The deck is due this afternoon. You have three exports in your inbox. billing_events (31,482 rows, 2026-01-01 to 2026-06-30), customers (8,104 rows), and support_tickets (12,760 rows). A stakeholder wants a single slide that answers whether churn is rising and why.
An AI tool can draft a narrative and propose charts fast. You still own the numbers. If the churn rate in the deck is wrong, the downstream consequence is yours. The AI did not sign off on the metric definition, did not check join keys, and cannot be held accountable when Finance challenges the figure.

An LLM is a text generation model that predicts plausible next words. In analytics work, that means it produces candidate summaries and candidate steps, not validated results.
A prompt is the instruction you give the model. If you do not name the segmentation dimension, the model will usually summarize overall averages and erase the pattern you were asked to explain. That is a prompt failure with reporting consequences.
A context window is the limited amount of text the model can use at once. If you paste only the KPI table and not the metric definition, the model will confidently describe a number it does not understand.
A hallucination is fabricated content presented as fact. In a KPI deck, hallucination shows up as invented drivers, made-up definitions, or a chart description that does not match the underlying aggregation.
Tool use means the model can call external functions like a spreadsheet query or a database connector. Tool use improves access, not correctness. You still verify that filters, joins, and null handling match your intent.

AI is strong at turning already-computed outputs into clear language. You can have it draft slide titles, annotate a chart, or propose follow-up cuts like segmenting churn by plan_tier or by signup_cohort_month.
AI is also useful for surfacing candidate patterns. It can scan a summary table and flag that cancellations are concentrated in Basic plans or that ticket volume rose before churn rose. That is a hypothesis generator, not evidence.
AI is weak at truth maintenance. It does not know whether customer_id is unique in customers, whether billing_events contains backfilled rows, or whether churn is defined as “no payment in 30 days” versus “explicit cancellation.” Those are definitional and data quality questions you answer, and you own the failure mode if you skip them.
Before you share any AI-assisted statement, you verify at least one figure against the source export and you restate the metric definition in your own words. That is what makes the draft auditable.
Compare which AI outputs you can reuse directly versus what you must verify.
