Instant AI Video Editor

Edit videos at the
speed of scroll

Word-perfect captions, one-click silence cuts, auto reframe, and an AI co-editor, all in a tab. Your footage never leaves your device.

Meet the new cut

Fast tools, built for the feed.

1/6

Word-level everything

Captions, silence cuts and edits all key off the same word-accurate transcript, so what you see is what was said.

2/6

Local-first by design

Projects live in your browser and rendering happens on your device. Privacy isn't a setting here. It's the architecture.

3/6

Undo you can trust

Every operation, even a whole AI request, lands as one step in history. Experiment freely; one press brings you home.

4/6

Hardware-fast export

WebCodecs talks straight to your machine's encoder. A 17-second vertical renders in about 40 seconds, up to 4K60.

5/6

Open where it counts

Built on the MIT-licensed OpenReel editor, with our fork public on GitHub. Stand on open source, give back to it.

6/6

An editor that listens

The AI co-editor speaks timeline: it splits, trims, styles and stacks with the same tools you'd use by hand.

The boring parts, on one click

Captions that hit every word

One click transcribes your clip and lays styled captions on the timeline, each word highlighted exactly as it's spoken. Eight looks, and the animation survives export.

  • Word-level timing, not guessed timing
  • Stacked · Minimal · Serif · Punch · Karaoke Pop · Neon · Typewriter · Soft
  • Every caption stays editable text

Dead air, deleted

flshy scans your clip for silences and shows exactly what it found, and how much time you get back, before a single cut happens. Snapped to word boundaries so it never clips a syllable.

  • Preview every cut before you commit
  • “Remove 12 silences · saves 2m 14s”
  • One undo reverses the whole pass

One shoot, every ratio

Turn a landscape master into vertical, square and 4:5 without losing the subject: face and object tracking keeps them centered while the crop moves smoothly around them.

  • 16:9 · 9:16 · 1:1 · 4:5 · 4:3 presets
  • Subject tracking, not center-cropping
  • Crops become editable keyframes

“Make a 15-second teaser”

Tell the editor what you want. It cuts, captions, reframes and grades. Every request lands as one undoable step, and nothing destructive happens without asking first.

  • Plain language in, timeline operations out
  • One click undoes an entire request
  • Destructive changes always confirm first

flshy is for people who'd rather be posting than exporting. If you've ever nudged a caption frame by frame at 2am, this one's for you.
