  I've been working on Recall for a while now, it had some initial traction in the beginning which has since died down now.

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client.
