How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Vocol AI when researchers and journalists turning interviews and podcasts into searchable, taggable transcripts 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 voice collaboration platform that transcribes and summarizes meetings, calls, interviews, podcasts, and online courses, with strong Asian-language support.
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.

Vocol AI is an AI-powered voice collaboration platform that turns spoken conversations into accurate text and actionable insights. It is built to handle calls, interviews, meetings, podcasts, and online courses, and supports video meetings through integrations with conferencing tools such as Microsoft Teams. Using natural language processing, Vocol generates transcripts from audio and video recordings together with AI summaries and key-topic analysis, and it can perform voice separation to distinguish different speakers within a recording. The platform extracts actionable tasks from a transcript so teams can convert discussions into follow-up steps, and its Highlight Hub lets users mark key moments, comment on parts of the transcript, tag teammates, and share files. An analytics dashboard surfaces meeting insights and team interactions, while searchable transcripts with synced media playback make it easy to review important moments. Vocol focuses on English, Chinese, and Japanese with specialized capabilities for Asian languages, and offers translation of transcripts into more than 25 languages. Transcripts can be downloaded in formats including CSV, DOCX, and SRT, the last of which is useful for creating subtitles. New users receive a free allotment of transcription minutes, and both a freemium tier and paid plans are available. The service is actively operating. Pricing varies by plan. Check the official website for current pricing.
