AirCaption

AirCaption is a desktop AI transcription and captioning app for content creators and individuals who need to turn audio and video files into accurate text and subtitles.

Key capabilities include:

• AI transcription using OpenAI Whisper, designed to work entirely offline so media and captions stay on the local computer
• Multilingual captions in up to 60 languages (website notes up to 67 languages in beta)
• Caption editing tools to adjust text and timing, plus hotkeys and playback controls for faster review
• Import and export formats for existing caption workflows, including SRT, VTT, plain text, and video exports

Pricing: Freemium, includes a free tier with unlimited transcription; paid plan is $9.99/month.

Notable for its local, no-internet-required workflow, which avoids long uploads and supports privacy-focused transcription compared with cloud-based caption generators.
