Generative BI and intelligence layers
Natural-language access to data sounds useful until the model invents a metric, joins the wrong table, or answers fluently with the wrong number.
Why common approaches fail
Chat-on-warehouse demos skip semantic contracts, groundedness gates, and ownership of metric definitions. Fluency is mistaken for correctness.
Activation insight
Natural-language access to data is dangerous when metric definitions are not controlled.
How Knackline solves it
We put an intelligence layer on trusted semantic definitions: governed metrics, groundedness checks, and agents that refuse to invent KPIs.
System components
Semantic layer contracts
Owned metric definitions the model must respect.
Groundedness gates
Stop fluent wrong numbers before they reach dashboards.
Accuracy controls
Eval sets for BI questions that matter to finance and ops.
Operator visibility
Traces of which metric and table produced an answer.
Operational hardening
Change control on the semantic layer, regression tests for BI questions, and clear refusal behavior when the catalog cannot support a query.
Evidence from reports
Generative BI as an intelligence layer: agents on a governed semantic layer
When agents invent KPIs, generative BI creates confidence without shared truth.
Semantic layer contracts for generative BI agents
A catalog that agents can ignore is documentation; a contract that agents must satisfy is governance.
Groundedness gates for generative BI: stopping fluent wrong numbers
Chat returns confident metrics that never hit the semantic layer

FAQ
- Can users still ask free-form questions?
- Yes, within the metric catalog. When a question falls outside owned definitions, the system should refuse or escalate rather than invent a KPI.
- How is this different from a text-to-SQL demo?
- Text-to-SQL optimizes for generating SQL. Generative BI must optimize for trusted metrics, auditability, and grounded answers.
