How can I set up a system where specific words are automatically linked to a glossary definition?

[Joao Callegaro]

I've set up a Sales Glossary with a bunch of terms, and my idea is that whenever someone types those terms in Confluence, they would automatically link to their definitions in the glossary. I did come across a plugin that seems like it could work (Smart Terms), but I'm also curious if there are any other methods, maybe even free ones, to make this happen. Any suggestions or insights are appreciated! Thanks.
