🤖 AI-Powered Translation vs Google Translate for PDFs
Google Translate's PDF feature works — but it's optimized for casual text. SalesInt uses OpenAI's GPT-4o-mini, the same model behind ChatGPT, which has significantly stronger performance on:
- Business and legal language — formal register, contractual phrasing, industry terminology
- Technical documents — product manuals, API documentation, engineering specs
- Nuanced sentences — idiomatic expressions, conditional clauses, passive constructions
- Long documents — maintains context and consistency across multi-page reports
🔬 The technology behind it
SalesInt extracts raw text from your PDF using pdf-parse, sends it to GPT-4o-mini with language-pair instructions, and reconstructs the translated output as a downloadable PDF using pdf-lib. The entire pipeline runs in under 10 seconds for most documents.
