Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Riverside when running and documenting remote interviews or small group conversations 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.

Riverside is a web-based recording and editing studio built primarily for podcasters and video creators, with capabilities that extend to remote interviews and meetings. Participants join through a browser link without signing up, and Riverside records each person's audio and video locally on their own device before uploading the high-quality files after the session, which avoids the compression and dropout problems of standard video-call recording. Once a session is recorded or an existing file is uploaded, Riverside automatically generates a transcript using AI speech recognition, detects and labels separate speakers, and supports transcription across more than 100 languages. The transcript can be downloaded as plain text or as SRT/VTT caption files, and it powers text-based editing, where users trim or rearrange the recording by editing the transcript rather than a waveform. Riverside also offers AI clip generation for short-form social video and a teleprompter. It is aimed at podcasters, content creators, marketing teams, and anyone running recorded interviews or small group conversations that need clean transcripts and captions. Pricing varies by plan. Check the official website for current pricing.
