About YingTu

YingTu is a browser studio for AI images and video. You write a prompt or upload reference images, pick a model and download the results; there is nothing to install.

• Image models: Nano Banana Pro, Nano Banana 2, Nano Banana 2 Lite, GPT Image 2 VIP, GPT Image 2.5 Flare / Sunburst and Seedream 5.0 Flash, from $0.018 to $0.09 per image, up to 4K.
• Layer decomposition with Seedream 5.0 Flash: one image becomes a filled background plus transparent PNG layers.
• Video studios for Seedance 2.0 / 2.5 and Wan 2.7.

Every generation is a call to the LaoZhang API. LaoZhang bills each image or video, and top-ups, balances and invoices are handled on laozhang.ai. YingTu does not sell credits or run subscriptions.

You generate with your own LaoZhang API key. The key is saved only in your browser and is sent only when you start a generation, either directly to LaoZhang or through a temporary YingTu forwarding route that does not store it.

New users can start without a key: the first 500 people who sign in with a Gmail account get $0.1 of credit for 30 days, for Seedream, Nano Banana and GPT Image models (not layer decomposition or video).

In short: your key and your images stay in your browser. The full details are in the privacy policy.

• In your browser: your API key (local storage), your generation history (IndexedDB) and your language preference (cookie).
• On our servers, only if you sign in with Google: your Google account ID, name, email and avatar, first and latest visit times, sign-in count, a country inferred from your IP (the IP itself is not kept), and when you claimed the free credit.
• Not stored: your API key, and prompts or images as a content library. There is no cloud history in the current version.
• Microsoft Clarity processes aggregated usage and diagnostics to help us find page problems.
