TraceGPT
Summary
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 USD per once for 20 pages, Light at 9.99 USD per once, Standard at 25.49 USD per once and Premium at 45.49 USD per once. API use requires an account and token, accepts English only, and rejects text under 80 characters.
Who it is for
TraceGPT may suit educators, students, SEO writers, editors, newsrooms and professional services that need sentence-level AI checks or plagiarism details in the same report. It also offers integrations for learning platforms and browser-based workflows.
