A developer going by the handle aitechgems on DEV.to recently documented their weekend experiment: building three free AI-powered tools from scratch in under nine hours combined. The project showcases how developers can rapidly prototype and ship useful tooling when they prioritize simplicity over feature bloat.
Tool One: The Quiz Generator
The first tool—a five-question quiz designed to recommend the perfect AI solution—took roughly four hours to build. According to the author, the key insight here was that people gravitate toward simple interfaces. By limiting the quiz to just five questions, they reduced friction and kept users engaged without overwhelming them with decision fatigue.
Tool Two: Prompt Improver
The second tool tackles a common pain point: lazy prompts. Users input underdeveloped prompts, and the system transforms them into something ten times more effective. This three-hour build focused on solving a specific, recurring problem that AI users encounter regularly. The lesson? Build for real workflows, not hypothetical ones.
Tool Three: Cost Calculator
The final tool lets users input their various AI subscriptions and calculates their monthly total automatically. Built in just two hours, this demonstrates how utility-driven tools with narrow scope can deliver immediate value without extensive development cycles.
Key Takeaways
- Simplicity wins—fewer features mean lower barrier to entry
- Free tiers convert better and attract initial users
- Solving specific pain points beats building generic solutions
The Bottom Line
This weekend project proves that you don't need weeks or months to ship something useful. Strip away the ambition, focus on one job per tool, and get it in front of users fast. The best dev tools often aren't the most complex—they're the most honest about what they do.
