HUUUIAI guide: online canvas, material groups and desktop creation

Start with one clearly defined task

For a first HUUUIAI task, complete one image online: sign in to the workspace, import a reference, confirm Composer inputs and parameters, then generate, preview and download. If you need client-only batch capabilities, check the desktop version on the download page.

HUUUIAI is an AI visual creation product from Shenzhen Zhihui Engine Technology Co., Ltd. It organizes materials, generation and editing around a canvas. Historical Photoshop plugins, the toolbox, desktop applications and the online experience are related product forms, but their capabilities are not interchangeable. An article about a model does not establish access for your current account.

Check assets and task limits before importing

• Prepare authorized assets with a clear subject, and define purpose, aspect ratio and the details to preserve. To generate without references, choose a model that supports text-only input.
• Image imports must stay within 20,250,000 total pixels and an 8192px longest edge. If either limit is exceeded, choose to resize for upload or cancel, and retain the local original.
• Accepted image, video and audio types and counts depend on the current model and workflow. Check this task's inputs after upload; seeing an asset on the canvas is not enough.

Complete a first creation

Canvas filters control what is displayed; Composer mode determines the generation task. Switching the canvas to Videos does not turn image references into video inputs or replace cleaning up the input bar.

1. Sign in to the online workspace and import a clear reference, or prepare a brief for a model that supports text-only generation.
2. Choose image, video or audio generation at the top left of Composer, then check the available models.
3. Select references from the canvas, inspect the input items and their order, and remove unwanted assets individually.
4. Set the aspect ratio and other output options supported by the model. Check pricing and submission requirements before generating.
5. Open the completed result, inspect subject, text and structure, download the actual file, then decide whether a local edit is needed.

Groups, Composer inputs and parameter picking differ

Groups organize assets. After selecting a group, or box-selecting it with other objects, inspect the individual members listed in Composer. Remove unwanted inputs one at a time without dissolving the group or deleting source assets. Check group order and input roles separately; members hidden by a display filter have not been deleted.

Starting canvas picking from an extension workflow parameter fills only that parameter, without replacing the entire Composer input set or changing group membership. Back in the form, check the main-image and reference slots. Cancelling preserves the previous value.

Choose the correct reference method for video

First/last-frame mode uses dedicated image slots for opening and ending frames. Smart-reference mode accepts images, video or audio according to model support. Adding two images to smart references does not set a first and last frame.

Models do not all share the same reference types, durations, resolutions or audio capabilities. Recheck inputs and settings after changing mode or model. A prompt cannot enable an unsupported capability.

Start troubleshooting with these checks

• An asset is on the canvas but did not affect generation: check the Composer input bar or the actual parameter slot in the extension workflow.
• Submission stops working after switching models: check required inputs, asset count, media types and parameter compatibility.
• A preview is soft or will not open: check resource loading and task status, then download the file for inspection instead of immediately generating again.
• An extension workflow's batch button shows a download notice: this is a client-only batch entry point. The online application does not execute that batch task.

Save the files, then decide whether to use desktop

Local media used for generation is uploaded, and generated results return as remote media URLs. Local browser history is not permanent storage: it currently defaults to seven days of retention, up to 80 displayed entries and up to 120 stored entries per user. Clearing site data can remove records, so save inputs and final files separately.

The download page offers Windows and macOS options; Mac users should distinguish Apple Silicon from Intel. Confirm that the current client version supports the needed features before installing. Do not assume automatic browser-canvas migration, identical models across applications or offline generation just because the app is installed.
