On-device AI transcription app for Mac, iOS, and visionOS that converts lecture and meeting audio to text privately.
High-accuracy automated transcription in 50+ languages
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.

Sonix is an automated transcription service that converts audio and video into accurate, searchable text across a wide range of languages. While not a meeting bot in the traditional sense, it is widely used to transcribe recorded meetings, interviews, podcasts, and videos, making it a core AI-transcription tool for teams that work with recorded conversations. Sonix provides an in-browser editor where users can review and correct transcripts, add timestamps and speaker labels, and search across content quickly. It also offers translation and subtitle features, which helps multilingual teams and content creators repurpose recordings. Because it focuses on high-quality transcription rather than live meeting assistance, Sonix is often paired with recording tools or used to process existing audio and video files. It is popular with researchers, journalists, podcasters, and businesses that need reliable transcripts they can edit, search, and translate, with an emphasis on accuracy and language coverage. Platforms: Web / upload audio and video. Integrations: Zapier, Google Drive. Pricing varies by plan. Check the official website for current pricing.
