Watermark checking
The free checker reviews supported text-layer watermark-like and provenance signals. It does not mix cleanup or general Unicode findings into the report.
HOW TEXTTRACE WORKS
Focused checks, evidence-first results.
Each tool answers one question, shows its supporting evidence, and keeps responsible conclusions in view.
Invisible character inspection
The Pro inspector locates supported zero-width spaces, joiners and related characters, including their code points and positions.
Unicode cleaning
The Pro cleaner normalizes supported hidden characters, spacing and markup artifacts while preserving visible wording as closely as possible.
Responsible interpretation
A detected signal is evidence to review, not a conclusion about authorship or AI use. No result proves the absence of an unsupported provenance system.
