Arintra vs Penguin Ai

Arintra is the narrower, provider-side platform built around coding, with autonomous coding written back to the EHR, HITRUST e1 certification and a Series B announced in August 2026. The vendor names Mercy Health, UC Davis Health (an audit "approximately 50% faster", per the vendor) and Vanova Health on athenahealth. For a health system coding director comparing references, Penguin Ai is the thinner choice: Arintra's homepage names customers and Penguin Ai's homepage and about page do not.

Penguin Ai, founded in 2024, is a wider platform. HCC Coding and Risk Adjustment sits beside prior authorization review for payers and an RCM loop, and the company lists Epic FHIR and Cerner. The vendor reports 96% accuracy and 92% of cases resolved without a human touch and cites no study, and it frames its output as a recommendation. A health plan or risk adjustment group wanting one agent platform across utilization management and HCC is the buyer.
