When a document lacks digital text layers (such as a scanned contract or mobile photo), an OCR engine analyzes pixel grids to identify character glyphs, line baselines, and column structures. It binarizes the image, deskews angled scans, and reconstructs alphanumeric text before passing it to the translation layer.

Traditional dictionary-based machine translation translates words in isolation, frequently resulting in clumsy syntax and laughable mistranslations of idioms. Modern AI translation models utilize deep transformer architectures that evaluate entire sentences and surrounding paragraphs simultaneously. This allows the model to correctly resolve homonyms, adjust grammatical gender agreements, and maintain consistent industry-specific vocabulary throughout the document.

Technical documents require different vocabulary mappings than conversational letters. For example, the French word glace can mean "ice," "mirror," or "ice cream" depending on whether the document discusses refrigeration systems, interior design, or food service. Setting the translation context guides the language model to select accurate domain terminology.

While AI translation provides exceptional accuracy for working drafts, research, and general business correspondence, it does not constitute a certified, notarized, or sworn translation. Official government filings, immigration applications, court evidence, medical records, and patent registrations legally require certified human translators accredited by professional associations (such as the ATA). Never submit raw AI-translated documents to legal authorities without qualified professional human review.
