What the vendor claims, and what we measured

Claim

“HIX Bypass turns AI content generated by ChatGPT, Claude, or Gemini into 100% human score content.” (hixbypass.com , retrieved October 1, 2026) The homepage demo marks ZeroGPT, Crossplag, Content at Scale, Copyleaks, OpenAI, GPTZero, Sapling, and Writer as 100% human written.

Measured

Strict bypass in September 2026: Pangram 2%, GPTZero 68%, Originality.ai 64%, ZeroGPT 100%, Winston AI 98%.

Verdict

Not verified. In September 2026, strict bypass was ZeroGPT 100% against the 100% claimed and GPTZero 68% against the 100% claimed. Crossplag, Content at Scale, Copyleaks, OpenAI, Sapling and Writer are not in this panel.
