How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and InnoCaption when making and receiving captioned phone calls independently 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.

InnoCaption is a captioning service built for deaf and hard-of-hearing users in the United States that displays real-time text of what others say during phone calls and video meetings. Users speak with their own voice and read captions generated either by live human stenographers or by automated speech recognition, switching between the two as needed. The mobile apps run on iOS and Android phones and tablets, and InnoCaption Web brings captioning to a browser. For virtual meetings, the InnoCaption Bot can join Zoom, Google Meet, Microsoft Teams, and Webex calls from a pasted meeting link, showing live captions with speaker identification; a dial-in method is also supported. Past call and meeting transcripts are saved and can be reviewed, emailed, or shared via a live-caption link that others open in any browser without logging in. The service is FCC-certified and funded through the federal Telecommunications Relay Services Fund. It is aimed at individuals with hearing loss who need accessible phone and meeting communication.
