PreetBeacon is India's most comprehensive free Student OS — a platform built by engineering students, for engineering students. It offers 30+ AI-powered tools covering academics, career, daily utilities, and more. No login. No paywall. Just pure knowledge, freely available to everyone who needs it.

Preet Yadav — a CSE student from Jaunpur, Uttar Pradesh — built PreetBeacon out of frustration with the lack of quality free resources for engineering students. He wanted every student, regardless of their financial background, to have access to the best tools. That dream became PreetBeacon.

Yes — completely, unconditionally free. Every single tool. Every single resource. No hidden fees, no premium tiers, no subscriptions. PreetBeacon is sustained by non-intrusive Google AdSense ads, which keep the lights on without ever costing you a rupee.

Absolutely not. No registration, no email, no phone number. Open the site, pick a tool, and start using it instantly. We believe your time is precious — so we never waste it on sign-up flows.

Three things: (1) Everything is free with zero login. (2) It's purpose-built for Indian engineering students — especially AKTU — not a generic global tool. (3) It's built by a student who lived the struggle. The tools aren't just features; they're solutions to real problems Preet faced himself.

Through Google AdSense — tasteful, non-intrusive ads that support server costs and development. We never sell your data. We never show pop-ups that ruin your experience. Ads are the smallest possible trade-off to keep everything free forever.

100%. We don't collect personal data, don't store your inputs, and don't sell anything to anyone. Your privacy is sacred. The site runs on HTTPS, and we follow best practices for web security.

Yes — every page is fully responsive, tested on Android and iOS, tablets, and all screen sizes. We know most students use their phones, so mobile experience is a top priority — not an afterthought.

While many tools are built with AKTU in mind, most AI-powered tools — AI Tutor, Notes Generator, Resume Builder, Paraphraser, etc. — work for any university. We're continuously expanding support for more institutions across India.

Yes! Share feedback, report bugs, suggest features via the Feedback page. If you're a developer or content creator who wants to collaborate, reach out through the Contact page. Community is the heart of PreetBeacon.

Assignment Writer generates complete, well-structured academic assignments from your topic and requirements. It writes in a natural academic style — not robotic AI text. Use it as a starting point, add your personal touch, and submit with confidence.

Paste any text and the AI rewrites it in a fresh, natural way — removing plagiarism while preserving meaning. Multiple tone options (formal, casual, academic). Essential for assignments, reports, and any written work you want to make uniquely yours.

Upload a photo of handwritten notes and the AI converts them to clean digital text. Supports Hindi and English. Works on messy handwriting too (mostly!). Great for digitizing old notes, sharing content, or running a quick search through your notes.

PreetBeacon uses best-in-class AI APIs to power its tools. The specific model may vary by tool, but all are carefully selected for accuracy, safety, and performance in academic contexts. The experience is optimized specifically for students, not general chat.

We aim to keep usage generous and free. Some tools may have reasonable limits per session to ensure fair access for all students. These limits are designed to support typical student usage — most students will never hit them during normal study sessions.

Yes! The AI Tutor can explain coding concepts, debug logic, explain algorithms, and walk through programs step by step. It's especially helpful for data structures, algorithms, DBMS queries, and programming lab assignments.

It's the story of Preet Yadav — why he built PreetBeacon, what challenges he faced, and what drives him to keep building for students. It's an honest, personal story that many engineering students will deeply relate to.

Visit the Feedback page — share a feature request, bug report, or just words of encouragement. Every single submission is read by Preet personally. Your voice genuinely shapes what gets built next.

A complete, searchable directory of every tool on PreetBeacon — organized by category. The best starting point if you're new, or if you want to discover tools you haven't tried yet.

That is the promise and the mission. As long as PreetBeacon exists, the core tools will always be free for students. Education should never have a price tag — and that belief is baked into everything we do.

Regularly. Preet and the community actively update resources as university syllabuses change, new tools are developed, and student feedback comes in. If something is outdated, report it — it'll be fixed fast.
