Tap when sleep begins
Choose nap or night, adjust the start time only when needed, and leave the timer running.
How it works
Intelligence that begins with one tap.
Sommeil turns a lightweight shared sleep log into personalized wake-window estimates, evidence-based briefings, and AI conversations you control.
Let the model learn
Each completed session updates totals, stretches, and a personalized estimate grounded in age-aware guidance and recent history.
Share one timeline
Invite another caregiver by email. Both Google accounts see and update the same baby’s sleep history.
Personalization that earns confidence
Sommeil starts with age-based wake-window guidance. As completed sleep sessions accumulate, recent patterns contribute more to the estimate. The app shows its confidence instead of presenting a prediction as certainty.
Optional AI turns those calculated patterns into calm, plain-language briefings. The underlying prediction model remains deterministic and continues to work when AI explanations are disabled.
Available wherever questions happen
Sommeil’s private MCP server lets authorized families connect read-only sleep tools to ChatGPT as a developer-mode plugin. Ask about the last week, explore changes, or request the next sleep estimate without sharing names, notes, or raw session records.
Predictions are planning aids, not medical advice. Your baby’s cues and your pediatrician’s guidance always matter more than a clock.
