From rough recording
to polished demo
in 60 seconds.
Upload your screen recording. We rewrite the script, record a pro AI voiceover, and hand back a finished demo. No editing. No re-shoots.
Fix one line, not the whole video
Watch your polished video, click the line that sounds off, and re-voice only that line. Your video stays ready to download the whole time.
-
Watch it first. Your upload renders straight to a finished video. Lines that need a look are marked in orange.
-
Fix the line. Edit the words and hear the new voice before you commit.
-
Re-voice only what changed. Every other line stays exactly as it was.
- Nothing to lose
Your video stays downloadable until the new version is ready. If a fix fails, the video is unchanged and your edits are kept.
- New voice, same script
Change the voice or music for the whole video without losing your script.
- Your ending stays
The video runs to the end of your recording, not just the last spoken line.
Three steps. Zero complexity.
Record with whatever you already use. We handle the rest — in about the time it takes to refill your coffee.

Why I built DemoPolish.
I'm Cem. After years of shipping software, I've watched too many great products get judged by rough demos. The product is sharp — but the demo stumbles, the audio sounds amateur, and prospects bounce before the value lands.
Making a polished demo is brutal: stumbling over words, cursor wandering, editing eating your weekend. Most founders just ship what they have.
DemoPolish is the tool I wished I'd had. Upload your rough screen recording, get back a polished, narrated demo in about 60 seconds. No editing software. No studio. No apologies for the audio.
My mission is simple: every founder should be able to ship demos that look as polished as the product itself — regardless of budget or editing skill.
If you ever need a hand or want to share what you're building, email me directly at cem@demopolish.com. I read every message.
Thanks for being here.
