Eizeno

Terms of Service

Established: October 29, 2026. Last revised and effective: November 3, 2026. If this English translation differs from the Japanese original, the Japanese version prevails.

These terms set out the conditions for using Eizeno (the "Service") provided by ZenLab Inc. ("we"). By signing in to the Service, you agree to these terms and to the Privacy Policy.

1. The Service

The Service has AI (Anthropic's Claude) operate the website or web service at the URL you specify (the "Target Site") in a dedicated tab that the Chrome extension opens in your Chrome browser, find its main features, buttons and user flows, and record the session. Following the taste and requests you choose, AI then edits the recording into an introduction video with narration, music and an AI-generated opening shot (subtitles on request). You can revise the video by chatting, and each version is kept. For each version of the video we also make a thumbnail image that contains text and the icon from the Target Site. We deliver the recording, the list of features found, a summary, the introduction videos and the thumbnails (the "Deliverables"). Narration, music, opening shots and thumbnails are generated with Google's Gemini API.

2. Account

You sign in with a link we email to you or with your Google account; either way, your account is identified by your verified email address. Only you may use your account, and you may not transfer or lend it to others.

3. Target Sites and your responsibilities

Only specify services you provide yourself or that you are legitimately authorized to operate and record. The following are prohibited:

The dedicated Chrome tab may open, operate and record pages linked from the Target Site when needed for your video. This includes links to other sites and links that would normally open a new tab. Use pages you are authorized to operate and record, including linked pages. To explain a relevant example or demo in your video, our servers may read text from a public external page linked directly from the Target Site. They do so without using your sign-in information. We control the AI so that it does not purchase, pay, delete, post, send messages, create accounts, sign in or change settings. Depending on how a Target Site is built, unexpected actions may still occur, and we do not guarantee the results. You are responsible for the Target Sites you specify and for the results on those sites of your use of the Service.

Personal information shown in the dedicated tab, such as names, contact details or images, may appear in recordings and finished videos and may be sent to us and to Anthropic to produce your video. Recording does not stop solely because personal information may be visible. We do not guarantee that such information will be kept out of recordings or that masking or editing will detect or remove it all. Use only data you are authorized to record and transmit, and review the video before sharing or publishing it.

Target Sites that require signing in

When you have the Service explore a Target Site that requires signing in, you sign in yourself in the dedicated tab of your own Chrome browser used for the exploration (the Chrome extension). While you sign in, the AI's actions and the recording are paused. The AI never enters sign-in details and never signs in again. By using this feature you agree to the following:

We do not receive the sign-in details you enter in the dedicated tab (such as passwords and one-time codes). The screens and input during sign-in are not given to the AI or recorded. The AI's actions and the recording resume only after you explicitly resume the exploration and the protections are confirmed. After sign-in, the AI only views, and we stop actions and requests that would change data before they happen to the extent we can detect them, but depending on how a Target Site is built we cannot guarantee this. The signed-in state remains in your Chrome browser and is not discarded by us; sign out on the Target Site if needed. We may stop the exploration on Target Sites where the protections cannot be confirmed.

4. Rights in and use of Deliverables

Recordings include screens of the Target Site. Rights in works, trademarks and other content on the Target Site belong to their respective owners. For the parts of the Deliverables in which we hold rights, we grant you a free, non-exclusive, perpetual license to copy, edit, publish and distribute them. We grant no license and give no warranty regarding third-party rights contained in the Target Site. The AI's descriptions, summaries, narration and subtitles may contain errors, and AI-generated music and footage may happen to resemble existing works; we do not warrant that they do not infringe third-party rights. Please check the content yourself before publishing or using it. We use Deliverables only to provide the Service and investigate problems.

By sending a URL in the Service's chat or input field, you are deemed to agree that we use the information on the Target Site at that URL (text, images, icons, logos, screens, videos and the like) to make the Deliverables, including introduction videos and thumbnails. Thumbnails may contain text from the Target Site's pages (titles, headings, descriptions) and its icon or logo. Specify a Target Site only after confirming that you have the right to use these in the Deliverables.

5. Fees and top-ups

To use the Service, you prepay for production tokens (a "top-up"). Prices and sales terms are set out in the Commercial Disclosure.

6. Retention

Recordings, screenshots, introduction videos and their assets, and exploration and editing records are deleted 6 months after they are created. Please download and keep any recordings and videos you need. Retention periods for account, balance and purchase records are set out in the Privacy Policy.

7. Changes to and suspension of the Service

We may suspend or change all or part of the Service for maintenance, failures, outages of external services and similar reasons. If we end the Service for our own reasons, we will handle unused balances in accordance with applicable law.

8. Limitation of liability

We are liable for damage you suffer through the Service only where we are at fault. Liability is limited to ordinary, direct damage, up to the total amount you paid us as fees for the Service (the price of production-token top-ups, including tax) during the 6 months before the event that directly caused the damage. If you paid nothing during that period (including where you used only the free tier or tokens granted by us), the limit is ¥1,000. It excludes lost profits, loss of data and damage arising from special circumstances. This limitation does not apply in cases of our intent or gross negligence, or where the law does not permit it.

9. Changes to these terms

We may change these terms where the change is in the general interest of users, or is reasonable in light of its purpose and necessity, the appropriateness of the new content and other circumstances. We will announce the new content and its effective date before it takes effect, on the Service or by email to your registered address. Changes that disadvantage users, such as price increases, will be announced at least 14 days before they take effect.

10. Governing law and jurisdiction

These terms and the Service are governed by the laws of Japan. The Tokyo District Court has exclusive jurisdiction as the court of first instance for any dispute concerning the Service.
