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.

Rimo Voice is an AI transcription and meeting-minutes service developed by Rimo LLC, a Japan-based company, with a strong focus on accurate Japanese-language recognition. It is optimized for Japanese, handling kanji, katakana, punctuation, and specialized or company-specific terminology through dictionary registration, while also supporting more than 30 languages for multinational teams. Rimo Voice can join online meetings through a recording bot across Zoom, Google Meet, Microsoft Teams, and Webex, or transcribe uploaded recordings. It provides real-time, high-precision transcription, automatically generates summaries and suggested next actions, separates statements by speaker, and removes filler words such as "um" and "uh." Teams can collaboratively edit meeting minutes in real time and manage them centrally in shared folders, and the service integrates with CRM systems such as Salesforce and Microsoft Dynamics 365. On security, meeting data is stored within Japan by default (with US or EU storage available on request), and the service holds ISO 27001 and ISO 27017 certifications, with encryption, IP restrictions, and single sign-on. Rimo Voice is best for Japanese organizations and multinational teams operating in Japan that need reliable Japanese transcription and AI-generated minutes. Pricing varies by plan.
