Built by Divit

PrakharOnline is a free, browser-based platform built and maintained by Divit as a personal project. It started as a place to host a few tools and has grown into a full AI-powered platform — an adaptive Class 7 CBSE learning system, AI tutor, productivity suite, developer tools, shopping hub, and an original platformer game — all completely free.

Why it's free

PrakharOnline started as a way to learn web development by building useful things. Everything here is free because it was built for fun and to be genuinely helpful, not to make money. There are no ads and no premium tiers.

Creating a free account lets you sync your notes, tasks, flashcards, tutor chats, learning progress and shopping wishlist across devices. The account is optional — all features work without one.

Technology

The site is built with HTML, CSS, and vanilla JavaScript — no frameworks. The AI features use the Groq, Google Gemini and Mistral APIs. Shopping price data uses SerpApi. The adaptive learning engine (mastery model, spaced repetition, question bank) is custom-built and runs entirely in the browser. All code is written by hand and runs on a standard web host.
