HOUR 0โ2: Find a $1,000 Idea in 10 Minutes
Prompt ( example of a copy-paste):
โIโm a student who gets distracted by TikTok and YouTube while studying. Suggest 10 simple Chrome extension ideas that solve this in under 100 lines of code. Include monetization ideas.โ
To write an effective prompt, clearly state your desired outcome, provide specific context or role (e.g., โAct as an expert chefโ), and include any constraints or format requirements. The more precise and structured the prompt, the better and more consistent the AIโs response will be.
Top Idea We Picked:
“Focus Extensions” โ Block distractions + play lo-fi beats in one click.
Validation (5 mins):
- Search Chrome Web Store โ 3 similar tools, but none combine blocks + music
