AI translation tools can be useful for basic content, but professional translation is recommended for legal, technical, medical, financial, academic and business documents where accuracy, confidentiality and cultural nuance are essential.

Professional linguists can identify ambiguities, apply specialised terminology, adapt content to the target audience and ensure that the final translation is suitable for its intended purpose.

We offer both professional human translation and AI-powered translation services.

Depending on your requirements, we can provide fully human translation, AI translation with professional post-editing (MTPE), or a customised solution that balances quality, speed and cost.

The most appropriate solution depends on the type of content, language combination, volume, deadline and required level of quality.

Our AI-powered translation services combine advanced language technology with the expertise of professional translators. We use carefully selected AI translation tools to accelerate the translation process, improve consistency and reduce turnaround times, while ensuring quality through human review.

Depending on the project, AI-generated translations can be revised, edited or fully post-edited by experienced linguists who verify terminology, accuracy, tone and cultural appropriateness.

This hybrid approach is particularly effective for high-volume content, such as product descriptions, technical documentation, knowledge bases and business communications.

The result is a faster, more cost-effective translation solution that combines the speed of AI with the quality assurance of professional human translators.

Turnaround times depend on the language combination, subject matter and volume of content. Your quotation will include an estimated delivery date.

If your project is urgent, let us know when requesting a quotation and we will do our best to accommodate your deadline.

You can send documents by email, secure file transfer services, cloud storage platforms, post, courier, USB drive or flash drive.

For a quotation, we normally need to see the documents or receive sufficient information about the content, language combination and required deadline.

Translation costs depend on the source and target languages, subject matter, document length, file format and required turnaround time.

Our quotations are transparent and provided in advance, so you know exactly what to expect. In most cases, pricing is based on the number of words in the source text, with no hidden fees.

Additional services, such as formatting, OCR, proofreading, certification or urgent delivery, may affect the final price.

You can pay in cash, by bank transfer or via PayPal.

Certified translations are often required for immigration, legal, academic and administrative purposes. We can arrange certification by a lawyer or notary public, provide a translator's declaration when appropriate, and obtain an apostille under the Hague Convention if required.

Certified translations must be based on original documents or certified copies where required. Certification requirements may vary depending on the document and the authority receiving it.

Usually, yes. We recreate the original layout as closely as possible, including fonts, formatting, tables, images, headers and footers.

Minor adjustments may be needed because some languages require more or less space, use different fonts or follow different layout conventions, such as Arabic and Hebrew.

If a specific format or page count is essential, let us know. For official documents, we carefully reproduce the original appearance and structure wherever possible.

Yes. All documents are treated as strictly confidential and handled securely throughout the translation process.
