Once you find a clip you want to share, you can snip up to 30 seconds of it and generate a captioned video clip, then share it to your social media app of choice. People are more likely to watch a captioned clip, as they can do so without the need to listen to the audio in a quiet environment. One drawback is that the captions are auto-generated, so quality could be spotty at best.

The app is mostly aimed at consumers, unlike Spotify's short-form podcasting app Anchor, which can also generate captioned snippets. Another product with similar features, Headliner, also mainly targets producers.

Bullet works on top of any iOS podcast app, including Apple Podcasts and Spotify, which together account for 72 percent of usage. "People quickly skim over news articles, tweets and Facebook posts to determine if they want to continue reading," said Bullet CEO Benjamin Lim. "There is no easy way to do the same for podcasts, which is why new podcasts are so hard to discover. We want to change that." ​
