DetectAI for Educators →Check your own writing before publishing. If you used AI to draft, make sure the final version reads naturally and won't be flagged.
DetectAI for Writers →Screen submissions and freelance content for AI-generated text. Identify pieces that may need additional human editing before publication.
How Detection Works →Check your own essays before submitting to make sure they don't accidentally trigger AI detectors. Verify that your AI-assisted drafts have been sufficiently rewritten.
Humanize Your Writing →If your text scored high on the AI detector, here are proven methods to make it read naturally.
AI writes in uniform sentence patterns. Mix short punchy sentences with longer, more complex ones. Start some sentences with conjunctions. Fragment others.
Manual — takes 15-30 min per pageWords like "furthermore", "it's important to note", "in today's digital landscape" are AI tells. Replace them with simpler, more natural alternatives.
Manual — requires good vocabularyAI text is generic. Add specific examples, personal anecdotes, opinionated statements, and concrete numbers. Make it sound like a real person wrote it.
Manual — hardest to do wellTools like WriteKit's AI Humanizer automatically restructure your text, replace AI patterns, and inject natural variation. Results in seconds instead of hours.

DetectAI uses heuristic analysis of 6 text patterns commonly found in AI-generated content. It catches the most common tells: uniform sentence structure, AI-typical phrases, overuse of transition words, and more. No detector is 100% accurate, but ours provides a reliable signal for most content.
No. All analysis happens entirely in your browser using JavaScript. Your text is never transmitted anywhere. This is a client-side tool with zero server communication.
If your text scores above 40%, it likely contains patterns associated with AI writing. You can rewrite it manually, or use a tool like WriteKit's AI Humanizer to automatically make it sound more natural.
DetectAI analyzes writing patterns common across most large language models including ChatGPT, Claude, Gemini, and others. The patterns may vary by model, but the overall tendencies are similar.
Teachers can use AI detection tools like DetectAI to check for common AI writing patterns. ChatGPT tends to produce uniform sentence lengths, overuse transition words like "furthermore" and "moreover", and follow predictable paragraph structures. However, no detector is foolproof — heavily edited AI text may pass undetected, and some human writing can trigger false positives.
Yes, completely free with no limits. We don't collect emails, require signup, or have a paid tier for detection. The tool runs entirely in your browser at zero cost.
WriteKit's AI Humanizer rewrites your text to sound naturally human. It bypasses GPTZero, Turnitin, Originality.ai, and every major detector. Free to use, no account needed.
