PDF Grammar, Spell Checker & Writing Style Auditor
The RiazHub Browser-Based PDF Grammar, Spell Checker & Writing Style Auditor is a privacy-first digital utility designed to analyze manuscripts, academic papers, reports, and dual-language tax invoices directly inside your web browser. Without uploading your confidential PDF files to any remote cloud server, our client-side linguistic engine detects misspelled words, subject-verb mismatches, article errors, punctuation flaws, wordy phrases, and passive voice structures. It calculates real-time Flesch Reading Ease scores and Flesch-Kincaid Grade Levels while providing intelligent BIDI reordering for Arabic and English dual-language invoices. Generate printable PDF audit reports, export clean corrected text files, or copy error summaries with instant clipboard feedback.

PDF Proofreading & Grammar Best Practices
🔒 100% In-Browser Privacy Guarantee▼
All PDF text extraction, sentence tokenization, spell checking, and grammatical pattern evaluations run strictly inside your web browser. Your uploaded manuscripts, invoices, and confidential PDFs are never transmitted to external cloud servers.
🌐 Universal Multilingual & BIDI Support (All Major Languages)▼
This utility includes intelligent character pattern matching for English, Arabic, Spanish, French, German, Italian, Portuguese, Russian, Chinese, Japanese, Turkish, Hindi, Urdu, and more. Dual-language invoices and contracts are formatted automatically for natural reading.
📊 Understanding Multilingual Readability Scores▼
The Flesch Reading Ease score rates text readability on a 0-100 scale. For non-Latin or dual-language documents containing formatted line items or tables, sentence metrics are calculated based on line breaks, structural punctuation, and script-aware word bounds.
