I'm a solo developer who built 42 free AI tools at simplylouie.com/tools. No signup required. Here's the real story.
Why $2/month when ChatGPT charges $20?
I spent 30 years in the car business. The tools people need — resume builders, budget planners, interview prep — are locked behind $20/month paywalls or buried in ads. I wanted to build something different.
Louie is named after my rescue Saint Bernard who spent two years alone and forgotten before learning to love again. That dog taught me something: the best things should be accessible to everyone, not just those who can afford it.
What I Actually Built
42 tools, all free, 3 uses per day:
Career: Resume Builder, Cover Letter Writer, Interview Prep, LinkedIn Optimizer, Pitch Generator, Meeting Notes Summarizer
Writing: Email Polisher, Social Post Creator, Bio Generator, Caption Writer, Story Generator, Email Subject Lines
Learning: Homework Helper, ELI5 Explainer, Quiz Generator, Flashcard Maker, Essay Outliner, Language Tutor, Translator
Life: Meal Planner, Workout Generator, Budget Helper, Decision Helper, Daily Boost
Fun (the ones people share): AI Roast Generator, Pickup Line Generator, Excuse Generator
Tech: Code Explainer, VIN Decoder, Trade-In Estimator, Loan Calculator, Home Value Estimator, Solar ROI Calculator
Try any of them: simplylouie.com/tools
The Tech Stack
- Backend: Node.js + Express
- Frontend: Vanilla HTML/CSS/JS (no framework bloat)
- AI: Claude API (Anthropic)
- Database: SQLite
- Hosting: DigitalOcean ($50/month)
- Design: Custom CSS design system — warm cream/amber palette inspired by Saint Bernard fur colors
- Payment: Stripe ($2/month, 7-day free trial)
Each tool page is a self-contained HTML file with inline styles and JS. No build step. No webpack. No React. Just files that load fast.
The Honest Numbers
Let me be real:
- Users: 4
- Paying: 1
- MRR: $29
- Monthly server cost: ~$50
- Revenue to animal rescue so far: $14.50/month
I'm operating at a loss. But the product works, the tools are live, and the mission is real.
The Business Model
$2/month gets you unlimited access to all 42 tools + a chat AI assistant + a virtual rescue puppy that grows as you use Louie.
50% of all revenue goes directly to animal rescue organizations.
No ads. No data selling. No VC investors demanding 10x growth.
Why I'm Sharing This
Because I think the indie dev community understands building something real over building something that looks impressive on a pitch deck.
I'm not asking for money. I built something I'm proud of, and I think some of you might actually find it useful.

If you build something, build something that matters. And if you can, rescue a dog while you're at it. 🐾
