Model explainability in healthcare matters

In healthcare, model reasoning paths carry high-stakes implications. Understanding how a model reaches its conclusions is essential for safety, compliance, and trust.

To advance this, Corti’s research team developed the Generative Interpretability Method (GIM), marking a major step forward in mechanistic interpretability.

Across leading architectures like Gemma, LLaMA, and Qwen, GIM achieves over 2× higher faithfulness than existing methods, enabling Corti to build more transparent, auditable, and trustworthy AI infrastructure for high-stakes environments.

Read our research
Bar chart of faithfulness scores: GIM from Corti scores 2.24 on GPT-2, 2.02 on Qwen-2.5, 3.54 on Gemma-2 and 2.54 on Llama-3.1, against 1.10, 0.80, 1.33 and 0.90 for existing methods

Clinical documentation generation tailored to every workflow

Generate accurate clinical notes

Turn transcripts, structured data, or past records into polished documentation automatically. Corti creates SOAP notes, discharge summaries, and follow-up letters in seconds, cutting manual work while ensuring accuracy, consistency, and compliance.

Real-time, ready-to-sign drafts

Generate full drafts seconds after the encounter ends. Clinicians simply review, edit, and sign, reducing hours of admin to minutes without disrupting workflow or accuracy.

Flexible, custom templates

Select from our library of clinical templates or define your own with custom sections, terminology, and style. We provide modular and flexible infrastructure, enabling documentation tailored to your users’ specialties and standards.

Multiple outputs from one encounter

Produce different documents from the same interaction: a clinician note for the EHR, a patient summary, and a billing-ready report - all from the same source.

Multilingual documentation at scale

Generate medical documentation in English, Danish, Spanish, German, French, Swedish, and more. Corti is the trusted foundation for teams building clinician and patient-facing applications with precise multilingual documentation needs.

What will you build?

Patient summaries

Generate patient-facing handouts in plain language, directly from the same interaction used to create the clinical note.

Clinical notes

Turn conversations into structured SOAP notes, discharge summaries, H&Ps, or ER reports with clean formatting and no manual typing.

Referral letters

Use specialty-specific templates to auto-generate referral notes, follow-ups, or nursing documentation in your format.

Multi-language output

Generate both a professional note and a patient summary - each in a different language from a single transcript or fact.
