8 Apps in 15 Minutes? Gemini Canvas Makes It Possible

Gemini Canvas lets you build real, working apps, games, and dashboards without writing a single line of code -- and it's free for everyone. In this video, I'll walk you through 8 hands-on demos so you can see exactly what's possible and start building your own projects today.

We're covering a ton of ground here. You'll see how to create a personal budget planner, turn a plain spreadsheet into an interactive executive dashboard, build a website powered by NotebookLM research, chain Deep Research into an instant quiz, build a playable Space Invaders game, design infographics, explore a 3D solar system, and clone a Pomodoro timer app. I also share a quick personal story about how I used Canvas to solve a real problem for a teacher in about five minutes. Whether you're a teacher, student, or just someone curious about what AI can actually do, there's something in here for you.

Prompts used in this video:

1. Budget Planner App
PROMPT: Create a smart personal budget planner app. Include categories for income and expenses with preset options (rent, groceries, utilities, entertainment, subscriptions, transportation). Add real-time calculations showing total income, total expenses, remaining balance, and a savings rate percentage. Include a pie chart showing spending breakdown by category. Add alerts that turn red when expenses exceed income. Make it visually clean with a modern dark theme.

2. Spreadsheet Dashboard
PROMPT: Analyze this data and create an interactive executive dashboard. Include: a revenue trend line chart by quarter, a bar chart comparing product categories, a regional performance breakdown, KPI cards showing total revenue, growth rate, and top product. Add dropdown filters for region and product category that update all charts in real time. Use a clean, professional dark theme.

3. Deep Research Topic (customize this)
PROMPT: Research the history and science of sleep -- why we need it, sleep stages, and common myths.

4. Space Invaders Game
PROMPT: Create a retro-style space invaders game with a synthwave neon aesthetic. Use bright pinks, cyans, and purples on a dark background. Include a player ship at the bottom that moves with arrow keys and shoots with spacebar. Rows of alien enemies that move side to side and gradually descend. Add a score counter, lives display, particle effects when enemies are destroyed, and increasing difficulty per wave. Make it fullscreen and polished.

5. 3D Solar System
PROMPT: Create an interactive 3D solar system visualization using Three.js. Show all 8 planets orbiting the sun at proportionally different speeds. Each planet should be the correct relative color. Add the ability to click on any planet to see its name, distance from the sun, and one fun fact. Include a star field background. Add controls to speed up or slow down the orbital animation. Make the camera orbit-able with mouse drag.

6. Pomodoro Timer
PROMPT: Create a Pomodoro timer app with these features: 25-minute work sessions and 5-minute breaks, a large circular countdown timer with smooth animation, session counter tracking completed pomodoros, a task list where I can add what I'm working on during each session, sound notification when timer ends, and a daily statistics summary showing total focus time. Use a calming minimal design with soft blues and whites.
