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.

Fast Rekap (also branded FastRekap AI) is an iOS application that records meetings, lectures, and voice memos, transcribes them into text, and instantly generates structured outputs. Beyond a standard transcript, the app produces concise AI summaries that highlight key decisions and action items, and it can automatically convert the captured content into presentation slide decks and visual mind maps, which sets it apart from notetakers that produce only text notes. A smart Q&A feature lets users chat with a transcript and receive context-aware answers based on the meeting content. Notes are saved, searchable, and shareable, with PDF export and automatic email delivery of summaries and full transcripts after each recording. The app supports a wide range of languages (the listing cites support across many languages including Spanish, French, German, Chinese, Japanese, Korean, Arabic, Russian, and Vietnamese). Fast Rekap was first released in September 2025 and is actively updated, available on the Apple App Store for iPhone. It targets professionals, students, and anyone who needs to turn spoken sessions into organized, presentable documentation quickly. Pricing varies by plan. Check the official website for current pricing.
