Pangram is an AI detection service for analyzing text and images for signs of generative-AI assistance. It is designed for educators, publishers, businesses, and other users who need to assess content authenticity alongside plagiarism.
What is Pangram?
Pangram is an AI detector for text and images. It analyzes structural, stylistic, and semantic patterns in writing to identify likely AI-generated content from models including ChatGPT, Claude, Gemini, Grok, and Llama, and it also offers image detection.
The service is built for content-authenticity workflows in education, publishing, media, and business. In addition to an overall assessment, it can indicate how much of a document appears AI-generated, identify passages showing AI assistance, and check for plagiarism in the same workflow. Text can be pasted, dragged and dropped, or uploaded; the homepage also supports image uploads.
What can Pangram do?
Image detection
Checks uploaded images for signs of AI generation. The homepage lists JPG, PNG, and WebP uploads, with a minimum size of 512×512 pixels and a maximum file size of 30 MB per image.
AI segment analysis
Reports not only an overall confidence assessment but also how much of a document appears to be AI-generated, giving reviewers a more granular result.
AI assistance highlighting
Highlights text segments that may have been edited with AI rather than treating the entire document as fully AI-generated.
Plagiarism checking
Combines plagiarism detection with AI detection so users can check text authenticity and potential copied content in one workflow.
Multilingual analysis
The site states that its AI detection works across more than 20 languages, supporting use by institutions and businesses working with multilingual content.
Use Cases
“Review student work”
Teachers and schools can use text analysis as one input when reviewing essays or other assignments, then use segment-level results to discuss possible AI assistance with students.
“Support editorial and publishing review”
Editors and publishers can assess submitted articles, drafts, or documents for likely AI-generated passages and potential plagiarism before publication.
“Investigate content transparency”
Media and communications teams can add an AI-origin check to workflows where readers, clients, or stakeholders need clearer information about how content was produced.
“Check business documents”
Businesses can review internal or externally supplied writing for AI involvement and plagiarism when evaluating documents, reports, or other written materials.
“Screen visual content”
Users can upload supported image files to check whether visual material may have been AI-generated, alongside the service's text-analysis workflow.
