TransDyne is a healthcare documentation service that uses a human-AI hybrid model to transcribe patient encounters and dictations into structured EHR notes.
Alter is a native macOS application that records, transcribes, and analyzes meetings directly on the user's Mac without sending a bot into the call. Instead of joining a meeting as a visible participant, Alter captures audio from the system output and microphone, so it works across Zoom, Microsoft Teams, Google Meet, WhatsApp, FaceTime, Skype, Discord, and in-person conversations. Transcription runs through on-device models, with a choice of an optimized Parakeet model for major languages or Whisper for broader language coverage, and speaker identification is performed locally. Because processing happens on the device, recordings and transcripts stay on the Mac and the app can operate without an internet connection. Beyond raw transcripts, Alter generates summaries and action items, lets users chat with their meetings, and connects to tools such as Notion, Slack, Linear, Asana, and Jira. It targets solopreneurs, freelancers, consultants, and other professionals who want private, bot-free meeting capture on macOS. The product is actively developed and operating in 2025 and 2026. Pricing varies by plan. Check the official website for current pricing.

TransDyne is a US-based healthcare technology company offering AI-assisted virtual medical scribe and medical transcription services for clinicians. Its core product captures patient-provider conversations and dictations, then turns them into structured, EHR-ready clinical documentation. Audio is captured several ways: ambient microphones that listen during the live patient encounter, a toll-free phone-in dictation system, Android and iOS mobile dictation apps, and uploads from digital recorders. TransDyne uses a "human-AI hybrid" workflow in which AI generates an initial draft and a trained remote scribe reviews and corrects it before it reaches the chart, aiming for accurate, medically coded notes rather than raw transcripts. Completed documentation integrates with major EHR/EMR platforms such as Epic, Cerner, and Athenahealth via HL7 messaging and secure connections, and the service is marketed as HIPAA-compliant. The company also provides related services including medical-legal record review, revenue cycle management, and telemedicine support. It is aimed at physicians, clinics, and healthcare practices seeking to reduce documentation burden and physician burnout.
