LanguageCheck.ai is a new tool developed by AQRATE.
AQRATE was founded in 2015 by Marco Baglioni (CEO, with over 30 years of experience in the translation industry) and Michele Fariselli (CTO, with more than 30 years of experience in business application software).
The team also includes language analysts and software engineers.
LanguageCheck is a cutting-edge AI-powered quality checker for human and MT that reduces the effort required for post-editing. It analyzes every segment, flags errors and meaning shifts providing explanations and possible improvements:
- Wide format support: XLIFF, SDLXLIFF, MQXLIFF, XLF, TXLF
- Any language combination supported
- Quality score, XLSX, and online report – clear metrics and shareable results
What users get, sentence by sentence:
- Accuracy check – identifies mistranslations (minor and major mistakes) and shifts in meaning
- Style & grammar review – ensures tone, flow, and correctness
- Terminology control – checks against an approved termbase
- Targeted quality check – highlights only the sentences marked as ‘Needs Improvement’ or ‘Incorrect meaning’, so users don’t need to waste time checking the ‘Flawless’ ones.
LanguageCheck.ai is powered by OpenAI’s language models; the dev team has tested the system on more than one hundred language combinations.
