Pangram checker & guide
Pangram is the detector researchers use when they need few false positives. Cosmetic humanizing doesn't work well on it. Real rewriting does.

Independent heuristic estimate of the signals detectors use (predictability, burstiness, stock AI phrasing, repetitive structure). It is not GPTZero, ZeroGPT or Turnitin, and real scores can differ.
Step by step
Paste your draft into the checker above. Note your AI-likeness score and burstiness.
Hover each red sentence to see the signal it triggers, then rewrite it in your own structure.
A number, a source, an example, an opinion. Pangram can't see specificity in a generic draft.
Run the checker again. When most sentences are green, it reads as yours.
What is Pangram?
Pangram Labs builds an AI text classifier that the company says has a very low false-positive rate. It has been used in academic studies that measure AI-generated text in places like peer reviews and online content, and it's available as a web tool and API.
Pangram is trained to recognise text from many models and from common humanizer tools, which makes simple synonym-swapping ineffective.
Want a second opinion on a rewrite? The MultipleChat humanizer (ranked #1 in our humanizer test) lets you compare rewrites from several AI models side by side, then you pick and edit the version that sounds like you.
Other detectors
Teachers and clients often run more than one detector. Fixing the underlying patterns helps with all of them.
FAQ
Pangram reports a very low false-positive rate, and some researchers prefer it for that reason. Accuracy depends on the text type, so check your own case.
Simple humanizers generally don't, because Pangram trains on their output. Substantial human rewriting is what changes the result.
Researchers, publishers and platforms that need to measure AI-generated content at scale.
It offers limited free checks and paid plans and an API. Check its site for current limits.
Use it the right way
AI detectors are probabilistic and get things wrong, which is why it makes sense to check your text first. But the goal is clear, specific writing that is genuinely yours, not hiding AI use where it's banned.
