AIAI Text Watermark Checker

Transparent by design

How the checker reaches a result

Every result is separated by evidence type. Literal characters are deterministic. Provider conclusions require an official verifier. The product does not infer authorship from formatting.

Literal Unicode

Deterministic

Exact code-point matching for zero-width characters, direction controls, Unicode tags, special spaces, control codes, and related formatting artifacts.

Visible lookalikes

Review only

Mixed-script characters are reported for manual review. The cleaner does not rewrite visible letters or guess the intended character.

Provider watermarks

Adapter required

A provider conclusion appears only when an official supported verifier is connected. An unavailable result is never reported as not detected.

File provenance

Inspection roadmap

C2PA, EXIF, XMP, and document properties require format-aware inspection. We will report provenance separately and will not silently strip authenticity records.

Reproducible core

The literal scanner is available as a dependency-free MIT-licensed package with tests, TypeScript types, and a CLI. Review it on GitHub or install it from npm.
