Translation Check Lab

It is a practice lab, not a translation service, and it never approves a message.

Machine translation can help draft, but a message that affects safety, health or access to aid needs a qualified bilingual person to check it before it is sent.

Scope

SMS is not confidential. Use this lab only for broadcast messages to groups, never for messages about an individual person.

Language variety

French differs across Canada, Europe and West and Central Africa. Arabic ranges from Modern Standard Arabic to local varieties that OPUS-MT may not match. Consider audio or visual channels alongside SMS for people with low literacy.

Privacy

Text is processed locally by this application. When you choose model download, your browser retrieves model files from the listed third-party hosts. Text is not sent to those hosts by this application.

Limitations

OPUS-MT quality varies by language and domain.

Pattern checks are intentionally conservative and produce false positives. They are prompts for human review, not accuracy measurements.

Tatoeba test sentences are short, general-domain sentences, not humanitarian or medical text, so these scores do not transfer to emergency messages.

Examples of false alarms: a correctly translated French word such as "minutes" flagged as untranslated; a capitalised place name such as "Well 12" flagged when only the capital letter changed in back-translation.

Published model quality by language pair

Benchmark scores are quoted exactly from each upstream OPUS-MT model card on Hugging Face. They are not a guarantee for your message.
