TheChecker.AI
Freemium · $9.90/moAI text detector with a humanizer and an MCP connector for Claude
What is TheChecker.AI?
TheChecker.AI scores a piece of writing for the likelihood that it came from models such as Claude, GPT-5 or Gemini. It is pitched at students, teachers and writers who want to check work before submitting or grading it, and it shows results down to individual paragraphs.
An analysis reports an overall AI probability along with perplexity and burstiness measures, and you can paste text or upload PDFs and other documents. A separate humanizer rewrites text flagged as machine-written, paid for with word credits that do not expire.
Both the detector and the humanizer are exposed as tools over the Model Context Protocol, so you can connect them to Claude or another MCP client with OAuth and use the same account limits there. Schools and teams can ask for an enterprise setup with LMS integration and bulk user management.
