Caption.IM

Caption.IM is a desktop application from France that provides real-time subtitles and voice input. It captures audio output from any running application, transcribes it, and displays subtitles on screen. The stated accuracy is 98 percent, and subtitles can be translated into 50 languages in real time. All audio processing happens locally using an optimized model, so the audio does not leave the device. There is a free version, a professional version at 9.9 euros per month that adds TXT, SRT, and VTT export plus speaker recognition, and an enterprise option.

- Get live subtitles for meetings, calls, podcasts, and lectures

- Professionals working across languages in conferences and negotiations

- Educators and students in multilingual courses and lectures

- Everyday users who want subtitles for foreign language video

The free version does not include the export formats, so plan on the paid tier if you need subtitle files. Local processing means performance depends on your hardware, and long sessions on a weaker machine may lag. The 98 percent accuracy figure is a developer claim and will vary with language, audio quality, and accents. Prices and feature boundaries can change, so verify current terms before you subscribe. Name and archive exported files consistently so you can find and reuse them, and keep a backup copy of key data. When quality matters, export a small draft first to confirm the result before producing the final file.
