Glass Health

AI-driven clinical decision support platform

Overview

Glass Health provides an AI-powered platform that helps clinicians generate differential diagnoses and draft clinical plans from patient summaries. The system works by combining large language models with a proprietary, peer-reviewed database maintained by physicians to ensure all suggestions are based on established medical knowledge. Unlike standard AI tools, Glass Health integrates a community library and personalized digital notebooks that allow doctors to organize and share medical insights like a "Notion for doctors." The company's goal is to reduce clinician burnout and improve patient outcomes by automating time-consuming documentation and diagnostic workflows.

Simplify's Take

What believers are saying

  • The June 15, 2026 app update signals active shipping and maintained product velocity.
  • Free Lite, Starter, Pro, and Max tiers widen bottoms-up adoption and conversion.
  • Ambient scribing plus CDS solves burnout and documentation pain across clinics and residency programs.

What critics are saying

  • Clinical error liability dominates; one bad recommendation can trigger abandonment and lawsuits.
  • OpenAI, Anthropic, and Google pressure Glass 5.5 on quality, pricing, and distribution.
  • Healthcare adoption cycles are slow; stalled EHR rollouts can cap revenue before 2027.

What makes Glass Health unique

  • Glass Health bundles differential diagnosis, assessment plans, and documentation in one workflow.
  • Glass 5.5 launched April 9, 2026, with clinical accuracy benchmarks and lower API pricing.
  • July 2026 integration pages show Epic, eClinicalWorks, athenahealth, and Elation-connected workflows.

Glass Health Is Building An Ai For Suggesting Medical Diagnoses

While a medical student at UC San Francisco, Dereck Paul grew concerned that innovation in medical software was lagging behind other sectors, like finance and aerospace. He came to believe that patients are best served when doctors are equipped with software that reflects the cutting edge of tech, and dreamed of starting a company that’d prioritize the needs of patients and doctors over hospital administrators or insurance companies.So Paul teamed up with Graham Ramsey, his friend and an engineer at Modern Fertility, the women’s’ health tech company, to launch Glass Health in 2021. Glass Health provides a notebook physicians can use to store, organize and share their approaches for diagnosing and treating conditions throughout their careers; Ramsey describes it as a “personal knowledgement management system” for learning and practicing medicine.“During the pandemic, Ramsey and I witnessed the overwhelming burdens on our healthcare system and the worsening crisis of healthcare provider burnout,” Paul said. “I experienced provider burnout firsthand as a medical student on hospital rotations and later as an internal medicine resident physician at Brigham and Women’s Hospital. Our empathy for frontline providers catalyzed us to create a company committed to fully leveraging technology to improve the practice of medicine.”Glass Health gained early traction on social media, particularly X (formerly Twitter), among physicians, nurses and physicians-in-training, and this translated to the company’s first funding tranche, a $1.5M pre-seed round led by Breyer Capital in 2022. Glass Health was then accepted into Y Combinator’s Winter 2023 batch
