Signals are not proof
A writing checker may look at sentence-length variation, repeated words, connector patterns, punctuation rhythm, and common template phrases. These are observable features of a text, not evidence of who wrote it. A careful human writer can produce regular prose, and an AI-assisted draft can contain personal, irregular language.
Why scores change
- Short samples are unstable. A few sentences do not contain enough variation for a meaningful comparison.
- Language matters. Korean, English, and other languages have different sentence boundaries, spacing rules, and common connective phrases.
- Editing changes the signal. Rewriting, translating, combining sources, or adding quotations can change the pattern without changing the origin.
- Different tools use different references. A score from one detector cannot be compared directly with a score from another.
A responsible way to use a checker
- Use a substantial sample that you are allowed to analyze.
- Read the explanation behind the result instead of treating the number as a verdict.
- Compare the output with your own drafts, notes, sources, and revision history.
- Ask for human review when the result could affect a grade, job, admission, or accusation.
Document Forge's deliberately narrow result
The browser analyzer reports an interpretable reference score based on writing patterns. It labels confidence based on sample length and lists contributing signals. It does not identify authorship, detect plagiarism, or guarantee that a text was or was not produced by AI. Text stays in the browser for this default analysis; an optional server model is not active on the public preview.
