About this app
AI comes up at dinner, at work and in the news, and most of us nod along. Nobody explains it from the beginning. Data to AI does, five minutes at a time.
It starts with the data your phone makes before you get out of bed and ends with how chatbots and your feed work. No math background, no coding.
Four friends try to figure out why Maya's video #14 blew up. Over 24 modules they clean up a messy export, find an outlier, run a fair test, build a model that flops, and finally trace the answer. You pick up each idea right when they need it, then try it yourself.
WHAT'S INSIDE
• 24 modules and 96 five-minute lessons, in seven parts
• Something to play with in every lesson: sort a spreadsheet, draw a line through used-car prices, sort points into groups, guess the next word like a chatbot does
• A Lab with real public datasets and four tools: a table, charts, line fitting and grouping
• A Talk Card from every lesson, one sentence you could say at dinner
• A Dinner Table Challenge in every module, a question to ask whoever's across the table
WHAT YOU'LL LEARN
Where your data goes. What counts as data. Spreadsheets and cleaning. Asking fair questions. Averages that lie, spread and percentiles, chance and samples. Correlation vs. causation. Honest charts. Fair tests. Telling a story with data. How machines learn from examples. Predicting numbers, sorting into categories, finding hidden groups. Overfitting. Bias. Neural networks. How chatbots work. How your feed works. AI in the real world. And a finale where you grab a free dataset and explore it yourself.
FREE TO START
Part I (Modules 1 to 3) and the used-car lesson are free. One payment unlocks the other 21 modules, every Lab tool and every dataset. No subscription and nothing to cancel. The purchase goes through Google Play, and it comes back on a new phone signed in to the same Google account.
NO ACCOUNT, NO ADS, NO TRACKING
There's nothing to sign into. Progress and cards stay on your phone. No analytics, no ads, and it works in airplane mode.
BUILT FOR
Curious teens, and the parents and grandparents who want to keep up with them.
Data to AI is a Pettigrew Lab project. Joel Pettigrew spent twenty years building data and AI products and wanted his own kids to understand how the stuff works. This is the course he wished existed.
