Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and UserCall when triggering qualitative interviews after key in-product events 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.
AI-moderated voice user interview tool that runs qualitative discovery calls and turns transcripts into evidence-linked themes.
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.

UserCall is a qualitative research platform centered on AI-moderated voice (and text) user interviews. Researchers create a custom AI interviewer link, and the AI conducts structured one-to-one conversations using qualitative research best practices, asking adaptive follow-up questions to probe for depth that surveys typically miss. Sessions can run from a few minutes up to around 45 minutes and support 30-plus languages with customizable voices, with AI-powered translation and moderation for reaching global audiences. Interviews can be triggered automatically after key product moments such as signup, onboarding friction, upgrade hesitation, feature adoption, cancellation, or checkout abandonment, and the platform connects with analytics tools including PostHog, GA4, Mixpanel, Amplitude, and Segment. On the analysis side, UserCall converts interview transcripts into organized theme hierarchies with tagged excerpts, links conclusions back to supporting quotes, and offers an AI chat for custom exploration and pattern detection across the collected data. It is positioned for continuous discovery, voice-of-customer programs, and large-scale qualitative studies where scheduling many human-moderated sessions would be impractical. Pricing varies by plan. Check the official website for current pricing.
