📸 9:16 for Reels, 4:5 and 1:1 for the grid

Turn YouTube Uploads Into
Captioned Reels

AI reads the transcript and picks the moments worth posting, then cuts them to 1080x1920 with captions burned in. Switch a clip to 4:5 or 1:1 when it belongs in the grid instead. First clip free.

Built for Instagram

Reels and the grid want different shapes. One source can serve both.

Instagram is not one surface. Reels is vertical and lives on the reels tab; the feed still rewards 4:5; a square crop is what fits a carousel slot. Producing for all three usually means going back to the edit three times, which is why most creators produce for one and let the others go.

GhostShorts processes the source once. The transcript is read for the passages that work standing alone, each is cut on real word boundaries, and from there the ratio is a setting rather than a re-edit — 9:16, 4:5, 1:1, or the original 16:9, each rendering at its own 1080-class size.

Captions do the rest of the work. The feed autoplays muted, so word-synced captions burned into the file are not decoration, they are the difference between someone reading the clip and someone scrolling past it.

  • 1080x1920 for Reels, plus 4:5 and 1:1 for feed and carousel
  • Clips run twenty to ninety seconds, inside Reels’ comfortable range
  • Word-synced captions in seventeen styles, burned in for muted autoplay
  • Fix a mistranscribed word in place without breaking caption timing
  • No watermark on any export, at any ratio

Three shapes, one process

Ratio is a per-clip setting in the editor, not a separate render job you have to plan for. The same processed source serves Reels, the feed, and a carousel.

Captions as the hook

Word-synced with the active word highlighted, in seventeen styles, burned into the file so they survive Instagram’s re-encode.

Nothing posts itself

No account connection and no scheduler. You download the files and upload them, which means nothing can go out under your handle unless you send it.

Crop you actually control

No automatic subject tracking here, and we will not pretend otherwise. Full or fit, a focal point, or a crop rectangle — set once, held for the clip.

Made a Reddit story short in the middle of my chem class. 100K views before I got home.

Honestly thought this was just another overhyped AI tool. But it actually delivers and is super easy to use. I already created 10 shorts in 1 day.

Tried a couple viral formats on the app. A month later... 10 million views. This app is stupid easy to use.

Making edits CapCut felt homeworkish. GhostShorts is easy af, almost feels likes I am on autopilot.

All I do is copy a Reddit post, paste it in, export, done. It's stupid easy.

I run a few fake text story channels. Jesus I've hit over 5 million likes on just one of my channels alone. It's ridiculous.

Vertical clips export at 1080x1920, which is exactly what Reels wants. In the editor you can also switch a clip to 4:5 or 1:1 for a feed post, or 16:9 if you want the original shape, and each renders at its own 1080-class size.
Each one runs between twenty and ninety seconds, which sits comfortably inside Reels. If you want something tighter for a particular post, trim it in the editor before rendering.
No. There is no Instagram account connection, no scheduling, and no auto-posting. You download finished MP4 files and upload them yourself.
The files GhostShorts exports carry no watermark of any kind. What Instagram does with content that visibly originated elsewhere is its own call and changes over time — but nothing is stamped on the clip from our side.
On a feed that autoplays muted, they are most of the clip. Captions here are word-synced with the active word highlighted, come in seventeen styles, and are burned into the file so they survive upload and re-encoding. You can also fix a mistranscribed word without breaking the timing.
It reads the transcript. An AI goes through the whole thing looking for passages that stand alone — an opening worth stopping for, one idea held, a clean ending — and cuts each one on real word boundaries. It does not analyse the picture.
By setting it. There is no face detection or automatic reframing, so the crop stays where you put it: full or fit, a focal point you drag, or a rectangle you draw. For a centred talking-head source that is one setting for the whole batch; for a busy multi-camera edit, expect to adjust per clip.
One clip per video: the strongest moment from the first six minutes of your own upload, cut and captioned, playing in your browser. No card required. Processing the whole video is the paid step.
