Black­wall

My own Gmail app for my PC. It sorts every inbox into Important, Everything else and Junk, tells me why each email is where it is, and looks like a computer screen from Cyberpunk 2077.

// 01The screen

Built to look like the in-game computers in Cyberpunk 2077: cyan frame lines, cut-corner tabs and the game's own fonts and colors.

Demo inboxEvery email in these screenshots is made up for this page. No real mail is shown.

ImportantAn email open, with Claude's short summary and the one thing I need to do.

Breach Protocol loading screen

While the first sync runs, the loading screen is the game's Breach Protocol hacking puzzle: a code matrix of 1C, 55, BD, E9, 7A and FF with a moving highlight, next to a segmented bar that fills as emails are sorted.

The name comes from the game too. There, the Blackwall keeps rogue AIs off the Net. Here, it keeps the junk out.

// 02How it works

A small Python server on my PC with the screen in its own window. It's a personal tool, so there's no download.

Sorting

  • Free rules go first: senders I've moved, Gmail's spam, people I've emailed before, and Gmail's promotions and social tabs.
  • Claude sorts what the rules can't, for a fraction of a cent an email, under a monthly limit I set.
  • Every email says why it's there. Move one and everything from that sender follows.
  • It never deletes, archives or changes anything in Gmail.

The look is inspired by the in-game computers of Cyberpunk 2077. Blackwall is my own personal project and isn't affiliated with CD PROJEKT RED.

// 03Privacy

The short version. The full policy covers exactly what's used and where it goes.

Everything stays on my PCSign-ins, the sorted list and opened emails live in a local database. There's no server of mine in between.
Read and send, nothing moreIt asks Google to read mail and to send only what I write and confirm.
Claude sees only what it needsThe sender, subject and start of an email it sorts, or the whole email when I press Summarize.
Nothing sold or sharedNo ads, no tracking, and nobody else uses it.
