Google Cloud、全データエコシステムに会話型分析機能を展開

Increasing the adoption of generative AI across the enterprise requires you to do more than deploy a generic chatbot with a custom wrapper. Interacting with business-critical databases demands absolute trust, strict governance, and deep grounding in enterprise semantics.

Over the last year, Conversational Analytics (CA) in Google Cloud has moved from isolated experiments to scaled, enterprise-wide deployments. BigQuery Conversational Analytics and the Conversational Analytics API are now generally available, adding to the general availability of Conversational Analytics in Looker last year. Building on this momentum, Conversational Analytics in Databases are also available in Preview. And so much more has happened — Google Cloud Conversational Analytics is available for more data, across more surfaces, with more enterprise controls, and greater capability than ever before.

Let’s take a deeper look at the state of Conversational Analytics in the Google Data Cloud — what you can do with it, the benefits that it brings, and how to get started with it today.

Query across multi-cloud and database workloads

Conversational Analytics is now generally available for BigQuery and Looker, and in preview for AlloyDB, Cloud SQL, and Spanner. You can also analyze data stored in Lakehouse Managed Service tables, Apache Iceberg REST catalogs, and federated AWS S3 Unity Catalogs. Whether your data resides exclusively in Google Cloud or across multiple cloud providers, your agents can query it natively.

For data practitioners, Conversational Analytics is integrated directly into BigQuery Studio, BigQuery Data Canvas, Database Studio and Data Agent Kit. For business teams, these conversational capabilities extend directly into Looker, Data Studio, and Gemini Enterprise. Data teams can publish Conversational Analytics agents created in BigQuery, Looker, AlloyDB, Spanner, and Cloud SQL directly into Gemini Enterprise, giving business leaders a centralized interface to query complex data safely.

Our APIs and MCP tools let you embed Conversational Analytics wherever your business users work, like custom applications and multi-agent systems, or as slack chatbot that can answer questions across data sources, as we showed at Google Cloud Next.

Enterprise security and governance controlsScaling generative AI to tens of thousands of users requires ironclad governance and transparent cost controls. Conversational Analytics includes Customer Managed Encryption Keys (CMEK), Private IP, and Virtual Private Cloud (VPC) controls.

We guarantee Data Residency (DRZ) at rest and machine learning processing inside multi-region endpoints within the European Union and the United States, along with HIPAA compliance. For data access, role-based controls, including parameterized secure views in AlloyDB for PostgreSQL, help ensure users chatting with an agent only see data they are authorized to view, enforced down to row- and column-level permissions.

As usage grows, administrators need tools to manage costs, observe system health, and improve accuracy. You can configure native cost controls to define limits on maximum query sizes in bytes, and track usage through BigQuery query labels and Looker system activity logs.

To maintain fleet visibility, agents can also export health, tool usage, latency, and token consumption metrics via OpenTelemetry (OTEL) standards. Integrated feedback loops allow administrators to review agent traces and user feedback, establishing a foundation for continuous evaluation and accuracy improvements over time.

Grounded context through agent and data co-designWrapping a generic LLM around an enterprise database can sometimes lead to hallucinated logic. To minimize this, we co-designed Conversational Analytics agents alongside the data platforms they query.

For instance, agents leverage Knowledge Catalog for data discovery, glossaries, and automated context enrichment like table joins and descriptions. BigQuery Graphs and Spanner Graphs allow agents to query structured and unstructured data across multi-hop relationships. Additionally, Looker’s semantic layer (LookML) grounds agent responses in centrally governed metric definitions, helping ensure answers remain deterministic rather than relying on guessed SQL joins.

Conversational Analytics agents are also co-designed with the data they query. This means their tools are context-aware, to have the best understanding of the metadata. They also benefit from built-in capabilities like multimodal data querying using BigQuery object tables, operating over multimodal data with ai.search, ai.generate_embedding, ai.classify, ai.score and using ai.forecast and ai.detect_anomalies to use the TimesFM foundation for forecasting and anomaly detection.Additionally, ai.key_drivers performs automated contribution analysis to pinpoint exactly what is driving unexpected changes in your data. When integrated with Looker, these agents leverage the semantic layer to ground their responses in centrally governed, deterministic metrics. To avoid AI hallucinations, this API-first approach (using 'Golden Queries') ensures agents retrieve verified business logic rather than guessing at SQL joins. Looker additionally equips the agents to seamlessly navigate high-cardinality datasets with dynamic filtering, automatically enforce row-level security during the chat experience, and surface context-aware suggested questions.

Proactive insights with Agentic Workflows

Analytics is moving beyond reactive question-answering toward proactive intelligence. That is, instead of requiring users to ask the right question at the right time, Conversational Analytics agents can run multidimensional deep dives to analyze 10 to 20 contributing factors behind a change in a metric.

With Agentic Workflows, now in preview, you can schedule automated reporting routines delivered directly into your chat workflow. Agents continuously run anomaly detection across key metrics, sending daily or weekly summaries straight to your team. Streaming anomaly detection can also launch an agent automatically the moment a key metric deviates from baseline thresholds.

Flexible integration with APIs, SDKs, and MCP

Conversational Analytics is available to developers and business users in their existing environments. The Conversational Analytics API includes native SDKs for Node.js, Java, Go, Python, PHP, Ruby, and .NET and keeps insights where the work happens. We are expanding how and where people use Conversational Analytics, starting with Looker Dashboards and Data Studio, as well as supporting publishing agents to Gemini Enterprise.

You can also add Conversational Analytics to other multi-agent systems. Using the Agent Development Kit (ADK) and Model Context Protocol (MCP), you can integrate Conversational Analytics into custom applications, Slack bots, or multi-agent orchestrators. For example, a supply chain orchestrator agent can query a financial data agent to calculate the margin impact of a shipping delay in real time.
