Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and TransDyne when clinics converting recorded dictations into structured ehr reports matters most. Test each on your own meetings; the right choice tends to become obvious quickly.
On-device AI transcription app for Mac, iOS, and visionOS that converts lecture and meeting audio to text privately.
TransDyne is a healthcare documentation service that uses a human-AI hybrid model to transcribe patient encounters and dictations into structured EHR notes.
Aiko is a native transcription app for macOS, iOS, and visionOS, developed by Sindre Sorhus, that converts speech to text from meetings, lectures, and recordings entirely on-device. It uses OpenAI's Whisper model running locally, so audio never leaves the user's device, which makes it appealing for students and professionals with privacy requirements. Aiko transcribes both audio and video files in common formats such as .m4a, .wav, .mp3, .mp4, and .mov, and supports around 100 languages. Transcriptions can be exported in multiple formats, including JSON, CSV, and SRT subtitles, and the app includes a word-replacement feature to automatically correct recurring errors. It also integrates with Apple Shortcuts for automation workflows. Because Aiko prioritizes accuracy over speed, it does not perform live transcription while recording and currently does not include speaker detection, so it is best for transcribing recorded lectures, interviews, and meetings after the fact. The app is offered as a Universal Purchase with a free trial via TestFlight, making it a low-cost, privacy-first option for turning lecture and meeting recordings into searchable text. 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.
