Your music video, cut to the beat, with software you own.

MadSync runs on your PC, costs $49 once, and the free demo is the whole app. There's no account to create, and nothing you edit ever leaves your machine.

Signed with my legal name

Windows shows Michael Raposa as the verified publisher before anything runs.

Everything stays on your PC

Editing, AI, and export all run locally. MadSync keeps working offline, and the demo needs no internet at all.

Pay once and it's yours

One payment, no renewal, and your license doesn't expire.

Watch it snap cuts to the beat.

This video was edited and exported in MadSync.

Try the whole editor before you spend anything.

The demo is the full MadSync, not a stripped trial, and it doesn't expire. Detect the beat, split a song into vocals, drums, bass, and instruments, sync lyrics word by word, add visualizers and effects, and export finished video. Your projects are real work, and they're yours to keep.

  • Beat detection that maps drum hits, downbeats, and the full beat grid

  • Stem separation that runs on your machine, not a server

  • Auto lyrics with word-level timing, in full-sentence or one-word karaoke

  • Audio visualizers that pulse on your actual beat grid

  • Lo-fi atmosphere overlays like rain, snow, dust, and embers

  • Text styling, image overlays, transitions, and beat-triggered effects

  • Export MP4, WebM, or GIF up to 1080p for YouTube, TikTok, and Reels

When you're ready, $49 removes the watermark and the 60-second export cap. You enter your key inside the app and keep working. There's no second download and no reinstall. You already know exactly what you're buying, because you already used it.

And if you refund within 14 days, the app returns to demo mode. Your projects stay on your machine either way.

Many video editors charge you every month. MadSync charges you once. Stop paying for a rented tool and it stops working. This one keeps going.

Built by one person you can name.

I'm Mike. I build Windows tools from Southcoast, Massachusetts, and the same person who writes the code answers the support email, usually within a business day. When you buy a Madfable tool, that's who you're dealing with.

There's no support team and no ticket queue. If something breaks, you're emailing the developer who can actually fix it.

The questions you should ask a one-person software company.

Your price is fixed the day you buy, updates are included, and your license never expires.

Don't take my word for any of this.

Trust should come from things you can check, so here's how to check them.

  1. Check the signature. Right-click any Madfable installer, choose Properties, then Digital Signatures. You'll see my verified name on the certificate.

  2. Cut the internet. Run MadSync offline and everything still works, because your files are processed on your machine. The demo never needs a connection at all, and a paid key only needs the internet once, to activate.

  3. Read the license. The EULA ships in plain language with the installer, including the demo terms and what happens on a refund.

  4. Check who charges your card. Payments run through Lemon Squeezy, a merchant of record owned by Stripe. Your payment details go to them, not to me.

  5. Run the demo. It's the strongest proof on this page: the full app on your machine before you spend a dollar. Download it and see.

How buying works.

1. Buy it

One payment through Lemon Squeezy, the merchant of record. They handle the card, the receipt, and the tax paperwork.

2. Install it

Download the signed installer and run it. You'll see my name on the publisher line. Setup takes a couple of minutes.

3. Keep it

The software runs locally and keeps working whether or not I ship another update. When I do, it's included.

If you'd rather own your tools than rent them, you're who I build for.

Start with the free demo. It's the whole editor, and it doesn't expire, so take your time.
