Overview

Meet your daylight regret engine

SADS is a sleek psychological gadget that tracks your exposure to light, your exposure to emails, and the gap between the two. Instead of pretending everything is fine, it delivers a calm, data-driven verdict: you probably should’ve gone outside.

Combining weather feeds, calendar events, and your growing collection of ignored reminders, SADS generates a personalized, gently mocking narrative of your winter days.

Features

What SADS™ does to you

  • Hyper-local regret forecasting – morning notifications detail exactly how much light you missed and what you were doing instead.
  • Regret-based mood reconstruction – rebuild your week through graphs of coffees, meetings, and unrealized walks.
  • Judgmental artificial dawn – a soft white glow that quietly asks, “Why didn’t we start this earlier?”
  • Daylight Regret Index (DRI) – a single mysterious number that feels important and slightly accusatory.
  • Seasonal story mode – a calm narration of your winter as if voiced by a disappointed but loving documentary host.
Use cases

Who is this for?

SADS is ideal for:

  • People who keep saying “I’ll go outside after this email.”
  • Remote workers who haven’t opened their blinds since mid-October.
  • Anyone who wants quantified self-loathing, but cozy.
  • Advent participants who suspect the Algorithmic Toucan is right about the December Grind.

Use responsibly. If SADS makes you laugh, that’s working as intended.

Available as a limited-run Advent artifact in the Structured Derangement collection.
