Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and HeyMarvin when product teams clustering interview feedback into shareable themes matters most. Run both through a week of actual calls to see which suits your workflow.

AI research assistant that records and transcribes user-research interviews and builds a searchable insights repository.
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.

HeyMarvin (Marvin) is an AI-native customer insights platform aimed at user-research and product teams, with the research interview as its central meeting type. During live user-research calls it records sessions, transcribes them automatically, and lets researchers capture time-stamped notes and highlights, including collaborative live note-taking with teammates. After the session, its AI workflows distill feedback into themes and patterns, and an Ask AI feature lets teams query their data and get answers with citations back to the source clips. Everything feeds a centralized, searchable research repository that brings qualitative and quantitative inputs together from many sources, so insights are not scattered across documents and recordings. The platform also offers AI-moderated interviews in multiple languages, video clips and curated playlists for sharing findings, and integrations with tools used to distribute insights. It includes privacy and security features such as PII redaction and enterprise compliance. For a meeting-tools directory, its relevance is the combination of interview capture, AI notetaking, and a repository tuned for analyzing user-research conversations rather than general meetings. Pricing varies by plan. Check the official website for current pricing.
