🔍 AI Content Detector

Checking if your content sounds human or AI-made can be tricky, especially with tools like ChatGPT, GPT-4, Claude, and Gemini. This free online detector makes the process easier by checking six writing signals, including AI-style phrases, sentence patterns, formal vocabulary, passive voice, and word variety. It gives you an AI probability score from 0 to 100, along with a detailed sentence analysis map. You can quickly see which parts of your text look more AI-like and understand why they were flagged. No sign-up is needed, and your submitted text is not stored, logged, or shared. Longer texts can also provide more useful results.

💡 Notable Features

What sets MiniWebtool apart?

🤖 AI Probability Score

Get a simple score from 0 to 100 that shows how strongly your text matches common AI writing patterns. The tool checks several signals before creating the result. This makes it easier to review content quickly and decide which parts may need a closer look.

🔎 Six Signal Analysis

The detector checks six different writing signals, including AI-style phrases, sentence uniformity, transition overuse, passive voice, formal vocabulary, and vocabulary diversity. Looking at these patterns gives you more useful context than relying on a single basic AI detection signal.

📝 Sentence Analysis Map

See which individual sentences show stronger AI-like patterns with a clear visual map. Each sentence receives its own analysis, helping you spot specific areas that may need editing. This is especially useful for longer articles where only certain sections may contain AI-assisted writing.

📊 Detailed Signal Breakdown

Go beyond the final score with a breakdown of the patterns found in your content. You can see which phrases, sentence structures, and word choices influenced the result. This gives you practical information for improving the text instead of simply receiving a score.

🔒 Private and Simple

You can check your writing without creating an account or going through a complicated setup. The tool is free to use, and MiniWebtool states that submitted text is not stored, logged, or shared. That makes it convenient for quick content checks when privacy matters.

👨‍🎓 Expert's Opinion

what does our expert say about MiniWebtool?

MiniWebtool’s AI Content Detector is a useful option for getting a quick idea of how much AI-like writing appears in a piece of content. I tested it with different types of text, and the sentence-level analysis stood out. It does more than provide one overall score. You can see which sentences trigger AI signals and why. The six-point analysis also makes the results easier to understand. It is free, requires no sign-up, and keeps the process simple. One drawback is that the results are not definitive. Formal, academic, or heavily edited content may sometimes be flagged incorrectly. Still, it works well as a helpful screening tool.
