Set Up DocCenter

On This Page

The capabilities described on this page are included in Appian's advanced and premium capability tiers. Usage limits may apply.

Administrators should ensure their Appian environments meet the following requirements before using DocCenter.

DocCenter environment requirements

To use DocCenter, your Appian environment must have the required plug-ins and AI skills enabled. When you deploy models to other environments, each target environment must also have these plug-ins and AI skills enabled.

Note: Earlier versions of DocCenter required you to set up API keys to deploy models to higher environments. API key setup is no longer required as of DocCenter 3.0.

Model and region selection

DocCenter is powered by AI models available in Appian. Administrators can control model configurations on the AI Services page in the Administration Console.

Tip: Before installing or upgrading DocCenter, Appian recommends administrators enable a currently supported model and select an inference profile on the AI Services page.

When configuring extraction or classification models, DocCenter displays all preconfigured provider and model combinations available in your environment. The provider list includes Appian's default AI provider as well as any custom providers configured through the Administration Console. You can assign different providers to individual extraction models, classification models, and AI Reviewers, allowing you to mix and match infrastructure across your DocCenter models.

Note: Providers must be preconfigured in your Appian environment settings before they appear in DocCenter. You cannot create or configure providers from within DocCenter. For information on setting up custom providers, see AI Services.

DocCenter can extract and process data from multiple data inputs, such as visual and text-based content. You can use visual extraction by selecting Visual as you define fields in your extraction model.

Enabling visual extraction may require you to enable cross-region inference profiles to send model data to another region where multimodal models are supported. If you are using an older model that does not use inference profiles, contact Appian Support to use DocCenter by sending your data to a supported region.

Required plug-ins for DocCenter

The following plug-ins are required in the target environment:

Note: For optimal performance and security, always use the latest available version of all required plug-ins.
