How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Zenarate when monitoring customer sentiment and emerging call topics to surface compliance and experience issues matters most. Run both through a week of actual calls to see which suits your workflow.

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.
Best suited for
Zenarate is an AI simulation-training and conversation-analytics platform for contact centers, and its Performance Analyzer (formerly Call Analyzer) is the module that turns live customer calls into structured quality and coaching data. The AI engine automatically transcribes each interaction, redacts sensitive information, and scores calls against a client's defined call model and skill expectations, processing up to 100% of calls rather than a small sampled subset. Analysis runs nightly so leaders have results the next day, with automated scorecards, sentiment analysis, topic and trend reporting, and next-action coaching recommendations. Managers can drill into specific conversation moments, listen to the audio, and add commentary directly from the scorecard. Because it sits inside Zenarate's AI Coach platform, identified gaps can be turned into personalized roleplay simulations and coaching plans. It is built for QA managers, training leaders, and contact-center operations across industries such as financial services, healthcare, insurance, telecom, retail, and travel, and supports multiple languages and global deployments.
