# Ask HN: What apps are you building? > Source: > Published: 2026-07-28 02:37:56+00:00 I have created a whitelist only email service at Supertopsecret.com. Only addresses the user provides can get into the inbox. All else is blocked. Landing page is a spy theme and would be interested if people think it's too sarcastic/off putting. Thank you. Detailed comments can go to hq@supertopsecret.com (which I set up to be non-whitelist only). We are building an AI Agent Designer web app-Craftsman Agent which can turn prompts into ready to use 3D/2D design, such as a Tesla car wrap, a Perler Beads Pattern, etc. You can use "Generate a blue and white yacht", "Generate a Argentina Football Team Theme Car wrap or Perler Beads Pattern" to generate lego 3D blueprint, step by step assembly charts, etc.
