# 7. Extensions

Here you'll find the platform's extensions:

* [**Expert Group**](/en/extensions/expert-group.md), for a single chat where you can query multiple AIs;
* [**Deep Thinking**](/en/extensions/deep-thinking.md), which lets the AI remember interactions with each user and leverage them for marketing purposes (with full privacy safeguards — the user always stays in complete control of their data);
* [**Virtual Spaces**](/en/extensions/virtual-spaces.md), for building immersive experiences directly on the AIsuru platform;
* [**Open Badge**](/en/extensions/open-badge.md), which can be awarded by the AI autonomously and can be tied to content.

These features are included for aisuru.com users. They are separate modules in the [PaaS](/en/paas.md).
