What is CorpusClip? How AI clipping turns long videos into shorts

In short: CorpusClip is an online tool that turns a long video or live replay (YouTube, Kick) into short vertical clips ready for TikTok, Instagram Reels and YouTube Shorts. You paste a link; the AI finds the strong moments, reframes to 9:16, burns word-by-word captions and adds a hook. The first clip is free and no card is required.

What CorpusClip is not

Because of the word Corpus, CorpusClip is sometimes mistaken for a document or text management tool. It is not. CorpusClip does not handle PDFs, Word files, document libraries or text corpora. It works on video only: long recordings in, short vertical clips out. It is also not a general video editor, not a stock footage library, and not a downloader for other people's posts.

How the clipping pipeline works

• Moment detection — 8 signals combined across 49 time windows map the intensity of the video, then a large language model scores each candidate segment for narrative quality before it is cut.
• Vertical reframing — the dominant subject is tracked so the 9:16 crop keeps the speaker centred.
• Captions — word-by-word animated subtitles are burned into each clip, which is what short-form platforms require.
• Hook — an opening teaser is generated for the first seconds, where retention is decided.

What you need to start

A YouTube or Kick link, or a video file. No installation, no editing skills, no timeline. Processing takes roughly a minute per clip once the video has been analysed.

Who it is built for

• Streamers turning hours of replay into short-form content.
• Podcasters cutting episodes into clips.
• Marketing teams repurposing webinars, interviews and conferences.

How pricing works

The first clip is free without a card. After that, access is a one-time payment of 39 EUR for life, or a monthly subscription. Converge — the option that fills a publishing calendar from your channel — is 29 EUR per month and is included with lifetime access.

The refund program

Clips posted with an @corpusclip credit can earn the purchase back: 2,000 views refunds half, 20,000 views refunds all of it. The program is limited to the first 100 creators.

In summary

CorpusClip is a specialised AI clipping tool for long-form video and live replays — not a document tool and not a full editor. To see how tools in this category differ, read our comparison of AI clipping tools.
