Captionry vs OpenCaptions

Add captions to your videos, right on your iPhone. Captionry turns speech into captions on your device, lets you edit every line, and exports without a watermark. No account. Your video and audio stay on your phone unless you create a share link. • Automatic captions, made on your device • Two caption lines in any languages, shown in the preview and burned into the export • A timeline editor: split, move and restyle captions; 20 templates, 15 fonts, outline, background and karaoke highlight • Import up to 10 clips, reorder and trim them, and caption the combined video • Names & terms and caption rules, so names are written the way you want • Edit captions in another app with SRT or WebVTT files, then import them with a preview of every change • My Videos: your exported videos, listed and ready to share Optional AI fixes speech-to-text mistakes and translates your caption lines. Captionry asks once before you start; only caption text is sent, never video or audio, and you can switch it off in Settings. It includes 15 free video minutes each month; an optional subscription gives more. Without AI, translation runs on your iPhone. Everything else stays free.

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
