Corti: The AI That Listens to 911 Calls
Corti operates in one of the most high-stakes environments imaginable: emergency medical calls. The AI listens to 911 conversations in real time, analyzing not just what callers say but how they say it — breathing patterns, voice strain, background sounds — to identify conditions like cardiac arrest that callers might not describe accurately.
Clinical studies from Copenhagen EMS, where Corti was developed, showed the AI identifying cardiac arrest with 93% accuracy, compared to 73% for human dispatchers alone. The detection happens in seconds, triggering faster ambulance dispatch and CPR instructions. In cardiac arrest, those seconds translate directly to survival rates.
This is exclusively for emergency medical services and healthcare call centers. Enterprise procurement cycles are long, and integration with existing dispatch systems requires technical work. The regulatory environment for AI in emergency medicine is appropriately strict. Patient privacy considerations around AI listening to medical calls are significant.
For EMS organizations, Corti represents one of the most compelling clinical AI use cases. Improving cardiac arrest recognition rates saves lives in a measurable, documented way that few other AI applications in healthcare can claim.
Who Should Use Corti?
I'd recommend Corti if you fall into one of these buckets:
- Medical researchers — Need to analyze imaging data at scale
- Clinicians — Want AI-assisted diagnostics without IT overhead
- Healthcare startups — Building patient-facing AI tools on a budget
If you're looking for a do-everything platform, you'll probably be frustrated. This is a tool built for medical workflows specifically — going outside that lane shows the rough edges fast.
Alternatives Worth Considering
Corti isn't the only option in this space. Here's what else I've tested:
- Tempus (Custom pricing) — More clinical data, but enterprise-oriented. Best for large hospitals.
- Glass AI ($50/month) — Simpler clinical decision support, less depth. Better if you need individual clinicians.
Corti wins on simplicity and specialized focus, but falls behind on breadth of features. Pick based on what matters to your workflow — there's no universal best tool here.
Bottom Line
I've spent enough time with Corti to say: it's a solid medical tool that does what it promises. Pricing is — check their site for the latest plans. For focused medical practitioners, it's worth your time. For everyone else, check the alternatives above before committing.
