Research preview
Test rewriting without confusing a proxy score for proof.
This opt-in lab exposes every candidate, preserves the original, rejects broken invariants, and reports inconclusive results instead of manufacturing certainty.
Experimental
Iterative rewrite lab
Generate up to three local wording variants, verify basic invariants, and compare an open statistical proxy. Your original always remains available.
Proxy-scored experiment. Lower scores do not prove a provider watermark was present or removed, and do not prove human authorship.
The local proxy is a reproducible research control, not Anthropic, SynthID, OpenAI, Turnitin, or another provider detector. Fewer than 200 scored tokens remain inconclusive.
Turn on the experiment for this run
Existing scanning and lossless cleaning stay unchanged.
