What is Translation Quality Assessment Tool?

Translation Quality Assessment Tool is an analytics tool. A free web tool from Tomedes that compares source and translated text, then scores accuracy, fluency, terminology, style, grammar and completeness. It flags untranslated and missing segments, builds a bilingual glossary, checks term consistency and produces a downloadable report.

The Translation Quality Assessment Tool is a free browser based checker from Tomedes that compares a source document with its finished translation and returns an objective quality score. Paste both texts or upload the files, and the engine reports word counts on each side, the languages it detects with their share of the text, and whether the target is noticeably longer or shorter than the source. That ratio alone often exposes padding, omission or a segment that was never translated. The scoring breaks down into five categories: accuracy, fluency, terminology, style and grammar. Each gets its own grade plus an overall mark out of 100, so a reviewer can see at a glance whether a problem is one of meaning or one of polish. Alongside the scores, the tool marks untranslated terms left in the source language, flags segments that are missing entirely, notes passages that need correction, and confirms differences that are contextually justified. A bilingual glossary is generated from the text, and a consistency checker surfaces terms rendered several ways in the same document. The tool is aimed at the people who actually sign off on translations: freelance linguists doing post-editing or a second pass, localization project managers auditing vendor deliveries, and in-house teams that need to prove compliance without buying enterprise QA software. It is equally useful for judging raw machine translation, since the report shows whether an engine's output needs heavy post-editing or is close to deliverable. Tomedes positions it as a lightweight companion to full LQA programs rather than a replacement for human review. The automated pass handles the mechanical checks and gives reviewers a starting point, but sign-off on nuance and cultural fit still depends on a linguist. Files can be uploaded in DOCX, PDF, XLSX, PPTX, HTML, SRT and other common formats up to 15 MB, or text can be pasted directly into the editors.

Pros and cons

Pros

  • Produces an overall score out of 100 plus separate category grades for accuracy, fluency, terminology, style and grammarAI
  • Flags untranslated terms, missing segments and inconsistent term usage instead of only returning a numberAI
  • Free to use with no account or credit card requiredAI
  • Accepts pasted text or uploads of DOCX, PDF, XLSX, PPTX, HTML and SRT files up to 15 MBAI
  • Useful for judging machine translation output before committing to a post-editing budgetAI

Cons

  • The scoring is automated, so subtle tone and cultural nuance still need a human linguist's judgementAI
  • The 15 MB per file cap will block very large localization projects, which then need splittingAI
  • No pricing or plan details are published, so it is unclear how the free tool relates to Tomedes' paid human servicesAI
  • Only English language documentation appears on the page, which limits guidance for non-English reviewersAI
