TraceGPT

What TraceGPT is

TraceGPT checks writing for signs of AI generation, scoring each sentence from 0 to 100 and highlighting sentences it flags. Its report can combine those results with plagiarism matches, source links, highlighted passages and an originality score, and reports can be downloaded as PDFs. AI detection is available in English and Spanish; similarity checks cover 15 languages. The company says the detector is trained and tested on models from Google, Anthropic, OpenAI and xAI, and reports 99.23% sentence classification accuracy across seven tested models. It also notes that humanized or hybrid writing is harder to detect. TraceGPT is available on the web, through browser extensions and via an API. The free plan and short-text checker provide a way to try it; individual plans include Basic at $5.99, paid once for 20 pages, Light at $9.99, paid once, Standard at $25.49, paid once and Premium at $45.49, paid once. API use requires an account and token, accepts English only, and rejects text under 80 characters.
