Pangram vs Plagium

Pangram detects AI-generated text and images and offers plagiarism detection. Its text analysis covers material associated with ChatGPT, Gemini, Grok, Llama, and Claude, and it can highlight passages edited by AI rather than fully generated by AI. Users can submit PDF, DOCX, and RTF files, with uploads of up to 100 files at a time. Pangram says its detection works across more than 20 languages. A Chrome and Firefox extension scans feeds on sites including X, LinkedIn, Substack, Medium, Reddit, and Google Docs; listed integrations also include Canvas, Blackboard, Brightspace, Google Classroom, Moodle, Schoology, and Ashby. Pangram says submitted content is not used to train generalized AI models. Text remains stored while an account is active but can be deleted from dashboard history. The service has a free plan and a 7-day trial. Individual costs $20 per month billed annually, and Professional costs $65 per month billed annually. The site displays SOC 2 Type 2 verification by AssuranceLab.

Plagium analyzes text for similarity with other material and offers a separate tool for identifying patterns compatible with AI-generated writing. Its plagiarism service compares submitted text with an online database and reports similarities with links to original sources. The AI Detector uses statistical and probabilistic analysis of writing patterns. Deep Search accepts Microsoft Word, PDF, and native text files; Google Drive integration and a Google Docs add-on support document analysis. Institutional users can access an API, while business solutions can integrate with corporate CRM, ERP, and document-management systems. Plagium presents solutions for educational institutions, publishers, editors, companies, researchers, and compliance teams. The free account costs nothing and allows five daily searches with a 4,000-character limit, but excludes Deep Search and API access. Plagium says submitted content remains owned by the user and is processed for analysis, report generation, and service improvement. Reports are automated estimates rather than definitive proof, and private, unpublished, or non-indexed material may not be detected.
