structrans is an online AI-powered document and structured file translation tool built for content managers, software developers, and localization teams.

Standard translation tools like Google Translate or DeepL web upload frequently break Word document margins, distort PDF table layouts, or corrupt code variables ({user}, %s, {{id}}) in JSON and localization files.

structrans solves this with a syntax-aware parser and context-aware LLM translation engine. It extracts only human-readable text, translates it with high accuracy across 20+ languages, and reconstructs the output file with zero formatting or code breakage.

Key Benefits: โ€ข Layout & Formatting Preservation: Translates DOCX, PDF, and PPTX files while preserving exact typography, table borders, and page margins. โ€ข Code Syntax & Variable Safety: Protects ICU placeholders, template variables, HTML tags, and nested keys in JSON, PO, ARB, XLIFF, and YAML files. โ€ข Privacy-First Processing: 100% in-memory processing โ€” confidential corporate documents are never stored on disk or used for AI model training. โ€ข Instant Access: Free browser-based translation with no credit card or account registration required.

Questions & Answers

As answered by people managing LibreTranslate and structrans.

What makes your product unique?

structrans's answer:

structrans uses syntax-aware and layout-aware AST parsing. Instead of treating files as raw text, it extracts only human-readable strings, translating copy via LLMs while preserving 100% of document margins, tables, and code variables ({user}, %s, {{id}}).

Why should a person choose your product over its competitors?

structrans's answer:

Unlike generic translators (Google Translate, DeepL) that distort document formatting and break code variables, or enterprise TMS platforms (Lokalise, Crowdin) that cost 100โ€“500$/mo and require complex setup, structrans offers instant, zero-friction web translation with zero layout corruption and a free tier.

How would you describe the primary audience of your product?

structrans's answer:

Content managers translating corporate Word (DOCX) and PDF documents, software developers localizing app i18n files (.json, .po, .arb, .xliff), and marketing teams needing fast, layout-preserved document translation.

What's the story behind your product?

structrans's answer:

We got frustrated after repeatedly seeing standard web translators destroy Word document tables and break template variables during software release cycles. We built structrans to give developers and content managers a simple, privacy-first tool that translates files cleanly without ruining code or layout.

Which are the primary technologies used for building your product?

structrans's answer:

Built on Cloudflare Workers edge runtime, Astro, React, and powered by high-accuracy LLM translation engines combined with custom document AST parsers and LibreOffice/Tesseract OCR layout processing.

Who are some of the biggest customers of your product?

structrans's answer:

structrans is primarily used by indie software developers, digital marketing agencies, content managers, and remote international startup teams translating i18n locale files and business documents across 20+ languages.
