How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Recolx when capturing lectures or interviews and turning them into structured transcripts and briefs matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

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.

Recolx is an AI voice-recording and note-taking system that pairs portable hardware devices (the Recolx Tap, Tap Pro, and AI earbuds) with a companion mobile and web app. You capture a conversation with one tap, and the platform transcribes the audio with speaker identification, then automatically produces organized notes, summaries, and "AI Briefs" surfacing key points, decisions, and action items. Transcription covers a wide range of languages, and the app adds live speech-to-text while recording plus translation features. The hardware uses a multi-microphone array with 360-degree AI noise reduction for clearer capture in noisy settings, with long continuous recording on a charge. A library of professional templates formats notes for meetings, lectures, interviews, sales calls, and legal use, and finished content can be exported to PDF, Word, or Markdown or shared to Notion, Google Docs, and Slack. It targets professionals such as attorneys, salespeople, students, and researchers who want to stay engaged in a conversation while documentation happens automatically. The app works with the hardware or with standalone recordings.
