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 directly, or browse the rest of the tools from the Collabios home page. We will post here when we add new tools or change how the existing ones work.
