ALT A graphic for Glass Health’s Ambient Clinical Decision Support tool. The background is deep blue with flowing wave patterns. At the center is a computer interface showing two side-by-side panels: on the left, “Insights” with suggested differentials, diagnostic questions, and management recommendations; on the right, “Transcript” with a live conversation between a clinician and patient. A waveform runs along the bottom of the screen, indicating real-time audio analysis. At the top, the title reads Glass Health – Ambient Clinical Decision Support.

In medicine, customization of your AI assistant is incredibly important. Without it, you're likely to spend significant time editing AI-generated documentation drafts before they're usable in your practice/EHR.
At @GlassHealthHQ, we've made it extremely easy to teach our AI your specific practice patterns and documentation templates so you get AI generations that need minimal editing on the first try.
A bit of time invested in setting Global AI Preferences and Custom Note Templates in Glass can save you hours down the line, as you'll start to get AI outputs that are extremely close to what you would have generated yourself.
New Feature — Customization 🎉
With Customization, Glass generates AI clinical decision support and documentation that is perfectly tailored to your preferences as a clinician.
Available now at glass.health. Here's how it works🧵
