## What is OpenCaptions?

Add animated captions to any video in a minute, and keep it private: OpenCaptions listens to your video on your iPhone, writes the words with their timing, and never sends it anywhere.

WHAT YOU GET
• Automatic captions in about 100 languages, made on your phone with Whisper
• Word-by-word highlighting, with styles from clean and quiet to loud and bold
• Your fonts: pick from the Google Fonts library
• A timeline to fix a word, move a caption or retime it
• Drag and pinch to place and size the captions right in the preview
• Save as H.264 or HEVC, with the size and frame rate you choose
• HDR videos stay HDR

PRIVATE BY DESIGN
No account. No analytics. No cloud. Your videos stay on your device. If you run your own OpenCaptions server, the app can send audio there instead, but only if you set it up.

FREE, AND PRO WHEN YOU WANT MORE
The free app has everything you need to caption a video and save it up to 1080p at 30 fps, with a small mark in the corner. Pro is a single purchase, with no subscription ever: it removes the mark and adds 4K, 60 fps, HDR, and every caption style.

OPEN SOURCE
OpenCaptions is open source (AGPL-3.0). Read the code, build it yourself, or host the web version with Docker: github.com/leogaudin/opencaptions
