An AI-first electronic health record
Self-hosted, FHIR R5 native, with AI built into documentation, coding and drug-interaction checks. Modules switch on per clinic and specialty, from a home practice to a hospital network.
A company operating system with an AI layer
Intranet, HR, expenses, contracts and records in one self-hosted product. Agents work through the same API as people, and nothing they propose happens until a person confirms it.
Live audience feedback for speakers
Listeners tap green or red while they listen; each tap lands on the sentence being spoken. Live captions and Q&A during the talk, highlight clips and a recap after it.
A CRM for pharma field and medical teams
AI-first, works offline, headless: a rep dictates for twenty seconds and gets a structured call report. Self-hostable and air-gappable, an open alternative to Veeva CRM.
Self-hosted customer engagement for websites
Live chat, an AI answer bot that cites your help articles, one inbox for chat, e-mail, messengers and phone, and cases with a pharmacovigilance pack. On your servers, nothing calling home.
The pharma field CRM, hosted at crm.yeysus.com
The same AI-first, offline-capable CRM, run as a service: sign up and start, no server of your own.
