Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Vatis Tech when embedding transcription into applications via the api 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.
Speech-to-text platform with developer API, speaker diarization, and meeting transcription tools.
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.

It accepts a wide range of audio and video formats and offers several export options, including TXT, DOCX, SRT, VTT, JSON, and PDF, along with a built-in editor for proofreading transcripts. Beyond transcription, Vatis Tech includes audio-intelligence capabilities such as sentiment analysis, intent detection, topic identification, and PII redaction, and it can translate transcripts into additional languages. For developers, the platform exposes a REST API with Python and JavaScript SDKs and custom-vocabulary support for domain-specific terms, while flexible deployment options include cloud and on-premises. Vatis Tech markets enterprise-grade security with GDPR compliance, ISO 27001, and SOC 2 Type II.
