The interesting data is about people.

A place to practise disagreeing well. Pick a contested question and the position you want to understand, and an AI argues the strongest honest case for it: it holds its ground under pressure, concedes points that are true, names whether each disagreement is about values or facts, and never invents a statistic or argues against strong evidence. It never asks what you believe. Success is not a changed mind but less hostility towards the people who hold the view.

An LLM-refereed multiplayer business simulation for MBA classrooms. The engine treats each industry as data, so a professor can author a scenario in plain English instead of reverse-engineering a formula.

A voice-first dating platform with a deliberately anti-addictive design: voice and photos only, five conversations maximum, no paywall. Matches come from multimodal embeddings rather than preference forms.

A single-player geopolitical strategy game in the spirit of Balance of Power. Claude writes the briefings, resolves your free-text moves and plays the rival powers across twenty turns, under constant escalation risk.

Photograph a meal and AminoLens breaks it into all nine essential amino acids, shows which one is holding your protein back, and tells you what to add, without breaking a vegan, vegetarian or allergy rule. Requirements scale with your weight, age and training load from WHO/FAO/UNU reference patterns; amino acid data comes from USDA FoodData Central.

A prospect research tool for fundraising teams, over openly-licensed 360Giving grants data. The money question — who could give more, or start: it finds the funders who back organisations like yours but not yet you, estimates what they might give and the gap, and flags where your own funding is dangerously concentrated. The relationship question — how to actually reach them: a language model reads public pages and maps the human network around a prospect, the board seats and shared causes that open a door. Every grant figure traces to a filed source; the network to public record.

The Headwinds engine, run as a corporate team session. Three to eight teams each steer a rival company through timed rounds of strategy under competitive pressure, then leave with a strategic profile — risk appetite, time horizon, innovation orientation — and a facilitator debrief. A mini-MBA afternoon for any team, from the exec floor to engineering; in London or remote.

Clean equity datasets assembled from free public sources: SEC EDGAR filings, earnings-call transcripts, prices and macro series, behind idempotent ingestion and a React analysis layer.

Every division in the Commons, turned into a map of the House. MPs are placed by the cosine similarity of their voting records, filterable by policy area, and rebellion is scored in bits: defying a party that split 312–2 counts for far more than defying one that split 160–154.

An AI vault for household paperwork. Photograph a document and a single vision call reads it, classifies it and pulls out the fields for you to confirm.

Conjoint analysis as a three-minute game. Choose who you would rather date and an elastic-net model infers which of roughly 119 attributes are actually driving you, as opposed to the ones you would claim.

A wedding platform that runs the admin, then gets the guests talking on the day. The organising is free: RSVPs, guest list, dietary needs, a drinks survey, schedule and travel. Its paid social layer is where the AI lives: it embeds each guest's relationship to the couple and the style of their photo into an interactive graph that seats the room by affinity, then a find-the-guest bingo of secret facts, with a live leaderboard, turns those inferred links into real introductions. AI creates the map; the guests create the connection.

Every country as a dot, moving between kinds of government year by year from 1789, drawn from the V-Dem record built on surveys of thousands of country experts. Group by regime type, by how the head of state got the job, or by electoral democracy score, and size by population or GDP. Nothing is simulated: a dot moves only when the record changes.

Photograph a plant and find out whether it is toxic to your cat. Pl@ntNet identifies the species, then a layered matcher checks it against the ASPCA list of 983 plants, by species, then genus, then near spelling, and every verdict shows how it was matched and how confident it is. Free, with no signup.

A generative instrument: a point cloud that sleeps in silence and wakes to sound. Stacked oscillators drive a looping plume of light; the microphone breaks the loop, so the room's noise reshapes it as it plays. Drive it by hand, by constrained chance, or by voice.

A browser instrument for learning a synthesiser by seeing it. Plug in a microKORG and watch the waveform, spectrum and spectrogram react as you turn the knobs, with pitch-locked oscilloscope and harmonic markers. Record samples and layer them into repeating or Steve Reich-style phasing patterns. Everything runs in the browser.
