Built for Contract Translation

Clause-by-Clause Translation

Each clause is translated individually with full context awareness, ensuring no contractual obligations or terms are lost or misrepresented.

Legal Precision

Contract-specific language like indemnification, liability, and force majeure clauses are handled with careful attention to legal meaning.

Numbering Preserved

Section numbers, article references, and cross-references within the contract are maintained for easy comparison with the original.

Signature Page Handling

Signature pages, execution blocks, and witness sections are preserved in their original layout, ready for signing.

Smart Reflow — PDF Only

Smart Reflow: A Better Way to Translate PDFs

Instead of overlaying translations on the original PDF, Smart Reflow extracts content with OCR and rebuilds pages from scratch — producing clean, searchable, editable bilingual documents.

Scanned PDF Support

Translate scanned books and image-only PDFs with advanced OCR text extraction.

Smart Reflow

No overlay artifacts, no text overlap — content is reflowed with clean formatting.

Complex Documents

Handles multi-column layouts, textbooks, and image-heavy academic papers.

Searchable & Editable

Output PDF has fully searchable and editable text — even from scanned sources.

Bilingual & Monolingual

Choose bilingual (source + translation) or translation-only output.

Powered by Large Language Models

AI-Powered Contract Translation

We use the latest large language models — not outdated rule-based engines — to deliver translations that truly understand your content.

State-of-the-Art LLM Models

Powered by the latest AI language models that understand grammar, idioms, and domain-specific terminology far beyond traditional machine translation.

Context-Aware Translation

LLMs read entire paragraphs and chapters, not isolated sentences. This means pronouns, references, and tone stay consistent throughout your document.

Multi-Model Architecture

Different models excel at different languages and domains. Our system automatically selects the best model for your content to maximize quality.

Superior to Traditional MT

Large language models produce natural, fluent translations that read like human writing — not the awkward, literal output of legacy translation engines.
