Everything it does, and what it deliberately does not
Each of these is a switch. You turn on what this video needs and leave the rest alone — nothing is applied without you turning it on.
The list below is the whole product. There is no hidden pro tier on this page.
Cutting pauses is free and needs no account.
How it works
This is what happens the moment you open a recording, before you decide anything.
What you get
Every one of these is a switch. Turn on what this video needs and leave the rest alone.
Pauses cut automatically
Silence, hesitation and dead air are removed in the browser, before anything is uploaded. Free, no account.
The AI reads what was said
False starts, repeated lines and off-script chatter are flagged one by one, for you to approve or keep.
Captions from the speech
Already in sync, with ready-made styles and a screen to fix proper nouns before export.
Reframing that follows the face
16:9, 9:16, 4:5 and 1:1 from one recording. The crop tracks whoever is speaking, one framing per take.
Colour measured on your footage
White balance, levels and contrast from your own material, plus looks. Two cameras are matched to each other first.
Voice levelled and cleaned
Noise reduced, every scene brought to the same loudness, peaks held under the ceiling you choose.
Soundtrack that ducks under you
Generated to the length of your edit, dropping on its own while you speak.
Person separated from background
Blur it or push it back so the speaker comes forward. The desktop app uses a heavier model for this.
Name bar, highlight and end card
Lower third, one sentence in focus and a closing card with your logo — placed on the preview itself.
Hand it to a real editor
Export the timeline as XML/EDL/SRT for Premiere, Final Cut and DaVinci — with the reframing, a .cube of the grade, and the person matte.
Your video never leaves
The file is read straight from your computer. Only the audio goes out, and only when you ask for captions or take selection.
A desktop app for long material
No duration ceiling, a heavier background model and a stronger colour pass — the render writes to disk.
And what it does not do
Stated here so you find out now and not after you have recorded.
Up to 30 minutes per project
In the browser. The ceiling is memory during export, not a plan — the desktop app has none.
Firefox writes WebM, not MP4
It opens on a computer and on YouTube, but Instagram and TikTok tend to refuse it. Export from Chrome, Edge or Safari for those.
Export needs a free account
Cutting pauses does not. Five videos a month while the beta lasts, because captions and take selection use a server.
No multi-track timeline
On purpose. This is for people who record, not for people who edit — if you need layers, export the timeline to Premiere or DaVinci.
Questions
The ones people ask before trying it.
What is NinjaClip?
NinjaClip is an AI-powered automatic video editor that turns raw footage into a polished, ready-to-publish video: it cuts the pauses, picks the good takes, writes the captions, reframes the speaker and corrects the colour. It runs in your browser, and there is also a desktop app for long material.
What does NinjaClip do?
It removes silence and hesitation, reads the transcript to flag false starts and repeated lines, generates captions in sync, reframes 16:9 footage to 9:16, 4:5 or 1:1 following the speaker, levels the voice, corrects colour, adds a soundtrack that ducks under speech, and exports the finished video or a timeline for Premiere, Final Cut and DaVinci.
Does NinjaClip work in the browser?
Yes. Editing runs entirely in the browser and your video file is read straight from your computer — it is never uploaded. Producing the final file works in Chrome, Edge, Safari and Firefox; Firefox writes WebM instead of MP4.
Is NinjaClip free?
Cutting pauses is free and needs no account. Captions, take selection, soundtrack and export need a free account, because they use a server — five videos a month while the beta lasts.
How long can the video be?
Up to 30 minutes of combined footage per project in the browser — the ceiling is the browser's memory during export, not a plan limit. The desktop app has no ceiling.
What files can I open?
Whatever your browser opens: MP4 and MOV in H.264 or HEVC, and WebM. You can drop several files at once and they become one video, in the order you picked them.
Does it work in languages other than English?
Yes. The spoken language is detected automatically, so the captions and the transcript come out in whatever was said. The interface is available in English and Portuguese.
Can I finish the edit in Premiere or DaVinci?
Yes. Export a package with the cut timeline as .xml, .fcpxml and .edl, captions as .srt, the reframing already applied as scale and position on each clip, and a .cube with the colour. The desktop app adds the person matte.
Can I give it the script?
Yes — paste the script or open a .txt, .md or .docx. The selection then judges by delivery: which take says each line best. If the script does not match the footage, the app says so and falls back to judging each take on its own.
