AI Tools for Video Captions

Video captions are text overlays of spoken dialog. Captions drive retention, learning, accessibility, and engagement. They also provide text for search engine bots, elevating rankings.

YouTube generates captions automatically when requested by a viewer, but they aren’t edited and don’t otherwise emphasize the key points. Social media videos are silent — without captions, viewers may not understand a video and thus scroll past it.

Video captions used to take a lot of time, but with AI the task is automated. Here are three AI-driven tools to produce engaging video captions.

Klap automatically breaks long videos into short episodes, each with captions. It’s handy for publishing on Instagram and TikTok.

Each episode can be shortened or lengthened, but the initial versions required minimum editing in my testing. Klap assigns a “variety” score to each episode — an estimate of its social media shares.

Pricing for Klap starts at $29 per month for 10 videos of 45 minutes each and 100 clips.
