Great writing is not just about what you say — it is about how you say it. Nielsen Norman Group research shows that users scan rather than read web content, making readability optimization essential. Is your content readable? What tone does it convey? Are you using too many filler words? Is your keyword density optimal for SEO? These questions used to require expert review or expensive tools. Now, AI text analysis can answer all of them in seconds.
Our AI Text Analysis platform offers 40 specialized tools that evaluate every dimension of written content — from readability and grammar to sentiment, accessibility, and even literary style. This guide shows you how to use each category effectively.
AI text analysis uses natural language processing models to evaluate and understand written content. Unlike simple spell checkers, these tools understand context, tone, audience appropriateness, and linguistic patterns. They can tell you not just what is wrong with your text, but how to make it stronger, more engaging, and more effective for your specific goals.
Visit AI Text Analysis and select a tool based on what you want to evaluate. Not sure? Start with the Readability Score for a quick quality check.
Copy and paste the text you want to analyze. It can be anything — a blog draft, an email, a product description, a school essay, or a social media post.
Use the notes field to specify your target audience, goals, or concerns. "This is for a professional LinkedIn audience" or "Targeting 8th grade reading level" helps the AI give more relevant recommendations.
The AI delivers structured analysis with specific scores, examples, and actionable recommendations.
Understanding how easy your content is to read is fundamental:
For web content, aim for a Flesch-Kincaid grade level of 6-8. For technical documentation, 10-12 is acceptable. The Readability Score tool makes it easy to check and adjust.
Understanding the emotional impact of your writing:
These tools are invaluable for reviewing customer communications, marketing copy, and any content where tone matters. Run your email through the Tone Detector before sending to make sure it conveys the impression you intend.
For content marketers and SEO professionals:
The Keyword Density tool is essential for SEO writers. Paste your article, optionally specify target keywords, and get a complete analysis of how naturally your keywords are distributed and whether you need to adjust usage.
Improve your writing mechanics:
For the most thorough writing review, run your text through the Grammar & Style Checker first, then use the Passive Voice Detector and Weak Word Replacer for focused improvements.
Ensure your content works for all audiences:
If you write for a global audience, the ESL Complexity Analyzer is essential. It identifies idioms, phrasal verbs, and advanced grammar that may confuse non-native speakers and suggests simpler alternatives.
For creative writers and literature students:
Specialized detection tools:
Lighthearted analysis tools:
Analyze before publishing. Make text analysis the last step in your writing workflow. Run a final check through the Readability Score and Grammar Checker before any content goes live.
Know your target scores. For general web content, aim for a Flesch reading ease score of 60-70 (easily understood by 13-15 year olds). For academic content, 30-50 is appropriate.
Use multiple tools together. A Readability Score check followed by Sentiment Analysis and Keyword Density gives you a complete picture of your content's quality, tone, and SEO effectiveness.
Do not blindly follow every suggestion. AI recommendations are guidelines. Sometimes passive voice is intentional, or a complex sentence serves a purpose. Use your judgment alongside the analysis.
Test on real content. The best way to learn is to analyze your own published content. Paste a successful blog post or email and see what the tools say about it — this teaches you what works in your specific context.
You can analyze text of any reasonable length — from a single sentence to a full article. For the most useful analysis, paste at least a few paragraphs to give the AI enough context for meaningful evaluation.
Start with the Grammar & Style Checker for a comprehensive review. Then use the Readability Score to check complexity and the Tone Detector to verify your voice.
Yes. The Readability Score, Grammar Checker, and Content Gap Analyzer are all useful for academic papers. The ESL Complexity Analyzer is especially helpful for students writing in a second language.
Your text is processed by the AI model for analysis only and is not stored permanently or shared.
Whether you are optimizing for SEO, polishing a business email, checking accessibility, or exploring the literary qualities of your creative writing, there is a specialized analysis tool for your exact need.
