On-device AI transcription app for Mac, iOS, and visionOS that converts lecture and meeting audio to text privately.
Willow Voice is a system-wide AI dictation app for Mac, Windows, and iPhone that converts speech into cleaned-up, formatted text and inserts it at the cursor in any application.
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.

Willow Voice is an AI dictation tool that turns spoken words into polished written text inside any application. Instead of recording meetings, it works at the cursor: you place your cursor in a text field (such as Gmail, Slack, Notion, iMessage, or a code editor), hold a hotkey, speak naturally, and formatted text appears in place. As it transcribes, Willow automatically removes filler words, fixes punctuation, and applies formatting, and it can learn your writing style to adapt tone across different apps. The product is built for professionals who want to write messages, emails, and documents faster than typing. It runs on Mac, Windows, and iPhone, supports voice commands for inserting line breaks and bullet points, handles many languages, and offers an auto-learning dictionary for names and terminology. Willow advertises low-latency transcription and an AI mode that expands brief spoken notes into complete messages. For organizations, it markets SOC 2 and HIPAA compliance, zero data retention, and admin controls. It is a dictation tool rather than a meeting or call recorder.
