Live: this demo is making itself
Bring your prototype to life.
Turn your Lovable, v0, or hand-built prototype into a narrated demo video in minutes. Paste the link: AI writes the demo script and Democast films it. No screen recording, no retakes, no starting over when your prototype changes.
From prototype to living demo in minutes.
No recording session, no retakes. Democast remembers how to present your product: change the product or the story, render again, and the demo comes back in any voice, any style, any language.
From prototype to video in three steps.
1 — Point
Paste a link and one sentence: “Show off the billing flow.” Works with anything that runs in a browser: Lovable, v0, Bolt, or your own code.
2 — Watch
AI writes the demo script: the steps and the narration. Democast then drives your app with a human-like cursor and films a clean take while you watch. Read it over, fix a word or two.
3 — Share
A narrated 1080p video and a share page, ready for clients, investors, or your launch post. Want a change? Just say it: “punchier intro, skip the login.”
Ship a change, get a fresh video.
Democast remembers how to demo your product. When you ship, the video rebuilds itself: no re-recording, no stale screenshots in your pitch. And edits are surgical. Reword one narration sentence and only that sentence re-renders. Seconds, not minutes.
- →A current demo video with every release, automatically
- →The same demo in 30 languages, any voice
- →Your real product on screen, not slides or screenshots
- →For developers: the demo script is a plain file. Version it in git, render it in CI.

"step_id": 3,

"target": "#create",
"narration": "One click, and the invoice
is created, numbered, and scheduled.",
"wait_for": { "selector": "#invoice",

}One demo, every audience.
The words and the voice live in the script; the clicks don't change. So the same demo can be a sales pitch, a plain walkthrough, or a training video. Or all three in Spanish.
transcript
- Dawn, on the great open plains of enterprise software. Somewhere out there, a quarterly target moves. And here... Acme Billing stirs.
- The customer field. Empty. Patient. It has seen a thousand names, and forgotten every single one of them, exactly as the law requires.
- A name arrives. Globex Corporation. What did Globex buy? Nobody knows. Procurement approved it in March. That is all anyone will ever know.
- And then... the click. Witness it. The most dangerous predator in this ecosystem: a man with billing access.
- Invoice ten forty two. Twelve hundred and fifty dollars. Due in thirty days. It will be paid in ninety. The invoice knows this. It has made peace with it.
- This demo wrote itself, filmed itself, and narrated itself. No humans were harmed. One was mildly replaced. Democast. Show them what you built.
Not just prototypes.
If a browser can open it, Democast can film it. The same trick works for anything you'd otherwise present by hand:
Decks that present themselves
An HTML deck gets a voice and pacing. English for investors, Spanish for the team.
Sprint demos
Point it at staging on Friday. The what's-new video makes itself while the team is still in review.
Explainers and docs
Every how-to page gets a matching video from the same steps. It never goes stale.
Conference talks, minus the risk
The product segment of your talk, rendered flawless in advance. A live demo can fail on stage; a file can't.
Private beta
Show them what you built.
We're onboarding a handful of teams. Send one URL: a prototype, a deck, or a staging build. Get a narrated video back.
