🚀 Why I built this
Like most developers, I’ve spent way too much time searching for that one regex pattern that works. And writing SQL queries from scratch every time can get repetitive too.
So, I decided to create a simple, AI-powered developer tool that can do both — instantly.
👉 Dev Brains AI
It’s a collection of free AI tools that help developers save time on everyday coding tasks.
🧩 Current tools on the site 🔹 AI Regex Generator
Describe what you want — and it writes the regex (with explanation).
Examples:
“match a valid email address”
“extract numbers from a string”
“check if string starts with ‘abc’”
Result → regex + human-readable explanation.

🔹 AI SQL Query Generator
Write your query in plain English, and it outputs real SQL instantly.
Examples:
“Select top 5 users by revenue”
“Find all orders from last 30 days”
It supports MySQL, PostgreSQL, and SQLite-like syntax.

🧠 How it works
I used:
Next.js + TailwindCSS for the UI
Open-source AI models from Hugging Face (no paid API keys)
Node.js serverless functions for generation
Deployed on Vercel (super fast and free)
Each request uses a small, open model that runs under 2 seconds, so you get results instantly.
💡 What’s next
I’m working on adding:
🧾 JSON formatter with AI explanations
🪄 Code comment generator
⚙️ Log pattern detector for DevOps users
If you have ideas for more tools, I’d love to hear them in the comments.
⚡ TL;DR
Free AI-powered Regex & SQL Generators
No signups, no limits
Uses open models (not OpenAI API)
Fast and ad-supported
