# Essentia by BMEssentia

> Essentia is the AI built only for medical technology. It answers biomedical and clinical engineering questions from named sources: 69 devices, FDA and regulator records, and BMEssentia lessons. Made by BMEssentia (BMEssentia LLC-FZ, Dubai), founded by Hasan Khaled Ismail, a biomedical engineer.

Essentia is an AI assistant and workspace for biomedical and clinical engineers, technicians, students, clinical staff and institutions. It answers only from BMEssentia's library (123,575 passages: Platform lessons, the 69-device Device Library, Medical City lab content, 230 device model notes, FDA, MHRA, Health Canada and WHO records), cites every claim and says when it does not know. Published accuracy record (25 October 2026): 98.3% accuracy, 100% safety, red team 6 of 6. Plans: Free, and Pro at $99 a month or $899 a year. English, Arabic and Chinese.
