Struggling to get users for my AI app

I've developed CoverAI, an advanced Android AI cover letter generation app. It offers unique features that are not present in any Google Play cover letter generation app like company-specific tailoring, resume integration, job posting info extraction and job search together with a minimalistic, user-friendly UI. But after 16 days of release the dau is from 1 to 6 (i even had to spend on ads) I would appreciate a feedback and advice on how to get the app more noticed https://play.google.com/store/apps/details?id=com.cover.ai
