What it is
A Chrome extension that bulk-downloads Gmail attachments to a ZIP or straight into Google Drive. Gmail has never offered this; people were opening every email one by one. Recruiters, finance teams, ops folks: anyone who lives in attachments.
Why I built it
I saw the pain on X and could see the whole build clearly in my head. But the real reason: I wanted to prove I could build a complete product without writing the code by hand, just directing the AI in English. This was the first one. It worked.
What happened
Published to the Chrome Web Store, which turned out to be the entire acquisition channel, because that’s where people search when they have this exact pain. A long, generous free tier built the user base; restricting it later and making Pro the real path scaled the revenue. The numbers are public and Stripe-verified, updated live. I’d rather show you the dashboard than adjectives.
I knew Google could ship this natively any day. A year and a half on, they haven’t. Competitors showed up instead, which reads as validation.
What I learned
Boring utilities on huge platforms beat clever products in empty markets. Distribution was the listing, not the marketing site. The site’s actual job became getting cited by LLMs when people ask AI for a solution. And passive revenue, even modest, changes how you think about everything else you build.
