Playground
Things I've built on this site to try ideas out. Some are AI, most are just data the site already has, and all of them keep themselves up to date.
Jevworld
LiveA little pixel town that never stops. Eleven people, each born with a goal, and every choice any of them makes is Jev's: where to go, who to talk to, how it goes. They even argue about my predictions.
Jev
The decision model behind this site. Ask it typed questions and get calibrated probabilities back, not text.
Ask my writing
Ask a question and get a short answer from what I've written here, with links to where it came from.
Predictions
Calls I've made, dated and scored in public, with Jev's running odds on each.
2025 in review
My year as full-screen stories, like Spotify Wrapped, built from everything the site already knows.
Fitness
Running, riding and weights from Strava, and code from GitHub: this year against last.
Goals
This year's goals, in public, keeping score by themselves.
Crash watch
Is the stock market about to crash? Seven warning signs checked daily, and every big crash since 1929.
The notebook
Two AI-written notes a day on the companies I've backed, checked by Jev before they go live.
The AI build-out
Who's spending on AI data centres, where the money goes, who's getting it, and what I'm watching. Refreshed weekly.
Edtech
The education market in numbers: funding since the boom, the listed companies, AI in schools and who's buying whom. Refreshed weekly.
Portfolio map
Every company I've backed as a tile, shaded by how its share price is moving.
Stats
This site in numbers, rebuilt every day.
