Products Private translation

Translate text and documents on your own hardware, with nothing leaving the machine.

MetaLex is a locally hosted translation platform. It translates reliably into more than 100 languages, with wider coverage of over 400, keeps the layout of Word and PowerPoint files intact, and reads scans and PDFs. Everything runs on your own GPU hardware with outbound access disabled.

Speeds are measured on NVIDIA DGX Spark, the most compact system MetaLex runs on. Server-grade hardware is faster still.

Translation that fits the way you work

Paste, detect, translate

Enter or paste text and MetaLex detects the source language automatically. Choose Speed for a fast answer or Quality for the most polished result, and ask for a summary in the target language when you need the gist rather than every word.

  • Automatic source-language detection
  • Speed and Quality modes
  • Summaries written in the target language, as brief or as detailed as you need
  • Paste a screenshot or choose an image to read its text before translating

Documents come back looking like documents

Word and PowerPoint files are translated in place, so layouts, themes, images and formatting survive. Every paragraph is translated with the whole document in view, keeping terminology consistent from the first page to the last.

  • Slide text, tables, charts and speaker notes are all translated
  • PDFs, scans and photos of pages are read and returned as editable Word documents
  • An optional summary in the target language alongside the translation
  • Documents are private to their owner and deleted automatically after 24 hours

An audit view for an offline install

The System view shows which components are running and how many languages are available, and keeps a full record of every installed component, ready for an assurance review.

  • A live status for every part of the system
  • A full record of every installed component
  • Clear guidance on where translation quality is strongest

Accurate translation, whatever the language

MetaLex combines two translation engines and automatically uses whichever handles each language best.

Automatic

The right engine, every time

Each language pair goes to whichever engine translates it best. Users never have to choose.

400+

Wide coverage when you need it

Beyond the 100+ languages it translates reliably, over 400 are available, so less common languages are never turned away.

Auto-detect

No need to know the source

The original language is identified automatically, even in short or uncommon text.

Consistent

Whole-document context

Every paragraph is translated with the whole document in view, so names and terminology stay consistent from start to finish.

Scans + photos

Reads scans and PDFs

Scanned pages, PDFs and photos of documents are read first, then returned as editable Word files.

The gist

Summaries in the target language

Concise summaries for when you need the point rather than every word, alongside or instead of a full translation.

Built for confidential and privileged material

Documents sent for translation are often confidential and sometimes legally privileged. MetaLex is mapped to the NCSC Cyber Assessment Framework, Secure by Design and the UK codes of practice.

  • Sign-in for every user, and a secure token for every script
  • Encrypted connections through a single entry point
  • No route to the internet from any part of the system
  • Every document opened in an isolated, tightly limited sandbox
  • Text translations are never stored, and documents are deleted after 24 hours
  • No telemetry, and no third-party scripts or fonts
  • A signed, verified installation package
  • Fair sharing, so short requests never wait behind a long document

Runs on the hardware you choose

  1. Start small with DGX Spark

    MetaLex is optimised for NVIDIA DGX Spark, a compact desk-side system that is all a team needs to get started.

  2. Scale up to the data centre

    It runs just as well on DGX workstations and data-centre GPU servers such as the NVIDIA B300, provided there is enough GPU memory, and gets faster with every step up. We can help you choose.

  3. Installed offline

    Prepared once on a connected machine, then installed on your closed network from a signed, verified package. MetaLex and MetaVox can share a single machine.
