GDG Compitas is a mobile onboarding app for newcomers to Google Developer Groups. It does two things: first, it uses Gemini to generate personalized learning roadmaps — you pick your level and goal (learn AI, understand organizer roles, run your first event, find sponsors…) and Compi builds a step-by-step path with official Google resources like Firebase, Flutter, ML Kit, and Codelabs. Second, it has an interactive events map where organizers publish their meetups by city and anyone can discover

“I thought building the app would be the hard part and publishing it would be one click. It was the opposite, the app flowed, and I almost got stuck on a billing screen. Turns out "free" was hiding behind the button that wasn't the obvious one.”

Codelab Compass helps GDG organizers plan a workshop without starting from a blank page. Answer six questions — audience level, topics, time available, machines, goal, start time — and you get a full agenda: timed blocks, an official Google codelab for each one, and a file ready for your calendar (.ics, Google Calendar, Markdown). Two rules: no session over 2 hours, no block over 45 minutes. One HTML file, no build. It works without AI; with Gemini it also writes facilitator notes.

“The best decision was the boring one: making it work without AI. Mid-test, Gemini returned a 503. The app didn't break — it built the agenda with its own rules and kept going. I assumed it was my API key. It was Google running out of capacity for that model. Connecting a model is easy. Deciding what happens when it doesn't answer is the real work.”

Transformando o que sobra em oportunidade Todos os dias, pessoas e empresas têm objetos em bom estado que não usam mais — móveis, eletrodomésticos, roupas, livros, materiais escolares e tantos outros itens. Ao mesmo tempo, pessoas e organizações precisam exatamente desses recursos. O problema é que quem quer doar nem sempre sabe para quem doar, e quem precisa nem sempre sabe onde encontrar. Nossa proposta é criar uma plataforma que conecta diretamente doadores, pessoas que precisam e ONGs, tor

“Vivemos em uma sociedade em que muitas vezes aquilo que deixa de ter valor para uma pessoa continua tendo enorme valor para outra. Um móvel parado em uma garagem pode ser o primeiro móvel de uma família. Um computador que não usamos mais pode representar uma oportunidade de estudo. Uma roupa esquecida no armário pode ser exatamente o que alguém precisa.”

It's the building blocks for the future of product recommendations. Users complete a quick body-profile questionnaire to generate a customizable 3D mannequin, view estimated measurements, explore clothing options, and receive size recommendations from a sample garment catalog.

SecondLook makes fashion resale as simple as showing an item. Instead of starting with a listing form, it uses multimodal AI to see, listen, understand condition, generate the listing, research the market, and recommend a price. By removing the friction of resale, SecondLook helps fashion move from one person’s past into another person’s style. https://drive.google.com/file/d/1M-gB_qWJuZUL2FXceOGHevAX9Xb6tVnU/view?usp=drive_link
