Long video in.
Ranked clips out.
No timeline scrubbing, no guessing which bit was the good bit. Four steps, start to posted.
1Drop in a long videoA file straight off your disk, up to a couple of hours. It gets transcribed and every second scored, and a handful of clips come back — nothing is uploaded anywhere.
2Edit it right hereA real timeline in the same tab: trim, split, speed, captions, silence and filler removal, effects and stickers. No install, no upload, export when you're done.
3See them rankedEach clip gets a retention curve, not a score out of ten — the second-by-second line of who is still watching, the exact moments they'd leave, and why.
4Post the best oneBring the real numbers back afterwards and the dashboard marks the prediction against what actually happened, so the next call is a better one.Scored on your machine, just now

FAQs
Frequently asked questions
Everything people ask before they trust a clipping tool with an hour of footage.
What does it actually cost?
The editor and all six tools run on your own machine, free. Finding clips needs a transcript, and that is a paid service we call out to — so that part is metered.
Does my video get uploaded anywhere?
Your video never gets uploaded. To find clips we strip out just the audio, shrink it, and send that to be transcribed — the picture never leaves your machine. Scoring, editing, background removal, audio cleanup and export all still happen inside your browser tab.
What is the retention curve, in plain terms?
A line showing roughly what share of viewers are still watching at each second. It is a prediction, not a measurement of real viewers — it comes from a survival model that scores ten things about every second of your clip and compounds the risk of someone leaving.
How accurate is it?
Treat it as a strong second opinion, not a guarantee. It is very good at catching the specific things that make people leave — a quiet gap, a flat delivery, a static shot, a weak opening line, an outro in the middle — and at ranking your own clips against each other. It cannot know whether your topic will land.
What makes this different from a virality score?
A score is one number with no argument attached. If it says 34, you have nothing to act on. A curve says people leave at nine seconds because there is a two-second silence there, and you can fix that exact thing and watch the line move before you commit.
Which video formats work?
Anything your browser can play — MP4 and MOV cover almost everything. Exports come out as MP4 in 9:16, 1:1 or 16:9, with captions burned in if you want them.
Can I use the clips commercially?
They are your clips, cut from your footage. Cutdown claims nothing over them. If you use an AI voice or image from a third-party provider through your own key, that provider's licence applies to that piece.
Does it need a fast computer?
A reasonably modern laptop is enough. Finding clips in a 100-second source takes about a third of a second; the heavier steps are transcription and export, which scale with the length of your video and run in a background worker so the page stays usable.
Stop guessing which clip will work.
One long video in, a handful of ranked clips out — each with a plain answer to “will people actually watch this?”
