## Free tools for creators and brands

**Category:** New Feature
**Published:** Oct 20, 2026 at 10:46 PM

Collabios is a marketplace where brands and creators plan influencer partnerships. Next to it we keep a set of free tools for anyone who works with creators. This first entry explains what is there today.

There are more than a dozen free tools, and you do not need an account to use them. The engagement rate calculator compares the likes and comments on a creator's posts with the size of their audience, which is useful when you review a profile before starting a conversation. The EU disclosure generator helps creators draft the wording that marks a post as a paid partnership.

You can try the [engagement rate calculator](https://collabios.com/en/tools/engagement-rate-calculator) directly, or browse the rest of the tools from the [Collabios home page](https://collabios.com/en). We will post here when we add new tools or change how the existing ones work.
