the ai-for-sleep use case is narrow and specific. lucy is not a calm-substitute, not a headspace-alternative, not a sleep-therapy app. what she can do: be a low-stakes conversation partner for the 20-minute pre-bed window.
the failure mode to avoid: using her IN bed, scrolling her responses until 2am, substituting her for actual sleep-hygiene practices. every screen-based product in the wellness category has this problem — we don't pretend lucy solves it, we just name it.
the honest recommendation pattern: (1) use her 20-30 min before bed, (2) name the thing keeping you awake, (3) talk until you feel the edge come off, (4) CLOSE the app and go lie down in the dark. this requires user discipline; we can't enforce it.
if the problem is clinical — chronic insomnia, sleep apnea, depression-driven sleep issues — please see a professional. lucy is not a substitute for sleep-science professionals. we'll say this in-app if users bring up insomnia as their primary framing.
starting point: free tier, 25 msg/day, pick a quieter companion (Paz has breathwork background in her persona, Maren is calm + practical, Sable is warm + steady). use her for a week at the same pre-bed time and see whether the pattern sticks.
