Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Voicegain when building telephony voice bots and call analytics 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 and ASR platform with developer APIs plus a private LLM-powered meeting notetaker.
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.

Voicegain is a speech recognition company that offers both speech-to-text APIs for developers and a packaged meeting assistant called Transcribe. Its ASR engine supports batch transcription of recorded files and real-time streaming for live audio, and it can be deployed in the cloud, in a customer's virtual private cloud, or on-premises, which appeals to organizations with strict data-control or privacy requirements. On the developer side, Voicegain provides speech-to-text, speech-analytics, and telephony-bot APIs that can transcribe audio and analyze it for sentiment, named entities, topics, and intent. Its meeting product, Transcribe, is described as a private, LLM-powered meeting notetaker that captures audio from video-meeting browser tabs and uploaded recordings, integrates with Zoom, Microsoft Teams, and Google Meet, and automatically identifies topics and highlights from a conversation. A Windows desktop app supports Zoom local recordings. Because Voicegain spans both an underlying ASR platform and an end-user meeting tool, it suits teams that want either to build on its APIs or to use a ready meeting notetaker with flexible deployment and a focus on keeping data private. Pricing varies by plan. Check the official website for current pricing.
