Dechecker - 2026 Pricing, Features, Reviews & Alternatives

Dechecker is a web-based AI content detection platform that identifies AI-generated text from models including ChatGPT, GPT-5, Claude, Gemini, and LLaMA. Operating on a freemium model, it requires no installation or registration for basic use, making it accessible to students, educators, freelancers, content creators, and small teams. Submissions of up to 20,000 characters are supported per check, accommodating long-form documents such as academic papers, blog posts, and professional reports. Detection methods include token probability analysis, sentence entropy measurement, sentence uniformity detection, semantic coherence metrics, and repetition pattern analysis, with results delivered as per-segment confidence scores and sentence-level highlighting of flagged content.

Beyond detection, Dechecker integrates an AI Humanizer that rewrites flagged sections in a single workflow, removing the need for separate tools. Bulk file upload supports multi-document processing, and a detection history feature allows users to revisit past reports. Results can be exported as downloadable PDF reports or shared directly for team or client collaboration. Text submitted for analysis is not stored, protecting sensitive content including academic assignments and confidential business documents. Guest users receive up to five checks per day without sign-up; registered users unlock monthly credits for extended access.
