Real-time AI meeting note-taker from Plato, strong in Korean and Japanese, with fast transcription and translation across many 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.

It captures meetings through a web browser, a desktop app for Windows and Mac, and mobile apps for iOS and Android, making it usable for both online calls and in-person conversations. The tool supports more than a dozen languages for transcription and offers real-time translation across many of them, which is useful for cross-border teams. Features include speaker diarization, one-click template generation for formatted notes, team collaboration with automatic note sharing, and an AI chat that lets users ask questions about a meeting. Tiro also integrates with calendars, CRM, and applicant-tracking systems. The vendor highlights an enterprise security posture, including a stated practice of not storing voice data for AI training, and ISO/IEC 27001:2022 certification. It is aimed at global and Korea- or Japan-centric teams. Pricing varies by plan. Check the official website for current pricing.
