AI detection tools are intended to help assess whether text may have been generated by AI. The ranking starts with Originality.ai, Pangram, and Winston AI, followed by TraceGPT and Heynotai. Compare language coverage and word limits against the text you expect to review. API access, a browser extension, and report export offer different ways to fit a tool into your workflow; included team seats may matter if you work with others. Free plans and starting prices provide additional points of comparison. Check the listed limits and access options against your languages, review volume, and process.
