Pangram Labs makes an AI detector that checks whether text was written by a person or generated by a language model. Paste or upload a document and it reports how confident it is that the writing is AI, plus how much of the document is affected through segment analysis. It also flags passages edited with AI assistance, runs plagiarism checks, and scans images for AI generation. A free plan covers up to 2,000 words per day, while the Individual plan costs $20 per month and Professional costs $65 per month.
Teachers, professors and school administrators use it to verify student submissions, and editors and publishers use it to screen articles before they run. Researchers, recruiters, law firms and compliance teams who need to confirm authorship are a natural fit as well. Developers can reach the detector through an API, which the free plan includes. Individual writers and freelancers can check their own drafts before sending them to clients. Because it supports more than 20 languages, it works for international classrooms and multilingual newsrooms, and a browser extension covers text found anywhere on the web.
Common scenarios include grading essays, reviewing freelance submissions, moderating user-generated content, and auditing a content team's output. Pangram integrates with Google Docs and Gmail, so a writer can scan inside the apps they already use. The Individual plan can automatically scan a feed on social media or Substack. File upload with OCR handles scanned documents, and past scan records remain available for reference. The company reports accuracy of 99.7% across 26 benchmarked models and cites verification by researchers at the University of Maryland and the University of Chicago.
