Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Tana when turning meeting notes into linked tasks and project knowledge matters most. Run both through a week of actual calls to see which suits your workflow.

AI workspace with a bot-less meeting notetaker that transcribes and summarizes meetings directly into a connected knowledge base.
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.

Tana is an AI-native workspace that combines outlining, knowledge management, and a built-in meeting notetaker. Its Meeting Notetaker captures, transcribes, and summarizes meetings without requiring a bot to join the call; instead, it records computer system audio directly from the desktop app, which means it works across Zoom, Google Meet, Teams, and even in-person meetings, lectures, and interviews started on the computer. On Mac, Tana can detect when a meeting link is opened and offer to start transcribing immediately. Once captured, transcripts and summaries flow directly into the Tana workspace, where the AI can extract action items and push them to task boards, link the meeting to relevant people and projects, and surface notes where they are needed. It supports many languages with automatic detection and is available on Mac and Windows desktop apps. Tana is aimed at professionals and teams who want their meeting notes to become structured, connected knowledge rather than isolated transcripts, integrating capture with an ongoing personal or team knowledge system. Pricing varies by plan. Check the official website for current pricing.
