Frequently asked questions
How is this different from the AI Content Detector?
The Detector gives you a pass/fail AI score. The Writing Checker goes deeper — it breaks down 6 specific AI patterns and gives you actionable suggestions.
What does the percentage score mean?
A score of 15% AI means 15% of your text exhibits AI-like patterns. Anything under 20% typically passes all major AI detectors.
Can I use this to improve my writing?
Yes. Each flagged passage includes specific suggestions for making it read more naturally — vary sentence length, add personal voice, use less predictable transitions.
What are perplexity and burstiness?
Perplexity measures how predictable your word choices are. Burstiness measures variation in sentence length. AI text typically has low perplexity and low burstiness.
Is there a word limit?
Free tier allows up to 1,000 words per check, 3 checks per day. Premium removes all limits and adds exportable PDF reports.

AI Writing Checker is built for a wide range of users. See how it fits your needs.
