About Niraiya: The AI-Powered Excel Password Unlocker

The Story Behind Niraiya

It started with a forgotten password. Late one night, I was locked out of a crucial Excel file. The password was on the tip of my tongue, but I just couldn't get it.

I tried the usual tools, but they were either expensive, slow, or wanted me to upload my private data to some unknown server.

I knew there had to be a better way.

So, I built Niraiya. It began as a personal project to solve my own problem, but it grew into something much bigger: a browser-based tool that respects your privacy while using smart AI to do the heavy lifting.

Our Mission: Privacy First

We believe you shouldn't have to choose between security and access. Our mission is to make password recovery accessible to everyone, without the risk.

Our approach is simple: your file stays with you.

We use advanced WebAssembly technology to look at the "lock"—the cryptographic fingerprint of your password—right in your browser.

We send that mathematical puzzle to our AI, solve it, and send you the key. We never see your rows, columns, or charts.

Solving the Real Problem

Losing access to a file is more than just an annoyance; it can mean missed deadlines for students or lost financial records for businesses.

Traditional "brute force" methods take forever because they try every random combination.

Niraiya is different. We know that humans create passwords in predictable ways—using names, dates, or simple phrases. Our AI is trained to recognize these patterns, which means we can often unlock a file in minutes, not days. And if a password is truly random and impossible to crack?

We'll tell you straight up, so you don't waste your time.

Smarter Technology

We don't rely on just one brain. We use a team of them. Our system orchestrates top-tier AI models like ChatGPT, Gemini, and DeepSeek.

They work together, each bringing different strengths to the table—pattern recognition, prediction, and optimization.

This multi-AI approach allows us to crack passwords that single models might miss.

And because we only process the encrypted hash, your actual document content remains completely invisible to us and our AI partners.

Earning Your Trust

We know that trust is earned, especially when it comes to security. That is why we are transparent about how we work.

We use bank-level 256-bit SSL encryption for all data transmission.

More importantly, we practice "data minimalism.". We don't store what we don't need.

Helping Real People

We have helped thousands of people get back to work.

From the graduate student panic-stricken over a locked thesis to the accountant needing last year's tax logs, we have seen it all.

These success stories are what drive us. We are here to provide a lifeline when you are stuck, offering a solution that is fast, affordable, and secure.

What's Next?

We are starting with Excel, but we aren't stopping there.

We are working on bringing this same privacy-first, AI-powered recovery to Word documents, PowerPoint presentations, and VBA projects soon.

We are constantly refining our algorithms, learning from every successful unlock to make our system smarter and faster for the next user.
