ONE CLICK, READY TO POST
The edit you were dreading is already done when the file opens.
A twenty minute take normally costs an evening: cutting the dead air, hunting the ums, writing captions, fixing the audio, adding the movement that keeps a static frame alive. Auto-Polish runs that whole pass on-device the moment a recording opens, so you start from a finished edit and adjust, instead of starting from a wall of raw footage and grinding.
Zella for Mac is out now on the Mac App Store, and Zella for iPhone is out now on the App Store. One Pro purchase covers both. See the mobile app →
WHAT CHANGES FOR YOU
- 01
An evening becomes a minute
Silence and filler cuts, extra cuts where you pause, keyword captions, noise removal, voice polish, emphasis zooms and a mood-matched music bed all land in one pass. What is left over is judgement, which is the part you are actually good at.
- 02
Nothing is decided behind your back
Silence and filler removal is reviewed before it applies. Auto-Polish never forces a colour grade onto your footage. Make it Viral works on top of the shape you already cut rather than replacing it, and every step is undoable fifty levels deep.
- 03
The retention craft, without studying it
A hook title with an opening punch-in, emphasis zooms on the lines that carry the point, and pattern interrupts through the middle - with matched sound effects under the strongest cuts when you reach for Make it Viral. These are the things that keep people watching, and they are applied for you.
ON BOTH PLATFORMS
What it does on each device.
On Mac
Auto-Polish runs the moment a recording opens on Mac, and is one tap on iPhone: silence and filler cuts, word-pop captions, zooms, a clean voice, blended joins and a music bed that ducks under your voice. Make it Viral runs that same pass and adds the two layers it holds back, a warm grade and matched sound effects under the strongest cuts. Auto-zoom follows the clicks your cursor genuinely made, because the Mac tracked them at capture, which is what produces the Screen Studio look without keyframing anything.
Download for Mac →On iPhone
Auto-Polish runs the same one-tap retention edit on the phone - silence and filler cuts, extra cuts where you naturally pause, a cross-dissolve on the widest-spaced joins, Beast keyword captions, noise removal and voice polish, a hook title, emphasis zooms and a ducked music bed. Make it Viral is here too, adding the colour pop and the matched sound effects on top. Clean Up, Make Vertical and Reel Pack are one tap each, and deleting a word in the transcript ripple-cuts the video.
Everything the mobile app does →Same project on both. Hand it from iPhone to the Mac as a .zella file and the clips, cuts, captions, titles, callouts and effects come with it. Mac and iPhone, side by side →
THE PROOF
The specifics behind the promise.
- Auto-Polish - silence and filler cuts, captions, zoom-ins, a clean voice, blended joins and ducked music, auto-run on every new Mac recording (it leaves your colour alone)
- Make it Viral - the whole ready-to-post pass in one tap: dead-air trim, punch-in zooms, transitions, SFX and a ducked music bed (keeps your original shape)
- Viral templates - Reel Pack, Hook Captions, Beat Drop, Cinematic Reel, Photo Cards, Reaction Split
- Auto-zoom that follows real cursor clicks - the Screen-Studio look
- Remove silences and filler words (um / uh / like), reviewed before you apply
- On-device auto-captions + neural noise removal - no upload, no transcript service
WHEN THIS MEETS A PAID CEILING
Auto-Polish and Make it Viral are free on every tier, on both platforms, and always will be. Pro matters only for what comes out the other side: a finished video longer than two minutes, or a 4K master.
Everything else is free forever: the complete editor, all the AI, unlimited recording, and watermark-free export up to 2 minutes at up to 1080p. 1080p is free permanently, and a free export is never stamped. Pro is $89 once and covers Mac and iPhone on a single purchase, and every new install runs the full Pro set for its first 7 days with no card and nothing to cancel. See pricing →

Who uses this, and for what.
Long-form that keeps people watching, cut in an afternoon.
Silence and filler removal tighten a rambling take automatically, emphasis zooms keep a static frame alive, and 4K export gives YouTube the master it wants.
