Abridge is powered by its proprietary Contextual Reasoning Engine, an AI framework purpose-built for clinical accuracy and safety. The platform integrates with frontier models (including OpenAI's GPT-5.5) and applies rubric-based clinical quality evaluation and confabulation (hallucination) elimination techniques to ensure note fidelity. It operates as a full-stack intelligence layer spanning pre-visit preparation, real-time encounter capture with clinical decision support, and post-visit note finalization with coding specificity for Revenue Cycle Management. The system supports 28 languages and has powered over 100 million clinical conversations annually.
