Why Developers Choose Bluente for RAG Workflows
Generic translation APIs return plain text, stripping the structure that RAG pipelines depend on. When financial tables lose their rows or legal numbering collapses, your retrieval models ingest corrupted context, and your outputs become unreliable.
Bluente's document translation API is built for file-based workflows. It preserves tables, charts, headers, footnotes, and formatting across 22 document formats including PDF, DOCX, PPTX, XLSX, HTML, XML, and DITA. Advanced OCR handles scanned and image-based files, converting non-selectable text into clean, structured, translatable content.
For teams in legaltech, financial services, insurtech, edtech, healthcare, or enterprise operations, Bluente delivers translation outputs that are immediately ready for ingestion, review, and downstream processing. Backed by SOC 2, ISO 27001:2022, and GDPR compliance, sensitive documents are processed securely at scale.

Bluente's translation API supports 22 file formats including PDF, DOCX, DOC, PPTX, PPT, XLSX, XLS, HTML, HTM, XML, DITA, EPUB, SRT, EML, INDD, AI, XLF, XLIFF, PNG, JPG, and JPEG. This broad format support makes it well suited for RAG pipelines that ingest diverse document types from multiple sources.
Bluente uses a layout-aware translation engine that retains tables, charts, images, footnotes, headers, footers, legal numbering, and styling from the original file. Unlike generic text-based APIs, Bluente processes the full document structure, ensuring translated outputs are structurally identical to the source and ready for immediate ingestion into RAG pipelines or downstream review workflows.
Yes. Bluente includes advanced OCR that converts non-selectable text in scanned PDFs and image files (PNG, JPG, JPEG) into editable, searchable, and translatable content. The document structure is preserved throughout the OCR and translation process, making it reliable for processing legacy files, scanned reports, or image-based records in your pipeline.
Bluente supports translation across 100+ languages, enabling cross-border workflows for global teams. Whether you are processing multilingual financial reports, legal filings, compliance documentation, or product content, Bluente provides high-quality translations while maintaining the original document layout and data integrity.
Yes. Bluente is SOC 2 compliant, ISO 27001:2022 certified, and GDPR compliant. The API uses end-to-end encryption for all data transfer and applies automatic file deletion after processing. These controls make Bluente suitable for processing sensitive material including contracts, financial reports, medical records, and regulatory filings.
Yes. Bluente's API supports batch upload, allowing you to submit multiple documents in a single request. You can track the status of all jobs in real time and receive webhook notifications upon job completion. This makes it practical for high-volume RAG pipelines that process large batches of multilingual documents continuously.
Standard translation APIs accept plain text strings and return translated strings, discarding all formatting. Bluente is a file-based translation API that accepts uploaded documents and returns fully translated files with their original structure intact. This distinction is critical for RAG pipelines where document structure, table data, and layout context must be preserved for accurate information retrieval.
Bluente's API is designed for developers and engineers across legaltech, financial services, insurtech, edtech, healthcare, ecommerce, and enterprise operations. Any application or pipeline that needs to process, translate, and ingest complex multilingual documents while preserving formatting and maintaining data integrity can benefit from integrating Bluente.
