What this checker does—and does not do

Exact-token checks

Compares numbers, currency values, percentages, placeholders, URLs and email addresses found in both versions.

Claim-risk scan

Highlights Chinese superlatives and guarantees for comparison with the approved source. A match is a review prompt, not proof of an error.

No invented confidence

It cannot judge tone, legal meaning, cultural fit, industry terminology or whether a fluent sentence faithfully preserves the source.

This is a deterministic preflight, not certified translation, legal advice or an AI quality score. Always review regulated, contractual, medical and safety content with a qualified specialist.
