Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Vexa when streaming live, speaker-labeled transcripts into applications matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.
On-device AI transcription app for Mac, iOS, and visionOS that converts lecture and meeting audio to text privately.
API-first, open-source meeting transcription platform that deploys bots to capture real-time, speaker-labeled transcripts for developers.
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.

Vexa is an API-first, open-source meeting transcription and intelligence platform aimed primarily at developers and technical teams who want to build meeting features into their own products. Rather than being a polished end-user notetaking app, Vexa provides a developer toolkit: it deploys bots that join meetings via a URL, capture audio, and stream back real-time, speaker-diarized transcripts with low latency over WebSocket, alongside REST interfaces for programmatic bot control. Captured data can be stored and queried for retrieval and export, enabling teams to build live transcription, searchable meeting repositories, or downstream analysis on top of the platform. Vexa currently supports Google Meet and Microsoft Teams, with Zoom support indicated as planned, and its codebase is available on GitHub under an Apache 2.0 license, with both self-hosted and managed cloud deployment options. Because it exposes meeting capture and transcription as programmable infrastructure, Vexa is suited to engineering teams in areas like sales, recruiting, and other domains that need to embed meeting intelligence into custom workflows rather than rely on a standalone consumer app. It is best for developers who want control over how transcripts are captured, stored, and used. Pricing varies by plan. Check the official website for current pricing.
