Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and UserBit when tagging and coding interview transcripts to synthesize insights across a study matters most. Try them side by side on real calls before deciding — needs vary by team.

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.

UserBit is a qualitative user-research platform for product, design, and UX teams, agencies, and freelancers. Users upload audio or video recordings of user interviews, and UserBit's AI generates transcripts in many languages, automatically splitting the text by speaker. A companion video player stays synced to the transcript, so scrolling the text moves the recording and clicking the video seek bar jumps to the matching words. Researchers can add custom vocabulary to improve accuracy and edit transcripts inline. Beyond transcription, the platform manages interview participants, questions, and responses, and lets teams capture qualitative notes and files. Tagging a portion of a transcript automatically creates a video clip of that moment, and a taxonomy/coding system supports synthesis. Analysis tools include charts and correlation maps to surface insights, and UserBit also offers journey-mapping and persona-building modules. It is web-based and centralizes the full research workflow from raw interviews to shareable findings in a single repository.
