Bold word-by-word captions, free and open source

Short-form video has a house style: heavy capitals, a few words at a time, the word being said lit up in a colour. People often search for it as “Hormozi-style” captions. OpenCaptions makes that look from your own video, in a few steps, with an open-source editor you can run yourself.

How to make them

1. Add your video and transcribe it. Every word gets its own timing.
2. Pick a look. Bold is heavy type with each word popping as it is said. Purple Punch slides a coloured box from word to word. Karaoke sweeps colour across each word. Boom bounces big words in a display font.
3. Set how many words show at once, and move the caption with your finger or the mouse.
4. Fix any misheard word on the video, then save.

Every look is a starting point: the style panel changes the font, the colours, the outline, the animation and the timing.

What it costs

The web editor is free to self-host, with every look. In the iPhone app Bold, Purple Punch, Karaoke, Paper and Plain are free, up to 1080p at 30 fps with a small mark. Pro is one purchase, with no subscription.
