# Common knowledge

## What is common knowledge

In Rememberizer, registered users **(publishers)** can select their uploaded documents through mementos and share them publicly as common knowledge. Other users **(subscribers)** can access this public knowledge and add it to their own resources.

By contributing their data, other users can collectively enhance the available information on the common knowledge page. This collaborative approach allows all users to access a richer data source, thereby improving the learning capabilities of their AI applications.

## Add public common knowledge

In order to subscribe a common knowledge to your resource, follow the instructions below

* On navigation bar, choose **Personal > Common Knowledge**. Then, you will see the public common knowledge page.

* Then, look for the common knowledge you want to subscribe. You can look up the knowledge by typing the knowledge's name on search bar. You can optionally choose the filter option next to the search bar.

## Create a common knowledge

For detailed instructions of creating and sharing a common knowledge, visit this page [Registering and using API Keys](/developer-resources/integration-options/registering-and-using-api-keys.md).

{% hint style="info" %}
Common knowledge is built on the foundation of [Mementos](/personal-use/personal/mementos-filter-access.md), which allow you to control exactly which documents are shared. Once created, developers can access your common knowledge through APIs to build custom applications or integrate with [LangChain](/developer-resources/integration-options/langchain-integration.md) and [OpenAI GPTs](/developer-resources/integration-options/creating-a-rememberizer-gpt.md).
