About AI Grammar & Paraphraser
Our AI Grammar & Paraphraser uses LanguageTool API for advanced grammar checking and Hugging Face's PEGASUS AI model for intelligent paraphrasing. The grammar checker analyzes your text for spelling, grammar, style, and punctuation errors with context-aware suggestions.
The AI paraphraser uses transformer-based deep learning to generate natural-sounding alternatives while preserving meaning. Both features require internet connection to access powerful cloud-based AI APIs. Note: Your text is sent to external services for processing.
How does AI Grammar Checking work?
The tool uses LanguageTool API, a powerful open-source grammar checker with advanced AI algorithms. It analyzes your text for spelling errors, grammar mistakes, style issues, and typographical errors. The API examines sentence structure, word usage, and context to provide accurate corrections and suggestions.
How does AI Paraphrasing work?
The paraphrasing feature uses Hugging Face's PEGASUS model (tuner007/pegasus_paraphrase), a state-of-the-art AI model specifically trained for paraphrasing. It understands context and generates natural-sounding alternatives while preserving the original meaning. The first use may take 20-30 seconds as the model loads, but subsequent uses are faster.
Is my text private and secure?
Your text is sent to external APIs (LanguageTool and Hugging Face) for processing. Both are reputable services with privacy policies, but the text is transmitted over the internet. LanguageTool does not store your text permanently. If privacy is a critical concern, avoid entering sensitive information.
What types of grammar issues can it detect?
The LanguageTool API detects: spelling errors (misspellings, typos), grammar errors (subject-verb agreement, tense issues, etc.), style issues (wordiness, redundancy), punctuation errors, capitalization mistakes, commonly confused words, and many more. It supports advanced context-aware checking for accurate results.
How does the paraphrasing feature work?
The paraphraser uses Hugging Face's PEGASUS model, a transformer-based AI trained specifically for paraphrasing. It analyzes your text semantically and generates natural alternatives while keeping the meaning intact. For longer texts (>200 characters), it uses a simpler synonym-based approach. The AI model may need 20-30 seconds to load on first use.
What is the Grammar Score?
The Grammar Score is a percentage (0-100%) that represents the overall grammar quality of your text. It's calculated based on the number of issues found relative to text length. Higher scores (80%+) indicate excellent grammar, medium scores (60-79%) suggest some improvements needed, and lower scores (<60%) indicate multiple issues requiring attention.
Does it work offline?
No, this tool requires an internet connection to access the LanguageTool API for grammar checking and Hugging Face API for AI paraphrasing. Both services run on cloud servers to provide powerful AI capabilities without requiring large downloads on your device.
