AI operates and records in a real browser
Enter a URL. Get an introduction video.
AI operates your website or web app in a real browser, records it, and turns it into an introduction video (MP4) with narration and music (subtitles if you ask for them).
New sign-ups are temporarily paused

Made with Eizeno
Each one was explored and recorded by Eizeno, then edited with a chosen taste or a custom request written in plain words. Hover to preview; click to watch the full video with sound.
Kumoita, Fudacho, Komado, Mitsumori, Shiftle and Toiawa, the subjects of these examples, are fictional services made by ZenLab Inc. to demonstrate introduction videos. They are not real products, and the shops, people and data shown are all fictional. Shots of desks and rooms are AI-filmed footage; the product screens are the real recordings.
Pick a taste, or describe it in your words
Once the recording is done, choose one of two ways to make the video. Either way, you can revise the result by chat as often as you like.
- TASTEChoose from 20 tastesMinimal keynote, TV shopping, late-night documentary, news, editorial and more: 20 tastes that differ down to how the screen is laid out. The AI recommends the 3 that suit your product. After choosing, you can add wishes such as "shorter" or "make it blue".
- CUSTOMCustom, in your own wordsJust write "no subtitles, music and bold animation" or "like a late-night documentary". The AI drafts a storyboard from styles it has learned from highly regarded product films, then builds the layout and motion for this one video from scratch. Where it suits the scene, it also films camera shots, such as a push-in onto a laptop on a desk that flows straight into the real screen.
In both cases, the product screen is the real recording, never redrawn, and is shown with a "Real product screen" label and the real domain.

Measured examples
| Exploring and recording a public web app in 17–25 steps | about 61,000–95,000 |
|---|---|
| One edit of the introduction video | about 40,000–105,000 |
| Adding an AI-generated opening shot | about 80,000 more |
In production tokens. Usage depends on the site, the number of steps and the video. If your balance runs out it stops there, and the recording so far is kept.
Frequently asked questions
Can I use a phone? Which browser do I need?
Creating videos with Eizeno requires Google Chrome on a computer and the Eizeno Browser extension. Production features are unavailable on phones and tablets. Open eizeno.com in Chrome on your computer.
Which sites can I use it with?
Public pages such as a home page or pricing page, and also screens that need a sign-in. Nothing to set up first: when the AI finds that a sign-in is needed during the exploration, you agree and then sign in yourself through a relayed screen; the AI never receives your password and only views after sign-in (please use a demo account with minimal permissions; see the manual). Please specify your own product, or one you are authorized to operate and record (see the Terms of Service). AI descriptions can contain mistakes, so please check the video before you publish it.
Could it buy or send something on the site?
The AI is controlled not to buy, pay, delete, post, send messages, create accounts or change settings, and not to leave the site. You sign in yourself; the AI never signs in. After sign-in, actions and requests that would change data are stopped before they happen. Depending on how a site is built, unexpected actions may still occur, and we can’t guarantee the result.
Can I stop it partway?
Yes. The stop button stops exploring or editing right away, and you only use tokens up to that point. If you stop exploring, the recording so far is kept.
Can I revise the finished video?
Yes. Tell it what to change in the chat and it edits the video again. Every version is kept so you can compare them. Each revision deducts the tokens used for that edit.
How many tokens does it use?
In our measurements, exploring a public web app in 17–25 steps used about 61,000–95,000 production tokens, and one edit of the introduction video used about 40,000–105,000 (about 80,000 more with an AI-generated opening shot). It varies with the site and the video.
How is the number of production tokens decided?
A top-up gives you the tokens that spend 50% of its pre-tax price on AI usage. Yen is converted to US dollars at a fixed rate of ¥180 per US$1, and US$1 of AI usage equals 162,162 production tokens (¥3,000 buys 1,351,350 production tokens). When you use Eizeno, the actual cost of the AI services (in US dollars) × 162,162 production tokens is deducted. The rate does not follow daily exchange rates.
How long are recordings and videos kept?
They are deleted 6 months after they are created. Please download the videos you need.
Can I pay in US dollars?
Customers outside Japan top up in US dollars (overseas pricing). $20 buys 1,621,620 production tokens (50% of the price goes to AI usage), and you can choose any whole-dollar amount from $20 to $5,000. No tax is added to US dollar payments. A billing address outside Japan and a card issued outside Japan are required; payments that don't meet these conditions are refunded automatically. Customers in Japan pay in yen, with consumption tax. Tokens are valid for 6 months from purchase, the same as with yen.
Can I get a refund?
As a rule, we don’t offer refunds for a change of mind. We handle duplicate or incorrect charges and refunds required by law. If something stops partway because of a problem on our side, we check and return the tokens to your balance. See the Commercial Disclosure for details.
