How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and TwinMind when users who prefer a bot-free, privacy-conscious notetaker over tools that join the meeting matters most. Test each on your own meetings; the right choice tends to become obvious quickly.
On-device AI transcription app for Mac, iOS, and visionOS that converts lecture and meeting audio to text privately.
Browser-extension and mobile AI meeting assistant that transcribes calls in real time on-device and turns them into searchable notes.
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.

TwinMind is an AI meeting assistant delivered as a Chrome browser extension and companion mobile app that captures, transcribes, and summarizes conversations from video calls and in-person meetings. The Chrome extension works alongside Google Meet, Zoom, and Microsoft Teams to produce real-time transcripts and then generate structured notes and action items after the call. Rather than sending a separate bot participant into the meeting, TwinMind transcribes the audio playing on the user's device, so there is no visible 'recording bot' announcement. The company emphasizes a privacy-first design: the product states that audio is not stored and that only text transcripts are kept, with data saved locally and optional encrypted cloud backup. TwinMind supports a large set of languages and lets users query their past conversations through an AI chat interface, positioning itself as a personal 'second brain' for recall. It markets a single experience spanning desktop browser and phone so meetings, voice notes, and ambient conversations can be captured in one place. The product is actively maintained and operating in 2025-2026. Pricing varies by plan. Check the official website for current pricing.
