Choose the Workflow That Fits Your Needs

At ALTA, we offer two flexible AI-powered localization service options, as well as a 100% human-powered option to align with your budget, content sensitivity, and quality expectations.

AI Translation with Light Post-Editing

This three-step process uses AI-generated translation, followed by light editing from a professional, native-speaking translator with subject-matter expertise to correct errors and improve clarity, and a final quality check before delivery.

AI Translation with Full Post-Editing

This premium option goes beyond the light post-editing process by adding a second level of human review by a subject-matter expert. After the initial review, a second native linguist performs a thorough proofread to refine tone, nuance, and precision—ensuring the text reads as if originally written in the target language.

While there is no universally-accepted translation certification, ALTA offers a notarized certification attesting to the accuracy and completeness of a translated document, which is sufficient in most cases. Our certification is typically accepted by courts, though we encourage clients submitting court documents to check the requirements with their specific court and situation. We are not affiliated with or endorsed by any specific court/jurisdiction.

ALTA maintains strict confidentiality through a comprehensive information security program that protects client content. Our secure infrastructure includes enterprise-grade encryption for data both in transit and at rest, role-based access controls that limit content access to only essential personnel, secure file transfer protocols, and regular security awareness training for all team members who handle client materials. We enforce strict non-disclosure agreements with all employees and contractors, maintain detailed audit logs of all document access, and implement rigorous data handling procedures that align with industry best practices. We would be happy to review a client NDA, or provide our standard client NDA for your review, if needed.

Our notarized certification is generally accepted by courts or government agencies, but we strongly advise checking with the specific agency to make sure – we are happy to send you an example of what our certification looks like.

We serve healthcare, legal, finance, education, government, marketing, HR, and more. Our robust pool of seasoned translators allows us to match any project with the right subject matter expert.
