How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Voibe when writing prompts and queries into ai tools like chatgpt and claude by voice matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.
On-device AI transcription app for Mac, iOS, and visionOS that converts lecture and meeting audio to text privately.
Voibe is a private, offline AI dictation app for Apple Silicon Macs that converts speech to text on-device and inserts it into any app via a hold-to-speak hotkey.
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.
Best suited for
Voibe is a Mac dictation app that turns speech into text entirely on-device, so audio never leaves the machine. Built for Apple Silicon Macs (M1 through M4) running macOS 13 or later, it runs optimized OpenAI Whisper models locally and works with no internet connection. You hold a hotkey (such as the Fn key), speak, and release; Voibe transcribes the audio and inserts the resulting text directly into whatever app is focused. It works system-wide across Mail, Notes, browsers, Slack, VS Code, ChatGPT, Claude and other text fields, rather than in a single dedicated window. The app supports a custom dictionary for names, jargon and technical vocabulary, plus smart punctuation. Because everything is processed locally and the audio is discarded after transcription, it is positioned for professionals handling confidential or NDA-protected work, including lawyers, consultants and developers. Voibe is a voice-to-text dictation tool focused on fast, accurate, private text entry; it is not a meeting recorder or conversation-intelligence platform. A Windows version is on a waitlist.
