The record

Purpose: Isgen describes itself as a multilingual AI detection company that helps users assess whether content is AI-generated.
Detection analysis: The detector provides an overall Human, AI, and Mixed score, with sentence-level and phrase-level analysis and color-coded highlights.
Languages: The maker says its AI content detector supports over 80 languages.
Models: The site says the detector is trained to identify outputs from models including ChatGPT, GPT-5, Claude, Gemini, DeepSeek, and Llama.
File input: Users can paste text or upload files individually or in bulk for scanning.
Reports: Paid plan feature comparisons list shareable and downloadable reports.
Other tools: The site lists a plagiarism checker, grammar checker and proofreader, AI humanizer, AI editor, citation generator, bulk scan, image detector, and video detector.
AI Editor: The AI Editor combines drafting, editing, proofreading, humanizing, and real-time AI score updates; the homepage says users can start free without signing up.
Intended users: The maker names students, researchers, educators, academic institutions, content creators, journalists, professional writers, authors, business professionals, and legal professionals as audiences.
Accuracy caveat: Isgen states that AI checkers are not 100% accurate and advises educators not to penalize students based on detector results alone.
Data handling: The homepage says Isgen does not store data, while input history is maintained for paid users and can be deleted at any time.
Plan limits: Unused words do not roll over to the next month, and cancellation leaves premium access active until the billing cycle ends before downgrading to Freemium.
