The AI briefing is generated by Google Gemini. We keep the prompt deliberately narrow: the model sees aggregated numbers, not people.
What the model receives
- Department-level averages for each metric in the current period (mood, stress, sleep, energy, vibe score).
- The same averages for the previous comparable period, for delta calculations.
- Response rates per department.
- Survey question metadata — the question text itself, so the narrative can reference it.
What the model never receives
- Individual responses, names, emails, or user IDs.
- Open-text answers from surveys or journal entries.
- Raw timestamps that could identify a specific submission.
- Any data from teams with fewer than 5 responses in the period.
Why a narrow prompt matters
Passing only aggregated numbers protects anonymity even if inference traffic were ever compromised. It also keeps the output grounded — the model can't 'hallucinate' a quote from a teammate because it never had one.
Gemini's terms prohibit Google from training on your inference traffic. We also have a data-processing agreement covering this. Details in the privacy policy.
