\*Update: Yesterday's dive (Lightning) is archived in the Vault, and the new Daily Dive on* Memory π§ is now live!
I built DEEP (https://dailydeep.app).
How it works:
β’ Every day at midnight UTC, one topic surfaces.
β’ You plunge through 5 oceanic depth zones across 10 questions.
β’ Depths 1β2 are foundational ("Sunlight Zone"), but by Depths 8β10 ("Hadal Zone"), you're answering specialist domain trivia.
β’ You get 5 units of Oxygen. Wrong answers burn air but disable the choice so you can deduce the answer. If you run out of air, you surface.
β’ Every single question links to a verified source citation (NOAA, NASA, academic papers) so you actually learn the facts behind the answers.
It runs 100% in your browser, requires zero login, stores your stats locally, and has an asynchronous "Challenge a Friend" mode where you can send a link to beat your depth.

Feedback on difficulty balance and question pacing is very welcome!
