The AI Sleep Companion
One system. Every signal. A clearer answer.
Not an autonomous doctor. Not a chatbot. A pattern-recognition layer over four data streams, drafted by the system, reviewed by a clinician.
AI-assisted. Clinician reviewed.
This label appears wherever AI-generated analysis is shown.
Data inputs
Four streams, read together.
Environmental
9 signals
- Light intensity and timing
- Light spectrum
- Room temperature
- Sleep-surface temperature
- Noise
- CO₂
- Air quality
- Humidity
- Scent protocol
Behavioral
9 signals
- Bedtime
- Wake time
- Daylight exposure
- Movement
- Caffeine
- Alcohol
- Meals
- Screen exposure
- Wind-down routine
Clinical and emotional
5 signals
- Intake results
- Physician notes
- Behavioral session findings
- Medication factors
- Relevant health history
AI outputs
What the system produces, and what it hands to a clinician.
- Personal Sleep Disruptor Ranking
- Night-to-night comparison
- Intervention-response map
- Plain-language explanations
- Confidence levels
- Questions requiring clinician review
- Draft Sleep Blueprint
- Home product recommendations
- 90-day adjustment suggestions
Confidence levels are shown, not hidden. Where the system cannot separate two explanations, it says so and routes the question to the reviewing clinician.
Consumer health AI
Where this connects to Health in ChatGPT.
On July 23, 2026 OpenAI launched Health in ChatGPT for U.S. users. With permission, it connects Apple Health and supported medical records so lab results, visits, sleep and activity can be read in context rather than re-explained in every conversation.
OpenAI reports that health conversations are handled by GPT-5.5 Instant on free plans and GPT-5.6 Sol on paid plans, evaluated with hundreds of physicians on HealthBench Professional, and that connected records are not used to train foundation models or target ads.
Sleep Week is built to be compatible with that shift. The measurements taken during your four days, the wearable exports and the Sleep Blueprint are structured so they can be carried into a connected assistant you already use at home, extending the program past checkout.
OpenAI, Launching Health in ChatGPT- Apple Health connection
- Supported medical records
- Sleep and activity in context
- Permission per request
- Disconnect at any time
- Not used for ad targeting
- Physician-built evaluations
- Supports, not replaces, clinicians
Medical disclaimer and safeguards
This is not medical care, diagnosis or treatment.
- The Sleep Guide and any connected consumer assistant, including Health in ChatGPT, provide general educational information only. They do not diagnose conditions, prescribe, or replace the judgment of a licensed clinician.
- Nothing here establishes a doctor, patient relationship. Every clinical conclusion in Sleep Week is reviewed by a qualified clinician before it is acted on.
- AI systems can be wrong or incomplete. Do not start, stop or change any medication, therapy or treatment based on an AI response. Confirm with your own physician.
- Connecting Apple Health or medical records to a consumer assistant is your decision, granted per request and revocable at any time. Sleep Week does not require it, and does not receive those records unless you share them deliberately.
- Suspected sleep apnea, chest pain, fainting, severe insomnia with mood symptoms, or thoughts of self-harm require in-person medical attention. In an emergency call 911 or your local emergency number. In the U.S. you can call or text 988 for crisis support.
Sleep Week is a proposed program. Descriptions of protocols, devices and partners are illustrative and are not a guarantee of clinical outcomes.
Dashboard demonstration
The interface, using clearly labeled sample data.
Three measured nights, compared with your own baseline
Night 1 is the untouched baseline. Night 2 tests the calibrated environment. Night 3 tests the complete personalized routine.
Illustrative guest data, not a medical recordBetter is higher for duration (h)
Night 1
Baseline
72°F · 1180 ppm CO₂ · 38 dB · 6 awakenings
Night 2

Improvement, deterioration and uncertainty are all shown. A three-night comparison indicates response direction; it does not establish a diagnosis.
How one input moved the next morning's result
Overnight room temperature plotted against measured awakenings across the three nights.

A visible relationship in three nights is a hypothesis to test at home, not proof of cause.
Prototype output
Personal Sleep Disruptor Ranking
The AI ranks candidate disruptors by the strength of the relationship it observed across your three nights, and states its confidence. Items needing clinical judgment are flagged for physician review rather than answered by the system.
Awakenings clustered in the first half of the night at 72°F and fell sharply at 66–67°F.
AI-assisted. Clinician reviewed. Screening indicators are never presented as a diagnosis.
Deliverable
Sleep Blueprint, preview
Sleep window
Sleep opportunity 10:45 PM – 6:15 AM; fixed wake time 6:15 AM, including weekends
Sleep surface finding
Medium-firm hybrid with active cooling layer (Surface B), fewest awakenings and highest efficiency
Follow-up
90-day tracking with review at day 30 and day 90. Breathing indicators re-checked; formal evaluation if symptoms progress.
Ranked interventions

- 02Open the bedroom to fresh air for 10 minutes before bed; verify CO₂ below 900 ppm
- 03Complete the four-step wind-down sequence starting at 9:45 PM
- 04Caffeine cutoff at 11:00 AM
- 05No alcohol within four hours of bed for the first 30 days
- 06Amber lighting only after 8:30 PM
- 0715 minutes of outdoor light within 45 minutes of waking
Physician reviewed before release. Subject to clinical review.
Hard limits
What the AI interface is never permitted to do.
The system does
- Rank your personal disruptors
- Compare night to night
- Show confidence levels
- Flag questions for clinician review
- Draft the Sleep Blueprint
The system never
- Diagnose a disorder
- Recommend prescription medication changes
- Advise stopping CPAP
- Present apnea-screening results as a diagnosis
- Handle emergency symptoms through a chatbot
- Conceal uncertainty
- Generate fabricated clinician quotes
If you are experiencing a medical emergency, call 911 or your local emergency number. Do not use any AI interface for emergency symptoms.
