AirCaption

AirCaption provides transcription for audio and video on local machines, allowing users to generate captions, transcripts, and subtitles without uploading data. It runs on the user’s device and emphasizes privacy by processing locally unless cloud features are explicitly chosen. The product targets creators and professionals who need accurate, quickly produced captions, transcripts, and translations for media content.

AirCaption guides users through a four-step workflow: generate captions with local AI models, review and edit with hotkeys, optionally translate, then save or export in multiple formats. The process is designed to run on the user’s machine, with cloud translation available as an opt-in option.

AirCaption supports multiple languages for subtitles and provides exports in SRT, VTT, plain text, or burned-in captions. It highlights privacy and offline processing, with options to import existing caption files and edit timing and text.
