semantic model Genie answers become consistent across teams

When “revenue,” “customer,” and “active asset” are defined once in the semantic model, every Genie space that draws from that model uses the same definitions. A finance team and a sales team asking the same question get the same answer because they are querying the same semantic ground truth, not independently configured space logic.

Cross-domain questions become answerable

Because the semantic model connects entities across domains — assets to maintenance events to engineers to operational schedules, or customers to contracts to products to support history — Genie can traverse those connections to answer questions that a single-domain space cannot. The question “what is the projected revenue impact if the turbine maintenance on Site B extends beyond the planned window?” requires connecting assets, maintenance, operational schedule, and revenue data. With a connected semantic model, Genie can answer it.

Genie scales without rebuilding context

Each new team or business unit that needs a Genie space connects to the appropriate Domain Room of the shared semantic model, rather than defining business logic from scratch. The configuration overhead that would otherwise compound with every new space is reduced to a declaration of which domain context is relevant. The semantic model is maintained centrally, by the domain experts who own each area, and evolves as the business evolves.

AI answers carry explainable lineage

Genie answers grounded in a Kobai semantic model are traceable. Every answer can be resolved back through the semantic query to the specific entities, relationships, and data records that produced it. For teams in regulated environments or simply for teams that want to trust the answers they are acting on, this traceability is the difference between a tool they use cautiously and one they rely on.

Genie gives your teams natural language access to Lakehouse data. Kobai gives Genie the shared business context needed to make that access accurate, consistent, and explainable at enterprise scale.

What this looks like in practice How the Kobai + Genie architecture works

The Kobai + Genie architecture is additive. Genie remains unchanged. Kobai adds the semantic layer on top of the Databricks Lakehouse, and Genie connects to it through semantic views published by the Kobai SDK.

The key architectural property is that the semantic model is the shared asset — defined once, maintained by domain experts, and consumed by every Genie space, AI agent, or analytics tool that connects to it. When the model is updated, every connected Genie space reflects the change. There is no per-space business logic to keep in sync.

Genie without Kobai vs Genie with Kobai GETTING STARTED Starting with the Genie Spaces Accelerator Kit

Kobai’s Genie Spaces Accelerator Kit is available on the Databricks Marketplace and provides a structured path to deploying a shared semantic foundation for Genie within an existing Databricks environment.

• Define a shared semantic model for a focused starting domain — typically a domain where multiple teams are using Genie and definition drift is already causing problems
• Connect 1–2 Genie spaces to the semantic model using the Kobai SDK
• Demonstrate cross-domain question capability on a live dataset before expanding to additional domains
• Expand incrementally: each new Domain Room connected makes every existing space richer through the network effects of shared entities

The typical path from environment setup to a working multi-domain Genie space grounded in a shared semantic model is measured in weeks, not months. The Kobai team supports the semantic modelling process and the Genie space connection — domain experts author the ontology, engineers handle the data connections.

Genie at enterprise scale starts with shared context

The organizations that get the most from Genie are not the ones with the most spaces. They are the ones where every Genie space draws from a shared, governed, semantically rich understanding of the enterprise — one that reflects how the business actually thinks about its entities, relationships, and rules.

Kobai provides that foundation on the Databricks Lakehouse. The semantic model is built by domain experts, governed by Unity Catalog, and made available to Genie through a single SDK integration. Cross-domain questions become answerable. Definitions stay consistent. AI answers carry explainable lineage. And every new Genie space added to the enterprise makes the shared model more valuable, not more expensive to maintain.
