Smodin

Smodin's AI Content Detector scans pasted or uploaded text (.txt, .doc, .docx, .pdf) and returns an AI-vs-human probability score with sentence-level highlighting, flagging the specific passages that read as machine-generated. The vendor advertises 99.8% accuracy, sub-2-second scan times, and coverage across 100+ languages including Spanish, Portuguese, and Swedish, positioning the tool for essays, research papers, marketing copy, and general documents rather than one narrow use case. Smodin also markets it as an "AI watermark checker," though the product itself is clear that this means pattern-based detection of AI-writing signals (repetitive phrasing, uniform sentence rhythm), not cryptographic verification of a provider's hidden watermark.

Detection runs on Smodin's own machine-learning models trained to recognize the statistical fingerprints of output from ChatGPT, GPT, Claude, Gemini, and similar systems, rather than checking against a single vendor's API. The company states submitted text is not stored or shared, and results come back as an overall percentage plus per-sentence flags a user can act on directly, without needing to interpret a raw confidence number.

The detector is one tool among several inside Smodin's broader platform, which also includes an AI Humanizer, a Plagiarism Checker, an AI Writer, an AI Chat assistant, an AI Mock Interview/cover-letter toolkit, a rewriter/spinner, a text summarizer, and a translator, all behind the same login and the same Starter/Premium subscription. That bundling is the main thing to understand before buying: Smodin is not a company built solely around detection the way a specialist product is, and the detector's feature set and tier gating are shaped by that broader multi-tool platform rather than existing as a standalone product line.
