documentation for the dotCMS Content Management System

dotAI integrates powerful AI tools into your dotCMS instance, allowing new horizons of automation — content and image generation, semantic searches, workflows capable of handling nitty-gritty procedures like content tagging, and more.

dotAI Tool under Dev Tools toolgroup.

Currently, these integrations leverage the services of OpenAI. In future iterations, the choice of AI service provider will become a configurable option. Additionally, the dotAI features will soon be available by default; at this moment, it requires one of two activation methods:


This feature requires the following:

  1. dotCMS Enterprise Edition, as this plugin has both Workflow and App components, both of which are Enterprise only;
  2. An OpenAI API key, obtained separately;
  3. Postgres 15 with the pgvector extension installed.
    • If you're on dotCMS Cloud, we'll handle it!
    • For self-hosted customers, see below.


For embeddings to function, a vector extension must be added to the Postgres database. The dotAI plugin will add this extension automatically, but this process requires dotCMS's database user has superuser privileges, ensuring extensions can be installed.

If the database user does not have sufficient rights, it may be necessary for IT or administrators to manually add the extension. The simplest implementation is via the ankane/pgvector Docker tag, easily accessible via the command docker pull ankane/pgvector. The image can be applied to a docker-compose.yml by adding it to the database section:

    image: ankane/pgvector

Note also that these privileges are only required for the extension's installation, and not for its subsequent use.

App Configuration

A full list of the App integration fields follows:

API KeyYour account's API key; must be present to utilize OpenAI services.
Role PromptA prompt describing the role (if any) the text generator will play for the dotCMS user.
Text PromptA prompt describing the overall writing style of generated text.
Image PromptA specification of output aspect ratio. If the ratio specified differs significantly from the Image Size (below), the image will “letterbox” accordingly.
Image SizeSelects the default dimensions of generated images.
ModelThe text model used to generate written responses.
Image ModelThe image model used to generate graphical responses.
Auto Index Content ConfigAllows App-level configuration of content indexes used as the basis for text generation. Takes a JSON mapping; each property name becomes an index, and each value is the Content Type it will take as its target content. Optional; indexes are also fully configurable under the dotAI Tool. Most useful when configured in the System Host, as this will instantiate the indexes across multiple sites.
Custom PropertiesAdditional key-value pairs for dotAI configuration.

Once installed and configured, the dotCMS surfaces a variety of utilities. The section below provides a brief overview of each, and a link to further documentation.

Using dotAI

The dotAI feature includes several components, detailed separately:

dotAI ToolThe dotAI admin-panel interface can be found via Tools -> dotAI, allowing direct usage, index definition, and general configuration of the feature.
AI BlocksdotAI's integration with the Block Editor field provides the most straightforward way to get started generating content.
AI WorkflowsAI Workflow Sub-Actions permit a range of asynchronous automations utilizing AI — such as generating entire contentlets on demand.
AI ViewtoolThe AI Viewtool, accessible through $ai, allows AI operations via Velocity script.
API ResourcesREST API endpoints allow OpenAI operations to be performed headlessly.
