CertOf

CertOf provides certified document translation for immigration, education, legal matters and other official uses. Its online workflow combines AI-assisted translation with professional human review and revision while preserving the source document’s layout. Customers can review a preview before payment. After payment, a professional translator reviews the full translation against the source, including content, key fields, terminology, formatting and certification wording. Paid translations include a Certificate of Translation Accuracy, online certificate verification and unlimited human revisions. CertOf serves customers online, with a team presence in Los Angeles and Beijing.

Our workflow is AI-first and review-backed. Document recognition and layout understanding come before translation. Names, dates, numbers, amounts, seals, stamps, signatures, handwriting, tables, headers, footers, and low-confidence fields are checked through AI validation, external reference lookup, human review, user preview, and unlimited revisions. CertOf is useful for birth certificates, marriage certificates, diplomas, transcripts, court records, medical records, immigration documents, scanned files, and complex layouts. Some files take longer: multi-page files, complex layouts, low-quality scans, rare languages, or fields requiring confirmation.
