AI PDF Translator
Free for the first 1,000 credits
AI-Powered PDF 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We use the latest large language models — not outdated rule-based engines — to deliver translations that truly understand your content.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 GPT-4, DeepSeek, Claude, and other leading models. These LLMs 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.
