A grammar analyzer scores your writing across multiple style dimensions — passive voice usage, wordy phrases, weasel words, cliches, and adverb overuse — then highlights each issue directly in your text so you can fix what matters most.

How to Use the Grammar Analyzer
The Grammar Analyzer goes beyond spell-check. While spellcheckers catch typos and basic grammar mistakes, this tool reveals the stylistic patterns that separate weak writing from strong writing — even when every sentence is technically correct.
Step 1: Paste Your Text
Copy any piece of writing — an email, essay, blog post, cover letter, or report — and paste it into the text area. The analyzer works best with at least 100 words so it can calculate reliable percentages. Enable real-time mode to see scores update as you type, or click "Analyze Grammar" for a single-pass analysis.
Step 2: Read Your Highlighted Text
After analysis, your text appears color-coded below: red underlines mark passive voice constructions, orange marks wordy phrases that could be shorter, yellow marks weasel words, purple marks cliches, and blue marks adverb overuse. Hover over any highlighted word or phrase to see the specific issue and a suggested fix.
Step 3: Check Your Dimension Scores
Six scoring dimensions each receive a PASS, WARN, or FAIL rating. A 100% score is not the goal — passive voice has legitimate uses, adverbs sometimes add precision, and some wordy phrases carry nuance. Use the scores as a diagnostic: if Grammar Clarity fails, focus your revision on the highlighted passive sentences. If Conciseness scores poorly, scan the orange-highlighted wordy phrases first.
Step 4: Prioritize Your Fixes
The Issue Breakdown section lists each problem type with its count and impact. Start with cliches (they hurt credibility the most) and wordy phrases (they add clutter without value). Passive voice is context-dependent — converting 10-15% of passive sentences to active is usually enough. Weasel words like "very" and "really" can almost always be cut without loss of meaning.
What Good Scores Look Like
A blog post scoring 75+ across all dimensions will feel clear, direct, and engaging to readers. Academic writing typically scores lower on conciseness and adverb discipline by convention. Marketing copy may intentionally use more exclamation and emotional language. The key insight: each context has different standards, and this analyzer gives you the raw data to calibrate your writing to your specific goal.
FAQ
Is this grammar analyzer free to use?
Yes, the Grammar Analyzer is completely free with no usage limits. You can analyze as many texts as you want without creating an account. All analysis happens locally in your browser — no data is ever sent to a server.

Yes, all text processing happens entirely in your browser using JavaScript. Your text is never uploaded, stored, or transmitted anywhere. Close the tab and the text is gone.
How is this different from Grammarly?
Grammarly uses machine learning to catch specific grammar mistakes like subject-verb agreement. This tool focuses on style dimensions: passive voice percentage, weasel word density, wordy phrase frequency, cliche count, and adverb overuse. Together they reveal writing patterns that weaken otherwise grammatically-correct prose.
What are weasel words and why should I avoid them?
Weasel words are vague qualifiers like 'very', 'really', 'quite', 'basically', and 'literally' that weaken your writing. They add length without adding meaning. Replacing 'very important' with 'critical' or 'really fast' with 'instant' makes your writing more direct and confident.
What percentage of passive voice is acceptable?
Most style guides recommend keeping passive voice below 10% for general writing. Scientific and academic writing may legitimately use more (15-20%) since passive construction is conventional ('samples were analyzed'). The tool flags when passive voice exceeds 10% as a moderate concern and 20% as a significant issue.
What are wordy phrases and how do I fix them?
Wordy phrases are multi-word expressions that can be replaced with a single word: 'in order to' becomes 'to', 'due to the fact that' becomes 'because', 'at this point in time' becomes 'now'. Each replacement makes your writing tighter and clearer.
