Most short-form video is one person talking to a camera. Making that watchable on a muted feed means captions; making it feel edited means cutaways; making it reach people means captions in the language they read. Each of those is tedious in a timeline editor, and together they are the reason so many good clips never get posted.
KatKut AI does that work automatically and then gets out of the way. Studio Editor transcribes your speech, writes word-timed captions in the language you spoke or translates them into another, cuts in matching stock footage, and opens the result in an editor where you can change anything before it is rendered. It stops short of being a full editor on purpose: music, voiceover and everything else you already do in CapCut, TikTok or Instagram stays there.
Two tools in one app
Studio Editor
For one talking-head video. Automatic captions in 101 languages, translation, native or Roman script, AI-picked B-roll, automatic motion graphics, sound effects and transitions, an opening hook, trending caption styles, and a timeline editor for manual changes. Export renders on your phone, vertical 9:16 or widescreen 16:9.
Explore Studio EditorMulti-Clip Reel
For many short clips shot across a day. KatKut AI scores each clip for sharpness, exposure, frozen frames and sound, keeps the best moments, and sequences a 9:16 reel in one of five styles. Entirely on-device.
Reel questionsWhat we believe
Say exactly what leaves the phone
Studio sends the audio track for transcription and the text for planning; the video file never leaves your device. Multi-Clip Reel sends nothing at all. We write that down rather than round it off.
The AI proposes, you decide
Every caption and every cutaway is editable, and nothing is encoded until you tap Export. A good automatic result should save you time, not take away control.
No language is the unusual one
English sits in the same list as Japanese, Turkish, Hindi and Arabic: 101 spoken languages and 140 caption languages, with no "supported languages" tier and no language treated as the default.
Fits the way you already work
KatKut AI gets you to a captioned, edited video fast and hands it straight to the app you finish in, such as CapCut, TikTok or Instagram.
Who builds it
KatKut AI is built and maintained by Sanjaya Bhattarai, an independent developer based in Helsinki, Finland. It began as a tool that turns a day of short clips into a reel, and grew Studio Editor around one conviction: captions should work as well in any language as they do in English, from Nepali and Hindi to Japanese and Turkish. Questions and feedback go straight to the person who wrote the code: khelset.com@gmail.com.
More questions
Questions specifically about captions, translation, B-roll and editing are answered in the Studio Editor FAQ. The general, reel and billing questions are here.
General
What is KatKut AI?
KatKut AI is an AI video editing app for iPhone and Android with two tools. Studio Editor takes one talking-head video and adds word-timed captions in any of 101 languages, optional translation into 140, AI-picked B-roll, motion graphics and an opening hook, with a timeline editor for manual changes, and exports it 9:16 for TikTok, Reels and Shorts or 16:9 for YouTube. Multi-Clip Reel takes many short clips and automatically selects, trims and sequences the best moments into a 9:16 vertical reel. Both export on your phone and save to your gallery.
Which tool should I use: Studio Editor or Multi-Clip Reel?
Use Studio Editor when you have one video of yourself speaking and want captions, translation or B-roll. Use Multi-Clip Reel when you have many short clips from a day, a trip or a shoot and want them cut into one reel. Both tools appear on the home screen and share the same drafts and exports list.
Do I need an account?
Not for Multi-Clip Reel, which works without signing in. Studio Editor and paid plans use a free account. Sign-in is with Apple or Google, depending on your device.
Does KatKut AI work with CapCut?
Yes. KatKut AI does the time-consuming part, a captioned, edited video (Studio) or a reel cut from your best moments (Multi-Clip Reel), and hands it straight to the app you finish in. Share it from the export screen to CapCut, TikTok or Instagram to add music, a voiceover or extra effects.
Multi-Clip Reel
How does Multi-Clip Reel decide which moments to keep?
It measures every clip on your phone for sharpness, exposure, motion and frozen frames, and audio energy, then keeps the sharpest, best-lit, steadiest segment from each and skips blurry, dark or shaky footage. The style you choose (Auto, Travel & Adventure, Mini Vlog, Food & Cooking, or Unboxing & Style) shapes how those moments are cut together. You can trim, reorder, mute or remove clips afterwards.
What if some of my clips are landscape or square?
They are shown in full: the original footage is centred and the space around it is filled with a blurred, enlarged copy of the same clip, so the output is always a clean 9:16 vertical video.
How many clips do I need, and how long can the reel be?
Four or more clips works best; many people use 20 to 40 short clips from a day. You choose a target length from under 30 seconds to over two minutes, and the tool fits the best material to it.
What happens to the original audio in a reel?
By default, Smart audio decides per clip: it keeps sound where it is part of the moment, such as talking, music or cheering, and mutes the rest. You can instead mute every clip up front for a voiceover, or keep every clip's sound. Each clip's mute can be changed in the editor.
Does Multi-Clip Reel upload my clips anywhere?
No. Analysis, selection, editing and export all run on your phone. No part of your footage is sent to a server. Studio Editor is different: it sends the audio track for transcription, which is explained on the Studio Editor FAQ and in the privacy policy.
Accounts and billing
How do I subscribe to a paid plan?
Open Settings in the app and tap See plans. On iPhone, plans are Apple in-app purchases billed to your Apple ID. On Android, the app opens a secure Stripe checkout that links the subscription to your KatKut account. Pro is $3.99, Pro Plus $6.99 and Pro Max $9.99 per month in the US; the App Store shows the local price for your country. Your plan activates as soon as payment completes.
How do I cancel my plan?
On iPhone, cancel in Settings › Apple Account › Subscriptions, as with any App Store subscription. On Android, open Settings in the app and tap Manage or Cancel Subscription, which opens your subscription management page. Cancelling stops future renewals; your plan stays active until the end of the paid period, then you are back on Free.
How do I delete my account?
Open Settings in the app and choose Delete Account. This removes your account information, including your Studio usage count. If you subscribed on iPhone, also cancel the subscription in Apple's Subscriptions settings; deleting the account does not cancel an Apple subscription. You can also email us to request deletion.
What phones does KatKut AI support?
iPhone running iOS 16.4 or later, from the App Store, and Android phones from Google Play. Export uses your phone's hardware video encoder, so it works on mid-range devices, not only flagships.
