Show HN: Followup Reminder – AI that drafts follow-ups for unanswered emails

Hi HN,

I'm Guillaume and I built Followup Reminder, a tool that automatically drafts follow-up emails for messages that didn't get a response. It's built with Python and hosted on Microsoft Azure.

Originally built for salespeople, I realized it's useful for anyone who sends important emails and forgets to follow up: freelancers, recruiters, founders, etc.

It checks your sent emails from 5 days ago, detects if they were replied to, and, if not, creates a pre-written follow-up in your drafts using AI, so you can review and send it in one click.

There's a short demo video below, and you can try it out for free.

I'm still validating whether this solves a real problem for enough people, and any feedback would be hugely appreciated. You can reach me at gs@airgen.io. Thank you!
