Note: This is an advanced use-case.

If you plan to use the application across computers, you can store the cover letter snippets in the preconfigured MongoDB database or your own MongoDB database on

If you want to play around with the app, there is a preconfigured database URI string in the form field. Please be a good person or I will have to take it out. Also, after you are done trying out the app, delete your entries from the database to ensure that other users don't see your entries.

  1. Go to and sign up or log in.
