AirCaption vs Riverside

AirCaption is desktop transcription software for Mac and Windows that turns audio and video into captions, transcripts, and subtitles on your machine. It targets video editors, podcasters, marketers, and anyone who needs fast speech-to-text without uploading media to the cloud.

The app runs locally using NVIDIA Parakeet and OpenAI Whisper models, so files stay on your computer. You generate captions, review timing and text in a built-in editor, then export to SRT, VTT, plain text, or captioned video. It supports batch queueing for folder drops and works offline after setup.

AirCaption subtitles content in up to 67 languages (beta) and ships separate builds for Mac Apple Silicon, Mac Intel, and Windows with NVIDIA GPU or CPU-only options.

Riverside is a video editing and recording platform built for remote podcasts, interviews, and webinars. It records up to 4K video and uncompressed audio locally on each participant's device, so spotty internet does not tank quality. After recording, you edit in a text-based timeline, generate Magic Clips, captions, and show notes, then publish to YouTube, Spotify, and Apple Podcasts from the same workflow.

Zoom and Google Meet optimize for live calls, not post-production. Riverside records separate tracks locally, then layers AI cleanup, filler-word removal, and clip generation on top. The trade-off is that it is built for creators who publish regularly, not for one-off internal meetings that never leave the call app.

Podcasters, marketers, and producers at companies like Spotify and The New York Times use Riverside for studio-style remote recordings. Founded in 2020 by brothers Gideon and Nadav, the product now lives at riverside.com while riverside.fm redirects to the same experience.
