Pangram

Pangram is an AI-content detector for schools, universities, and enterprises. It analyzes submitted text (or images) to estimate whether content is AI-generated, AI-assisted, or human-written, and it can highlight which parts look AI-edited.

It’s a good fit if you need results you can share with others, like instructors reviewing student work or teams moderating or verifying user-submitted content.

• Text and image detection. Run checks on pasted text and also upload images for AI detection.
• AI-assistance segment analysis. Get more than a single label by showing how much of a document looks AI-assisted and highlighting segments.
• Plagiarism checker in the same workflow. Run plagiarism and AI checks together for a combined “authenticity” view.
• Multi-language support. Works across 20+ languages.
• Integrations for institutions. Available via a browser extension and integrates with learning tools like Google Docs and LMS platforms such as Canvas and Google Classroom.
• API for high-volume use. Supports an API option for organizations and developers.
• Verified accuracy claims. The site states third-party evaluation (including university research) focused on low false-positive rates.

For usage, Pangram supports file uploads (including PDF, DOCX, and RTF for document checks) and offers free scans on a daily basis, then credits or subscription options beyond that.
