Document translation that uses the client’s context. Two independent engines translate in parallel, and verification points to the places that need a decision.
Live service: translateincontext.com for the international market, xl8.pl for Poland.
Our own Localize.pl project, not client work.
Machine translation knows the sentence but not the situation. In a bicycle service manual, “Tighten the nut to 12 Nm” is about a fastener, and no engine will guess that unless someone tells it what the document is.
Translate in Context is built for companies and translators who need document translation with terminology control and with insight into why the translation reads the way it does.
The application first analyses the document and reference material, then shows an editable context draft. The user corrects the assumptions before translation starts, so a misreading of the document does not repeat in every segment.
Every segment is translated in parallel by two engines from different vendors. A verifying agent compares the proposals and discrepancies go to resolution. Review focuses on the places where a decision is actually needed.
Terms from TBX and CSV glossaries are also enforced by a plain, deterministic comparison. Terminology consistency does not depend on whether the next model response happens to remember them.
The translation comes with a report that explains the decisions and lists the fragments that could not be resolved automatically.
The Polish version, xl8.pl, adds a step with the Polish Bielik model to polish the Polish text. Both versions share one application.
| Technology | Role |
|---|---|
| Next.js, React, TypeScript | Order flow, context work and result review |
| PostgreSQL, Prisma | Jobs and translation process state |
| Vercel, Vercel Blob | Application hosting and document storage |
| Language models from two vendors, Bielik | Translation, verification and resolution; Bielik in the Polish version |
| TBX, CSV, XLIFF, TMX | Glossaries in, export to CAT tools out |
| Paddle, Autopay and KSeF | International payments; payments and invoicing in Poland |
The service is live in two market versions and still being developed. We describe only what is available today. Rebuilding complex document formatting has its limits, and the decision report is there to make human review faster, not unnecessary.
