Niraiya.com is an online service focused on helping people recover or unlock passwords for Microsoft Excel files using privacy-oriented, AI-powered technology.
Unlike traditional brute-force tools or full file upload services, Niraiya focuses on privacy-first recovery using multiple AI engines.
🔑 What Niraiya Does
- AI-powered Excel Password Recovery: Niraiya uses advanced artificial intelligence models (including systems like ChatGPT, Google Gemini, and DeepSeek) to analyze encrypted metadata from locked Excel files and predict the likely password.
- Browser-based Processing: Your Excel file does not get fully uploaded to their servers. Only cryptographic metadata (not your actual content or data) is processed to help recover the password. This improves privacy and minimizes exposure of your file.
- Privacy-first Approach: Because processing is done with encrypted hashes and not the full file, personal or business data remains on your device and encrypted during recovery.
⚙️ How the Technology Works
- Local Extraction: In your browser (using WebAssembly), a summary of the encrypted parts of your Excel file is read.
- AI Analysis: The summarized encrypted data is sent to AI systems that generate and test likely password candidates based on common human password patterns.
- Multi-AI Collaboration: Combines several AI models (pattern recognition, optimization, and refinement) to improve chances of recovery.
🔍 How Niraiya’s Password Recovery Works
🧠 Multi-AI Tech Stack
Niraiya uses three AI engines together to improve accuracy and speed:
| AI Component | Role in Recovery |
| ChatGPT | Predicts likely password patterns based on human traits like names, dates, words, etc. |
| Gemini | Optimizes computing by ranking probable candidates and reducing unnecessary checks. |
| DeepSeek | Learns in real time from tested guesses to improve future attempts. |
💡 This collaborative approach helps get results faster than brute-force or random attempts.
🧩 Step-by-Step Recovery Process
- Upload Your Excel File You select the encrypted Excel file in your browser — no full content upload.
- Extract Encrypted Metadata Locally A .Net Core Blazor WebAssembly code in your browser extracts only the encrypted hash, which reveals nothing about your actual content.
- AI Analysis on Server The encrypted information goes to the AI engines to generate and test possible passwords.
- Receive Recovered Password If successful, you preview the result and pay only after confirming access.
- Automatic Data Deletion Temporary data and logs are deleted immediately once the process completes.
💡 Key Features
- Quick Recovery: Many passwords can be restored in minutes rather than hours using this multi-AI method.
- Privacy & Zero-Knowledge: The service claims it never accesses your actual data or full file contents.
- Success-Based Payment: You often pay only if the password is successfully recovered, and they offer a money-back guarantee if they can’t unlock your file within a certain period.
💰 Pricing & Refund Policy
| Aspect | Details |
| Success-Based Billing | You only pay once a password is successfully recovered. |
| Refund Guarantee | 100% cash-back if recovery fails. |
| Refund Timeline | Refund processed within ~3–5 business days if eligible. |
