Released my first chrome extension (Selkofy)

I recently released Selkofy, a language learning extension that allows you to highlight any text in your browser and get a contextual breakdown of the sentence.

It's my first extension, I haven't started marketing it yet because I'm about to put some minor improvements into the review process, relating to the on boarding of new users, but it'd be great to get tips from people on what works well with marketing etc.

I'm thinking about paid social media posts but the desktop nature of extensions makes me a bit unsure.
