What people got done with Devin.https://agenticfeats.com/enhttps://agenticfeats.com/c/unanswered-email-tracker-with-devin/https://agenticfeats.com/c/unanswered-email-tracker-with-devin/Devin wrote a Gmail function to find emails needing a reply, built a front end, tested it locally, and deployed it to a public link. Result: Within one night Devin produced a working unanswered-emails interface using the Gmail API, after the author wrote the authentication code themselves. Evidence: Shown.
