The Future of Clinical Notes: Caroline Zhang’s Journey to Simplify Medicine with AI

In a recent episode of the Delta: HealthTech Innovators podcast, host Dr. Roupen a physician, active researcher, and healthcare entrepreneur interviewed Knowtex Founder and CEO Caroline Zhang about how her company’s AI-driven solution is reimagining clinical documentation and billing. Below is a deep dive into their conversation, along with key insights for healthcare entrepreneurs looking to disrupt the status quo.

Bridging the Gap Between Technology and Patient Care

Caroline Zhang’s journey into health tech was inspired by her firsthand experience as a medical scribe. Like many clinicians, she noticed that excessive administrative work and documentation reduce valuable patient interaction time. Determined to tackle this challenge, Caroline combined her AI and policy background with her passion for healthcare. This led to the creation of Knowtex, a generative voice AI platform that streamlines note-taking and medical billing, offering clinicians a completely hands-free approach to documentation.

From Scribing to Startup

• Firsthand Understanding: By working as a medical scribe, Caroline developed a clear picture of the daily hurdles faced by physicians. This early user-centric perspective helped shape Knowtex ’s core functionality.
• Technical Expertise: With a Master’s in AI and specialization in natural language processing, Caroline identified how emerging technologies could automate and optimize workflows in ways traditional methods could not.

What is Knowtex

Knowtex uses generative AI to record clinical conversations on devices as simple as a smartphone or tablet. Once a patient visit ends, the AI automatically produces a comprehensive, specialty-specific medical note and suggests accurate billing codes. This solves several pain points simultaneously:

1. Hands-Free Documentation Knowtex transforms verbal exchanges between clinicians and patients into structured, ready-to-review notes. This drastically minimizes the need for manual transcription, saving hours of administrative time.
2. Accurate Medical Billing By parsing real-time dialogue, Knowtex identifies appropriate ICD-10, CPT, and other billing codes—even prompting for more precise codes if necessary. This reduces back-and-forth with billing staff and ensures fewer overlooked revenue opportunities.
3. Seamless Integration Knowtex can function as a standalone service or integrate with existing electronic health record (EHR) systems. This flexibility caters to both individual clinicians and large hospital networks, making widespread adoption more feasible.

Lessons from Caroline: Overcoming Challenges in Healthcare Startups

Building a MedTech startup is notoriously complex, with multifaceted challenges ranging from regulatory hurdles to user adoption. Caroline highlighted three vital considerations for healthcare entrepreneurs:

1. Stay Close to the User Immerse yourself in the clinical environment. Spend time with physicians, administrators, and even patients to identify genuine pain points that demand immediate solutions.
2. Be Patient and Persistent Healthcare systems are intricate, involving multiple stakeholders—providers, payers, administrators, and IT teams. Adoption and integration take time. Demonstrating a clear return on investment (ROI) is crucial.
3. Validate with Data Whether you’re evaluating time saved or revenue gained, offering concrete data is essential. Knowtex, for instance, quantified potential savings in physician hours and highlighted increased revenue opportunities—key metrics that appeal to hospital administrators and decision-makers.
4. Long-Term Persistence: Innovation in health tech requires patience, adaptability, and a willingness to align with evolving regulations, technologies, and payment models.
5. Focus on Impact: Remember that healthcare is about improving lives. Harness technology to elevate the human aspect of care, ensuring patients remain the priority.

A Vision for the Future of Health Tech

For Caroline Zhang and many health tech innovators, documentation is only the beginning. With generative AI handling administrative tasks, clinicians can dedicate more time to research, patient engagement, and complex decision-making. This shift could pave the way for AI-driven tools that further refine care pathways, enhance preventive medicine, and propel evidence-based practice forward.

“Technology should centralize the human element in healthcare,” Caroline emphasized. By optimizing administrative workflows, AI frees clinicians to do what they do best, care for their patients.

Conclusion The journey of Knowtex underscores how a clear understanding of clinical workflows, coupled with cutting-edge AI, can address the pressing challenges of documentation and billing in modern healthcare. For MedTech and health tech startups, this story offers valuable lessons on developing user-focused innovations, demonstrating ROI, and navigating the complexities of healthcare adoption.
