On-device AI transcription app for Mac, iOS, and visionOS that converts lecture and meeting audio to text privately.
Japanese on-premise and offline AI meeting-minutes tool from Nishika for confidential, security-sensitive organizations.
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.

SecureMemo is an AI meeting-minutes application developed by Nishika, Inc., a Japanese company, and is designed for organizations that handle confidential or sensitive meetings and cannot use cloud-based services. It runs in on-premise, closed-network, or fully offline environments, processing audio entirely within the customer's own infrastructure so that voice data never leaves the organization to an external cloud. SecureMemo is powered by Nishika's in-house speech recognition AI called "shirushi," which the company states maintains high recognition accuracy even with background noise or overlapping speech, and can transcribe audio in roughly 100 languages including Japanese, English, Chinese, and Thai. The product offers five core capabilities: accurate voice recognition, automatic speaker identification, automatic meeting-minutes generation that organizes decisions and key points, translation across about 100 languages, and custom terminology support through word registration for specialized vocabulary. The workflow follows a simple three-step process of transcription, speaker recognition, and summarization. It is offered in standalone, USB-dongle, and client-server deployment models, with case studies spanning police, government agencies, universities, manufacturers, and financial institutions. A two-week free trial of the standalone version is available. Pricing varies by plan. Check the official website for current pricing.
