Answer
Start with data that is already well-governed, well-understood, and useful for bounded internal assistance ... documentation, internal knowledge bases, approved report outputs, curated ticket histories, or selected operational records. Sensitive production data should only enter the workflow after governance, privacy, and retention rules are explicit.
Buyers should ask where the data lives, who owns it, what review is required, and whether the AI tool stores or reuses prompts and outputs. Data suitability matters more than model novelty.
