What problem it solves

Making short videos usually needs editing skills, footage and time. Grok Video Generator lets creators and marketers turn a text prompt or a single image into a short AI video clip in minutes, with the credit cost shown up front.

OpusClip is an AI video tool that automatically turns long-form videos and podcasts into short, engaging clips ready to post on TikTok, Instagram Reels, YouTube Shorts, and beyond. Creators sit on a goldmine of content inside their long videos — but manually finding the best moments, cutting them, reframing them for vertical screens, and captioning them is hours of tedious editing that most people never get around to. OpusClip collapses that entire process into minutes by using AI to do the heavy lifting, so a single long recording becomes a week's worth of short social content.

You give OpusClip a long video (or a link to one), and its AI analyses the whole thing to identify the most compelling, self-contained moments — the hooks, stories, and punchlines most likely to perform as standalone clips. It then automatically edits each one into a polished short: reframing to vertical and keeping the speaker centred, adding accurate animated captions, and even scoring each clip's viral potential so you know which to prioritise. You can review, tweak, and brand the results before publishing, and schedule them out across platforms. What would have taken an editor a full day happens almost instantly, with surprisingly good judgment about which moments actually work.

OpusClip is hugely popular with podcasters, YouTubers, coaches, marketers, and businesses that want a consistent short-form presence without hiring a dedicated video editor. Short clips are one of the most effective ways to grow an audience and feed the algorithms on every major platform, but the effort of producing them is exactly what stops most people. By automating the repurposing of content you've already made, OpusClip multiplies the reach of every long video and turns a daunting editing chore into a one-click habit. For any creator or brand trying to show up consistently in the short-form feeds that drive discovery today, it's a genuine force multiplier.
