Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Otolio when sales teams preparing for and following up on client meetings matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Japanese AI meeting-minutes service (formerly Smart Scribe) that transcribes and automates the full minutes workflow for businesses.
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.

Otolio, formerly known as Smart Scribe (スマート書記), is a Japanese AI meeting-minutes service operated by Epicbase, Inc. It is designed for corporate use and automates the entire meeting documentation process rather than only producing a transcript. Users can record in-person meetings or capture audio from web conferencing tools, after which Otolio automatically transcribes the audio and generates summarized, cleaned-up minutes. Features include speaker visualization, registration of specialized terminology for improved accuracy on industry-specific vocabulary, and filler-word removal. The platform organizes recording, transcription, minutes generation, and follow-up tasks within a single interface, and offers specialized agents oriented toward meeting minutes and toward sales preparation and follow-up. Security is positioned as a core concern for Japanese enterprises: Otolio is ISO 27001 certified, uses encryption, and states that it does not perform unauthorized machine learning on user data. A mobile app supports transcription, audio playback, and file upload. Otolio is aimed at Japanese organizations that hold frequent internal meetings, sales calls, one-on-ones, and executive sessions and want to reduce the administrative burden of writing minutes. Pricing varies by plan. Check the official website for current pricing.
