Checking a piece of writing takes only a few seconds. The tool is clean, easy to follow, and gives you an answer right away. Here's how to use it.
Step 1
Drop in the text you want checked. You can scan up to 1000 words at a time, and run as many scans as you need.
Step 2
Type the numbers shown in the captcha box and press the "Detect AI Text" button.
Step 3
The tool analyzes your text in the background and shows you a percentage score along with the exact sentences that look AI written.
Instead of handing you a single confusing number, Pangram AI Detector breaks a result down so you actually understand it. Paste your text, run the scan, and see exactly which sentences read as AI generated and which ones don't. It's built for people who need a real answer, not a guess.
The flagged sentences are highlighted right inside your text, so you know exactly which part triggered the score instead of guessing.
A scan takes a few seconds. There's no waiting around and no queue, you get an answer while you're still reading this sentence.
Your text is used only to run the scan and isn't saved anywhere on the server once the result is shown to you.
There's no account wall between you and your result. Open the page, paste your text, and check it.
More writing than ever is coming out of a chatbot rather than a person sitting down with a blank page. That's fine for a lot of casual uses, but it becomes a real problem the moment someone needs to know for sure. A teacher grading essays, an editor reviewing a submission, a hiring manager reading through applications, all of them run into the same question sooner or later. Pangram AI Detector was built to answer that question quickly and honestly, without asking you to sign up or pay for the privilege.
Plenty of AI checkers exist already, but most of them stop at a single number and leave you to figure out what to do with it. This tool takes a different route. It doesn't just tell you a percentage, it shows you which sentences actually caused that percentage, so you're not left guessing which part of a document needs a second look.
Pangram AI Detector is a free tool that scans a piece of text and estimates how likely it is that the content was generated by artificial intelligence. You paste your text into the box, run the check, and within a few seconds you get a score along with a highlighted view of the specific sentences that read as machine written.
The idea behind building it this way was simple. A bare number doesn't help much on its own. Knowing exactly where a piece of writing shifts from natural to formulaic is far more useful, whether you're checking a student's homework or your own draft before sending it off.
The tool looks at patterns that tend to show up in AI generated writing, things like sentence rhythm, word choice, and structure that a person usually doesn't repeat the same way twice. Once it finishes analyzing your text, it puts together a percentage score and marks the sentences that pushed that score up.
This matters more than it might seem at first. A document that's mostly human written but has one AI assisted paragraph shouldn't get treated the same as something written entirely by a chatbot. Sentence level detail is what tells the two apart.
Using it is about as simple as it gets. There's no learning curve and nothing to configure before your first scan.
There's more than one reason people keep coming back to this tool rather than switching to something else.
Teachers and instructors are an obvious fit, since checking a stack of assignments by hand for AI writing just isn't realistic anymore. Editors and content managers use it as a first pass before publishing freelance work. Students and writers use it on their own drafts too, sometimes just to confirm a piece reads the way they intended before turning it in.
Really, anyone who needs to know whether a piece of text was written by a person or a machine can get something useful out of running it through this tool. It doesn't require any technical knowledge, and the result is easy enough to read at a glance.
No AI detector is perfect, and Pangram AI Detector doesn't claim to be an exception. Short pieces of text don't give the model much to work with, and content that's been heavily edited after being drafted by AI can land somewhere in the middle. Treat the score as a strong signal that points you in the right direction, not a final ruling handed down without room for judgment.
AI writing isn't going anywhere, and pretending otherwise doesn't help anyone. What actually helps is having a quick, honest way to check a piece of text when it matters. Pangram AI Detector gives you exactly that, without the paywall, the sign up form, or the vague single number that leaves you no better off than before you ran the check.
Whether you're a teacher, an editor, or a student checking your own work, Pangram AI Detector gives you a clear, sentence level answer instead of a single confusing score.
