AIDemo.Video

AIDemo.Video turns a website into a narrated product demo video from nothing more than its URL. You paste the address of a SaaS product, an app page or a marketing site, optionally tell it what to focus on, and it comes back a few minutes later with a finished 1080p MP4 that has a script, a voiceover, timed captions, sound effects and scenes cut from the real pages. There's no screen recording session and no editing timeline to learn. It's aimed squarely at the demo, explainer, launch and onboarding videos that every software product needs and few teams get around to making.

The problem it solves is that demo videos are expensive in time even when they're cheap in money. Somebody has to write the script, record the screen without mistakes, record or generate the narration, sync the two, and cut captions, and the whole thing goes stale the next time the product ships a redesign. For small teams that means the demo never gets made or never gets updated. Even teams with a designer tend to put the demo video at the bottom of the list because it's a day of work for a two-minute asset. AIDemo.Video compresses that into a form you fill in and a few minutes of waiting.

The pipeline works like this. An AI browser loads your site and identifies the key screens, a script is written around what it found and any direction you gave, narration is generated in the language you choose, and scenes, captions and sound effects are assembled around it. When it's done you can download the finished MP4 or the individual parts, which means a clean video track without narration, the voiceover as a WAV file, the sound effects track, and captions as SRT or VTT, so a video editor can rework it if you want to. Scenes are built from the actual pages rather than stock footage, so the video shows the product as it looks today, and the research step means the script reflects what the site says about the product rather than a generic template.

Editing after the fact is built in rather than a restart. You can revise the script, regenerate a single scene, or talk to the AI editor in plain language and let it make the change. Audio is re-synced automatically after edits, so nudging a sentence doesn't leave the narration drifting out of step. When the product changes, you regenerate rather than starting from scratch. The one hard requirement is that pages have to be publicly reachable. For a product behind a login, the guidance is to point it at a demo environment or the marketing site instead. A short description of what to emphasise, such as a particular feature or audience, steers both the screens it picks and the script it writes.

It's for SaaS companies, product teams, indie app developers and marketers who need demo, explainer, launch and onboarding videos and don't have a video person. It also suits agencies and freelancers producing a lot of short product videos for clients, where the per-video cost matters more than fine creative control. Founders launching on a directory or a marketplace listing, where a short video lifts a page, are an obvious fit, as are teams that need the same demo in more than one language for different markets.

What sets it apart is the way credits work. Credits are usage-based rather than a flat per-video charge. The system reserves a safe maximum before generation, measures what the AI, voice, imagery, research and rendering actually used, and returns the rest automatically. A typical video lands between roughly 25 and 120 credits, with a short focused clip nearer the bottom and a long narrated piece well above it. Failed generations aren't charged, monthly credits roll over for one extra month, and the videos you make are yours to use in ads, on your site and on social. The FAQ is specific about credit rules, rollover and what happens when a job fails, which is more than most credit-based tools spell out.

Access is paid, and free creation is currently paused during high usage. The cheapest way in is a one-time First Video Pass at $1.90 for 20 credits, followed by a $4 Starter Plus Pass with 50 credits, both valid for 30 days. Subscriptions are Creator at $14 a month for 300 credits, Pro at $29 a month for 1,000 credits, and Studio at $59 a month for 2,200 credits. Support runs through a contact form, and the site promises to make it right when something fails on their side. No watermark or resolution limit is mentioned on the pricing page, and the one-time passes are the sensible way to test whether the automatic script and pacing suit your product before committing to a subscription.
