Shorts is the biggest growth surface YouTube ever shipped

Your long-form audience is plateauing. Shorts is where the new subscribers are.

YouTube Shorts are showing up on the home tab, the Shorts shelf, and the For You feed of every viewer YouTube can find — and a single Short can pull thousands of cold viewers back to your long-form videos. The growth opportunity is the biggest the platform has shipped in a decade. The barrier is consistency: the algorithm wants you posting every day.

LumiClip is the YouTube to Shorts AI built for that pace. Paste any YouTube URL — long-form essay, podcast, vlog, talk — and our AI YouTube clipper picks the highest-scoring viral hooks, reframes them to vertical with speaker tracking, burns in word-level captions, and (if you want) publishes them straight to your YouTube Shorts feed.

How it works

Paste a YouTube URL. Get viral Shorts. That's it.

Three steps — drop a link, review the AI-scored hooks, publish or download. No editor, no timeline.

  1. 1. Paste your YouTube link

    Drop in any public YouTube URL — long-form video, podcast episode, conference talk, vlog. LumiClip ingests the full video and processes it without re-uploading.

  2. 2. AI clips, reframes, and captions

    Viral hook scoring picks the strongest moments, smart speaker tracking reframes to 9:16, and word-level AI captions are burned in — all in one pass.

  3. 3. Publish to YouTube Shorts directly

    Connect your channel once and publish finished Shorts straight to your YouTube account, or download MP4s sized for Shorts, Reels, and TikTok.

Core features

Built for the YouTube growth loop

Every feature points at the same outcome — more daily Shorts going out, more new viewers coming back to your long-form channel.

Viral hook scoring

AI ranks every candidate clip on hook strength, retention curve, and Shorts-feed performance signals — so the moments most likely to pop are the ones LumiClip surfaces first.

Speaker tracking and auto-reframe

Smart tracking keeps the active speaker centered as the source jumps from talking head to b-roll. The reframe stays locked even on multi-speaker podcasts and panel videos.

Word-level AI captions

Per-word, animated captions tuned for fast-paced Shorts — the kind that hold attention in the first second of a sound-off scroll. Editable inline before publishing.

Direct publishing to YouTube Shorts

Connect your YouTube channel and publish finished Shorts on a schedule, or download MP4s sized for YouTube Shorts plus TikTok and Reels in one export.

Why creators switch

Grow your channel, reach new audiences, monetize faster

LumiClip turns the back catalog you already published into a permanent top-of-funnel for new YouTube subscribers — without changing how you make long-form.

10x
More Shorts per upload

One long-form video becomes 10+ Shorts the same day it goes live — daily posting from a weekly upload schedule, finally on autopilot.

New
Audiences you weren't reaching

The Shorts feed surfaces your clips to viewers who'd never click your long-form thumbnails — every Short is a discovery moment.

Faster
Path to monetization

More published Shorts = more watch time, more subscribers, more channel signal — the metrics YouTube uses to qualify and rank you.
