01
Operates the real product
The agent clicks, types and scrolls through your live app in a cloud browser. No screenshots stitched together, no stock footage.
AI product demo video generator
The AI product demo video generator that uses your real app.
Paste your product's address and say what the demo should show. The AI opens your app in a cloud browser, clicks and types through the flow, writes and voices the script, and edits a 1080p MP4 with captions, auto zoom and music. Your first video is free.
Free: 1 video, no cardReady in minutes≈30 voice languages
B-ROLLWhat it does
One URL. The whole production.
Most AI video generators turn your landing page into an animated slideshow. This one operates the product itself, so the video shows what your customers will actually use.
02
Writes the script
It reads each screen and writes narration that opens with the benefit, not a list of buttons. You can change any line before the video is made.
03
Voices it in about 30 languages
Natural AI voiceover with matching captions. A version in another language reuses the same footage, so nothing is recorded twice.
04
Edits the cut
Auto zoom on every click, a smooth cursor, transitions, background music and sound effects, with the audio levelled for clear playback.
05
Gets past the login
Add a test account and the agent signs in off camera. If a code or CAPTCHA appears, it pauses and asks you on the page.
06
Gives you every format
From the same run: 9:16 and 1:1 clips, a product film, a clickable interactive demo and a step-by-step help doc.

SC 02How it works
Three takes. You only do the first.
You bring the link and the goal. The agent does the camera work, the voice and the edit, and checks with you before it spends a credit.
TAKE 1You
Paste the link, say what matters
Any URL. Behind a login? Add a test account; if a code is needed, the agent asks you on the page.
TAKE 2The agent
It scouts, scripts, you approve
The agent explores your product, finds the cleanest path and drafts the voiceover. Edit a line, then approve.
TAKE 3The cut
Get the final cut in minutes
Every click lands on the word that describes it. Zoom, captions, music, sound effects and your brand are in.
NOTESWhat works
What makes a product demo video work.
The agent follows these rules by default, so the first cut is already close to what you'd publish.
RULE 1
Lead with the outcome
The first few seconds say what the customer gets, before any button is clicked.
RULE 2
Show one flow, start to finish
One job done end to end beats a tour of every menu. Viewers remember a story, not a feature list.
RULE 3
Keep it short
60 to 90 seconds for a landing page, under a minute for social. Tutorials can run longer.
RULE 4
Zoom where the action is
Every click is framed close enough to read, even on a phone.
RULE 5
Captions on
Many people watch with the sound off, so every line of narration is also on screen.
RULE 6
End with one next step
One clear call to action, like a free trial or a booked call, not three.
SC 03One take, every format
Shoot once. Ship everywhere.
The same run becomes your landing-page video, social clips, a launch film, a clickable tour and a help doc.

SC 05Why not a screen recorder?
The only one that runs your product.
Recorders still need you on camera. Avatar tools don’t show your real UI. Tour builders don’t make video. Compared by category, not by brand.

SC 07FAQ
AI product demo video questions.
Is the AI demo video generator free?
Your first video is free: up to 60 seconds, 1080p, with a small watermark, and no card needed. Paid plans start at $39 a month and remove the watermark, including from the video you already made.
How long does it take to generate a demo video?
Usually a few minutes. The agent explores your app and writes a storyboard first; once you approve it, the video renders. Longer videos take a little longer, and we email you when it's ready.
How long should a product demo video be?
For a landing page, 60 to 90 seconds. Sales follow-ups and launch clips work at 45 to 60 seconds; onboarding and tutorials can run 90 seconds to a few minutes. You choose the length: up to 60 seconds on the free plan and 5 minutes on paid plans.
Can I edit the script before the video is made?
Yes. The maker shows a storyboard first, with every scene and its narration. Change the words, title, voice, music or length, then make the video. Changing the music later is free; rewriting the voiceover costs half the video's credits.
Which websites and apps does it work with?
Any website or web app a browser can open on the public internet, including pages behind a login. It can't reach sites that only run on your computer (localhost) or inside a private network, and it doesn't record desktop or native mobile apps.
What if my app has a CAPTCHA or two-factor login?
The agent pauses and asks you on the demo page. Type the code, or take over a live view of the page to solve the CAPTCHA, and it carries on. If you've left the page, we email you.
Can I make the same demo in other languages?
Yes, in about 30 languages including Spanish, German, French, Japanese and Chinese. A new language version reuses the same footage, so nothing is recorded again.
Can I embed the demo on my website?
Yes. Create a share link or an embed code from the video page; the interactive demo can be embedded too. You can turn sharing off at any time.
Who owns the videos I make?
You do, and you can use them commercially. The music and sound effects we supply are licensed for use in those videos.
Can I upload a screen recording I already have?
No. Demo Tool AI records the product itself, so every click, zoom and caption lines up with the narration. If you already have footage you like, a video editor is the better tool.
Is there an API?
Not yet. Today you make videos on the website. If you need an API, email support@demotoolai.com and tell us what you'd build.
