Stop editing UGC ads one at a time.
Mashcut is an AI video editor for UGC ads. Pick a hook for each ad and your demo from your camera roll, and it cuts up to 5 ready-to-post 9:16 ads, each opening with a different hook, so you know which one won.
Four taps from the shoot to five ads.
Mashcut treats an ad as what it is: a hook, then a demo. You pick the parts. It does the assembly.
- Step 01
Pick your hooks
The opening moment. Your face and a bold claim said to camera, or a reaction or reveal with no words. Pick up to 5 takes straight from your camera roll.
- Step 02
Pick your demos
The product moment. A screen recording, an unboxing, a walkthrough. Mashcut uses the best parts after each hook.
- Step 03
Tap Generate
Mashcut cuts one ad for each hook, removes the ums and pauses and adds captions from your words. Five hooks make five ads.
- Step 04
Post and learn
Each ad opens with a different hook, so when one takes off in your ad account, you know which opener did it and what to shoot more of.
Read the full guide: How to test 5 hooks from one shoot
Everything between the shoot and the ad account.
Not another editor. Mashcut is the step after you film: it cuts, captions and sizes your ads, and you run it from your phone.
Straight from your camera roll
Tap the hooks, tap the demos, done. No transfer to a laptop, no import, no timeline.
Cuts between words
Every cut lands between words: one take of each repeated line, no ums or pauses, and the sound fades across each cut so the join disappears.
Safe for every feed
Every export is 9:16 at 1080×1920 and safe-zoned for TikTok, Reels and Shorts UI. No black bars, no caption under the like button.
One ad per hook
Each ad opens with a different hook and uses the best of your demo, so when one wins, you know which opener did it.
Up to 5 ads from one shoot
Add a hook and you get another ad, without another edit.
Pick the winners from your phone.
Watch every ad, fix any caption and export the ones you'll post. Tap a tile to try it.
Swipe through every ad
Watch each ad full screen and swipe to the next, each labelled by its hook.
Fix the words
Change any caption, or rewrite or remove the title. Within limits, correct the cut too: use another take of a part, or trim, split or remove a clip.
Export and share
Each ad is one 9:16 file. Exporting it doesn't use a credit, even again after an edit. Then share it anywhere your iPhone can.
Editing was built for one ad. Testing hooks needs five.
The opening line decides whether anyone keeps watching. To find the one that works, you test several. That's where editing one ad at a time falls apart.
| To test 5 hooks | Editing by hand | Mashcut |
|---|---|---|
| Repeated lines and retakes | Scrub every take and pick one | Keeps one take of each line |
| Ums and dead air | Trim them clip by clip | Cut for you |
| Captions | Type them, or fix auto-captions, file by file | Burned in from your own words |
| One more hook | Rebuild the edit | One more ad, up to 5 per set |
| Safe zones | Checked by eye, file by file | Captions placed clear of the feed's buttons |
| Where you work | A laptop and a timeline | Your iPhone. No timeline. |
For people who test hooks, not just post them.

Questions, answered.
Is Mashcut an iPhone app?
Yes. Mashcut is an iPhone app, on the App Store. You film or pick your clips on your phone; Mashcut uploads them and does the editing on its servers.
What do I need to film?
A hook for each ad: the opening line said to camera, or a reaction with no words. A demo that shows your product while you explain it, in up to 10 clips. And, if you like, a call to action to close. A call to action needs speech; a hook can be a silent reaction or reveal, and a silent screen recording works as a demo. Clips can run from 1 second to 3 minutes, with up to 10 minutes of footage per set.
How many ads do I get?
You choose, from 1 to 5 per set. Each ad opens with a different hook, followed by parts of your demo and your call to action.
Does Mashcut add music, voices or AI footage?
No. Mashcut edits, and never puts words in your mouth. It keeps one take of each line you repeat, cuts the ums and pauses, and burns in captions made from your own words. In Auto Edit, an ad's hook can be a short line written from something you said, using words from your take, a few plain framing words and your numbers as you said them, and you can change it before you export. It adds no music, voices or stock footage.
Can I change an ad after it's made?
You can fix the words: change any caption, or rewrite or remove the title. You can also correct the cut, within limits: use another take of a part, or trim, split or remove a clip.
What do the finished ads look like?
9:16 MP4s at 1080×1920, up to 35 seconds long, with captions placed clear of the feed's buttons. Share each one from the app anywhere your iPhone can.
Who owns my footage?
You do. Mashcut doesn't claim your clips, and it doesn't use your footage, audio or words to train AI models.
How much does it cost?
New subscribers start with a 3-day free trial. After that, Creator includes 100 credits a month and Pro 300, billed monthly or yearly. Making an ad uses 1 credit; exporting is free. Prices are shown in the app before you buy.
What about Android?
Mashcut is iPhone only for now.
Your next hook test starts with one shoot.
Film your hooks, add your demo and get up to 5 ads back. Try it free for 3 days.
