Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and TORTUS when transcribing and documenting telephone triage and clinical hub calls matters most. Run both through a week of actual calls to see which suits your workflow.
On-device AI transcription app for Mac, iOS, and visionOS that converts lecture and meeting audio to text privately.
TORTUS is an ambient AI clinical assistant that listens to patient consultations and automatically transcribes them into structured clinical notes, letters, and coding suggestions.
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.

TORTUS is a regulated, healthcare-specific ambient voice AI built with the NHS. It acts as an AI scribe that listens to clinician-patient consultations, transcribes the conversation using speaker-diarized speech-to-text, and uses large language models to draft structured clinical notes, referral letters, patient summaries, and suggested clinical coding (including SNOMED) within seconds for clinician review. Audio is captured with on-device, locally encrypted processing, and the company states no patient audio is retained at rest. The platform supports both face-to-face and telephone consultations, with telephony integrations such as X-on Surgery Connect and Avaya. It integrates with major electronic health record systems including Epic, EMIS Health, TPP SystmOne, Oracle Health, Access Rio, and Medicus to enable clinician-approved write-back. It is registered as a UK Class I medical device and holds ISO 13485, ISO 27001, and Cyber Essentials Plus certifications. TORTUS is aimed at clinicians and healthcare organizations such as NHS Trusts, hospitals, ambulance services, outpatient clinics, and GP practices. The company reports use across more than 2.5 million consultations.
