About AI Learning Gym

AI Learning Gym is a free collection of browser-based tools built for developers, students, writers, and anyone who needs a quick utility without the hassle of signing up or installing software. Everything on this site runs directly in your browser — there's no server processing your input, no account required, and nothing to download.

The idea came from a simple frustration: searching for a basic tool like a word counter or JSON formatter and landing on a page bloated with ads, pop-ups, and login walls. We wanted a clean, fast alternative where you can just open the tool and use it.

What we offer

The site covers a range of everyday needs across several categories:

• Text tools — word counter, case converter, diff checker, markdown editor, lorem ipsum generator, text-to-speech, font generator, and AI content detector
• Developer utilities — JSON formatter, Base64 encoder/decoder, password generator, QR code generator, image resizer, and WhatsApp link creator
• Calculators — loan amortization, tip splitter, unit converter, age calculator, BMI, BMR/TDEE, and sleep cycle planner
• Productivity tools — Pomodoro timer, online clock with world time zones, stopwatch, and countdown timer
• AI tools — token counter, prompt builder, and image prompt generator for Midjourney, DALL-E, and Stable Diffusion
• Screen utilities — color picker and dead pixel tester

Privacy

Every tool on this site processes your input locally in your browser. When you paste text into the word counter, enter numbers into the loan calculator, or generate a password, that data never leaves your device. We don't log your inputs, and we don't sell data. You can read the full details in our Privacy Policy.

Accuracy

We try to keep calculations accurate and formulas up to date. The loan calculator uses the standard amortization formula. The BMR calculator uses the Mifflin-St Jeor equation. The sleep calculator is based on the 90-minute sleep cycle model. If you notice an error in any tool, please let us know via the contact page.
