AudioDiary is an AI-powered voice journaling app that records spoken entries, transcribes them, and generates summaries and reflective insights.
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.

AudioDiary, made by Soliloquy Apps Limited, is a voice journaling application that lets users capture thoughts by speaking instead of typing. Users record an audio entry and the app automatically transcribes it and applies AI to produce summaries, reflections, suggested goals, mood tracking, and pattern visualization over time. It also offers dream analysis, custom tagging, themes, and the ability to attach photos to entries. Captured content can be exported as audio, transcripts, images, or PDF, and entries can be edited after recording. Its "Session Designer" lets users personalize or disable AI features, and extracted goals can sync to Google Calendar. The app is available across iOS, iPad, Mac (including Apple Vision), and the web, with synchronization between platforms. Recordings are encrypted in transit and at rest, with data stored via established cloud providers, and the company states it does not sell or monetize journal entries. It is aimed at individuals seeking a reflective, spoken personal journaling and self-tracking habit rather than business meetings.
