Demo Editor

About

An AI Director reads your landing page, captures your real pages, and writes a storyboard, which you can correct in Director's notes before any frame is made. You can also add a rough screen recording so the video shows the app behind your login, with the Director cutting out typos and stumbles. Every cut is checked for cut-off text, low contrast, clipping, and overlong runtime, and it is laid out separately for 16:9, 1:1, and 9:16 feeds rather than cropped.

FAQ

How do I make a product demo video?

Paste your landing page URL and pick a teaser, hook, pitch or demo. For a demo of the app itself, also record yourself doing one real task in your product, start to finish. The Director cuts it into a finished video with voice-over and music. You check the storyboard first and ask for changes in plain words.

How long should a demo video be?

As short as the job allows. A teaser works in 15 to 30 seconds, a hook in 20 to 40, a pitch in 30 to 45, a demo in about a minute. Most people stop watching a launch demo after a minute, so every cut stays inside those limits.

What's the difference between a teaser, a hook, a pitch, and a demo?

A teaser makes people curious and holds back how it works. A hook stops the scroll with one idea and one call to action. A pitch persuades: problem, product, proof, offer. A demo, sometimes called an explainer, shows the product doing one real task, start to finish: how it works, not why to buy it.

Why not make it myself with Claude and Remotion?

You can. Most founders who try spend a weekend prompting and fixing frames by hand, and end up with the default AI look. The Director works from your real footage and your brand, writes a storyboard you can correct, checks every frame and takes changes in a sentence.

Do I need to know video editing?

No. There's no timeline to learn. Upload, read the storyboard, and tell the Director what to change, the way you'd brief a person.

Do I need a screen recording?

No. Your URL is enough for a teaser or hook: the Director captures your real pages, copy and brand. A screen recording is how the video shows the app behind your login, so add one for a pitch or demo. One rough take is fine.

Can it use my real product, not stock footage?

That's the point. It reads your site, uses your screenshots and cuts your screen recordings, including screens behind your login. It never invents features or results your product doesn't have.

Which formats and languages do I get?

Make it portrait 9:16, square 1:1 or landscape 16:9, then tick where you'll post it: TikTok, Reels, Shorts, X, LinkedIn, Threads, Reddit or your site. Each one gets its own file of the same video, laid out again for its frame when a crop would cut too much, with the text kept clear of the app's buttons and caption. You can watch it under the TikTok and Reels screen before you post. Voice-over in over 80 languages, from English, Spanish and Japanese to Hindi, Arabic and Bahasa Indonesia.
