TRY ITPangram
Pangram checks text and images for signs of AI generation. It is used by educators, publishers, trust and safety teams, developers and other organizations that need to review large amounts of submitted content.
Paste text into the web app or upload a document and Pangram returns an overall classification. It also highlights individual passages as human-written, AI-assisted or AI-generated. That passage-level view is more useful than a single percentage when a document contains a mixture of original writing and AI edits.
The current Pangram 4 model was built to recognize newer language models, humanized output and writing that moves between human and AI authorship. Pangram publishes model cards and evaluation reports for people who want to examine its methodology rather than rely on a marketing accuracy figure.
The AI image detector checks uploaded JPG, PNG and WebP files and returns a human or AI classification with a confidence result. Free accounts receive a small daily image allowance, while paid plans increase the monthly limit. Enterprise image detection is also available for higher-volume verification work.
Paid individual and professional plans can run plagiarism checks alongside AI detection. Matching passages are highlighted and linked to possible sources. Schools and universities can connect Pangram to learning management systems, while the browser extension and Google Docs integration bring checks into everyday review work.
Developers can add Pangram to moderation queues, publishing systems and internal review tools through its API. The response includes document-level predictions, separate fractions for human, AI-assisted and AI-generated text, and character ranges for each detected section. Realtime and discounted bulk processing are available.
No AI detector can establish authorship on its own. A result should prompt a closer look at the document, its revision history and the surrounding evidence. This matters most in education, recruitment and other settings where a false accusation carries a real cost.
Pangram has a free plan with daily text and image limits. Paid plans add larger allowances and plagiarism checks. Options for teams, institutions, developers and enterprises cover shared administration, LMS connections, API usage and higher processing volumes.
