RedDot.ai

Ask RedDot.ai anything about your cycle. Upload a lab report, flag an anomaly, or ask why a metric moved — the assistant reasons over your encrypted data only for the length of that one question.

🔒 Disclosed transparency: plaintext leaves the sandbox over secure HTTPS only for the duration of the request to fetch answers. Nothing is saved on the AI servers.

Can you explain why my energy levels dropped on day 24 of this cycle?
RedDot.ai
Based on your logged data, Day 24 falls in your Luteal Phase (progesterone surge). A dip in energy is highly common during this transition. I noticed your sleep scale dropped to 2/5 on days 22-23, which likely amplified this effect.
