Best For
Practicing physicians who need fast, reliable, HIPAA-safe clinical answers and documentation support at the point of care.
2. Aidoc (aiOS + CARE Foundation Model)
Category: Medical Imaging AI & Emergency Triage
Company: Aidoc (private, global)
What It Does
Aidoc's aiOS platform embeds FDA-cleared AI algorithms into radiology and clinical imaging workflows. Its CARE (Clinical AI Reasoning Engine) foundation model, FDA-cleared in January 2026, is the first comprehensive AI triage solution of its kind.
Key Features
- 14 FDA-cleared indications (11 new + 3 existing) combined into a single triage workflow
- Detects: strokes, pulmonary embolisms, brain hemorrhages, cervical spine fractures, rib fractures, pneumothorax, aortic dissection, abdominal free air, brain aneurysms, and more
- Real-time alerts to clinical teams for urgent findings
- aiOS unifies AI across enterprise imaging systems (works across PACS, EHR, and radiology workflows)
- Powers care for 60 million+ patients per year
- FDA Breakthrough Device designation (August 2025)
Adoption
- Deployed at Advocate Health (nation's 3rd largest nonprofit health system) - expected to benefit ~63,000 patients annually
- Most FDA-cleared computer-aided detection (CAD) solutions of any vendor in the market
Strengths
- Deepest FDA-cleared imaging AI portfolio in the market
- Works in real emergency department conditions (designed for crowded EDs and imaging backlogs)
- Foundation model approach - one platform for many conditions
- Proven at scale (global deployments, major U.S. health systems)
Limitations
- Radiology/imaging focused - not a general clinical knowledge tool
- Requires integration into hospital imaging infrastructure
- Not accessible to individual clinicians without enterprise setup
Best For
Hospitals and health systems that want to reduce diagnostic delays and triage critical imaging findings faster in radiology and emergency medicine.
3. Tempus AI (Next Platform + David)
Category: Precision Medicine, Genomics & Oncology AI
Company: Tempus AI, Inc. (NASDAQ: TEM)
What It Does
Tempus combines genomic profiling, multimodal AI (imaging + genomic + clinical data), clinical trial matching, and a generative AI co-pilot (David) to support precision medicine - primarily in oncology, cardiology, and neurology.
Key Features
- Next Platform - AI-enabled precision medicine insights across oncology indications (expanded at ASCO 2026)
- xH assay - Whole-Genome Sequencing (WGS) for hematologic malignancies (launched June 2026)
- Multimodal Foundation Model - integrates genomic, transcriptomic, imaging, and clinical data for single patients
- Deep 6 AI integration (acquired 2025) - AI-powered clinical trial matching via EMR mining
- David - generative AI clinical co-pilot embedded into EHR workflows (live at Northwestern Medicine)
- 500+ petabytes of data including 45 million de-identified patient journeys, 1.5 million with sequencing data
Scale & Partnerships
- Connected to ~65% of U.S. academic medical centers and 50%+ of oncologists
- $200M deal with AstraZeneca + Pathos AI to build multimodal oncology foundation model
- Over 8 million de-identified patient records in the data platform
Strengths
- Largest proprietary oncology + genomics dataset in existence
- Only platform combining genomics, imaging, transcriptomics, and clinical data at scale
- Strong pharma/research pipeline (drug discovery, biomarker work)
- Clinical trial matching is a major differentiator
Limitations
- Primarily oncology-focused (though expanding to cardiology and neurology)
- Not a point-of-care Q&A tool for everyday clinical questions
- Full platform requires institutional/health system integration
Best For
Oncologists, academic medical centers, precision medicine programs, and pharma researchers who need genomic-guided treatment decisions and clinical trial matching.
