Your morning, reimagined
From 16 charts to one sentence.
We closed the gap between "I just woke up" and "I understand my CPAP data." One button — that's the whole sleep analysis interaction. No more hunting through 16 charts every morning to figure out if your sleep therapy is working.
Before — manual guessing

After — one answer
SomniDoc · plain language
Your AHI was 3.2 — well within normal range. Pressure held steady at 9.1 cmH₂O with minimal leak. You slept a solid 7h 42m. No red flags overnight.

The center of the universe
AI isn't a feature. It's the whole point.
Turn every other tile off. SomniDoc's AI sleep analysis alone will tell you if you slept well, if your CPAP pressure was right, and whether you had any apnea events worth worrying about. Everything else is optional — for the moments you want to go deeper into your CPAP data.
Want a 7, 30, 90 or 365-day therapy summary? Just ask SomniDoc.
SomniScan™ · detecting what devices miss
Sub-threshold events, caught in real time.
Your CPAP machine only scores apnea events lasting 10+ seconds — but flow reductions between 4.9s and 9.9s can still disrupt your sleep. SomniScan is the only sub-threshold analysis engine that catches them. Watch it work on real CPAP waveform data:

SomniCharts CPAP data analysis
SomniDoc reads every breath
Tells you what actually happened to your breathing. Every apnea, every hypopnea, every leak, every pressure shift — translated into plain-language sleep therapy insights.
Common questions
CPAP data analysis, answered.
How can I analyze my CPAP data online?
Upload your CPAP data card or exported files to SomniCharts and the platform reads every channel automatically, producing a plain-language summary of your night plus full 25Hz waveforms. No software install is required — it runs in your browser.
Is SomniCharts an alternative to OSCAR and SleepHQ?
Yes. SomniCharts shows the same detailed waveforms and charts that OSCAR and SleepHQ provide, but adds an AI layer — SomniDoc — that translates the data into a one-sentence summary, so you don't have to interpret 16 charts yourself. OSCAR has no AI at all, and SleepHQ's AI is limited to a paid PDF add-on, whereas SomniDoc, SomniScan, and SomniPattern run right inside SomniCharts. See the full comparison →
Which CPAP machines does SomniCharts support?
SomniCharts supports ResMed AirSense and AirCurve, Philips Respironics DreamStation and A/C-Series, Löwenstein Prisma, BMC, and Hoffrichter CPAP, APAP, and BiLevel devices. Custom importers are available for other models — email admin@somnicharts.com.
What is considered a good AHI on CPAP therapy?
As general educational information, an AHI under 5 events per hour is widely described as the normal range on therapy. SomniCharts visualizes and tracks your AHI over time, but interpretation and any treatment decisions remain with you and your healthcare provider.
Is my uploaded CPAP data kept private and secure?
Sleep data is encrypted at rest and in transit, each account is logically isolated, and SomniCharts personnel do not routinely access uploaded data. Data is automatically deleted when a membership lapses or is cancelled.
For the CPAP data nerd in you — Legacy is right there.
Still want all 16 charts like OSCAR or SleepHQ? 25Hz CPAP waveforms, flow rate, mask pressure, leak, minute ventilation, tidal volume, respiratory rate, SpO₂, period statistics — the works. Nothing we built goes away. It just moves aside for the AI-first sleep analysis view.

1
Tap any date. Every tile — AHI, Compliance, Pattern Detection, Deep Analysis — re-reads the data for that night and updates instantly.

SomniDoc regenerates its narrative for the newly selected night. The whole analysis is rewritten from scratch — new summary, new flags, new plain-language commentary.

Use the ◀ ▶ arrows on the Date tile to jump to the previous or next night with data. Months and years are pickable too — header updates the moment you click.

★ SomniDoc · 1-Year Analysis
365 nights, one narrative.
Real SomniDoc output from an actual account — 1 year of data analyzed in seconds. Watch SomniDoc narrate what you're seeing →
● Step 1 · SomniDoc
Reads 365 nights in seconds.
Every analysis paragraph you see above was generated from the raw data — no templates, no manual review.
● Step 2 · SomniPattern™
Periodic breathing, detected.
Finds breathing patterns your device ignores — often an early signal of central sleep-related issues. No one else does this.
● Step 3 · SomniScan™
Sub-threshold events, caught.
Flow reductions between 4.9 s and 9.9 s — shorter than your CPAP's scoring threshold. We surface them anyway.
