How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Knoi when running cross-border meetings with live korean-english translation 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.
AI meeting assistant that records, transcribes, summarizes, and translates meetings, with team organization and Q&A.
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.

Knoi is an AI meeting assistant that records meetings and converts conversations into text in real time, then automatically generates summaries, highlights, and action items the moment a meeting ends. Built by Buzzni and available as a mobile app, Knoi focuses on capturing the full flow of a discussion so users can follow along live and revisit decisions afterward. It includes real-time translation across several languages, including Korean and English, to support meetings with global teams, and it organizes meeting notes into channels by team, project, or department so past meetings can be searched with context. An AI question-and-answer feature lets users ask questions such as what was decided in a meeting and receive context-aware answers drawn from the transcript. Knoi also supports custom summary templates for outputs like weekly reports and team updates, allowing users to tailor notes to their workflow. On the security side, the product describes encryption of meeting content and ongoing system monitoring. Knoi is presented as an actively operating product aimed at teams and professionals who want automated meeting documentation, organization, and multilingual support. Pricing varies by plan.
