Upload your document, choose the service level and receive a verified translation in minutes
Try Vertio NowVertio is the self-service document translation platform developed by M21Global. Upload your file, select the language pair and service tier, and receive a translation that has been automatically verified for accuracy. No accounts to manage, no waiting for quotes. Pay only for what you use.
Translating a document is easy. Knowing whether the result is correct is the real challenge. Vertio combines AI translation engines with an automated verification layer that compares outputs, detects inconsistencies and generates confidence scores, so you can trust the result before you use it.
Built on more than 20 years of professional translation experience and over 300 million words delivered, Vertio brings the rigour of ISO 17100 and ISO 18587 certified processes to a simple, on-demand interface.
Vertio is a web platform where you upload a document and receive a translated version in minutes. The process is straightforward: select the source and target languages, choose a service tier, upload your file and pay. Vertio handles the rest.
What sets Vertio apart from free online translators is the verification layer. Instead of simply running your text through a single engine and hoping for the best, Vertio can compare the output of two independent AI translation engines, flag segments where they disagree and highlight potential issues. The result is a translation you can use with greater confidence.
For projects that require human expertise, Vertio also offers access to M21Global's professional translators, with delivery in 24 to 48 hours. One platform, five service levels, from fully automated to fully human.
Vertio offers five distinct service tiers, each designed for a different use case:
Draft (EUR 2 per 1,000 words) — single AI engine, delivered in 1 to 3 minutes. Ideal for internal documents, quick comprehension checks or content where speed matters more than polish. Good enough to understand the meaning; not intended for publication.
Normal (EUR 9 per 1,000 words) — two independent AI engines translate your document separately. Vertio compares the outputs segment by segment and selects the best result for each. Delivered in 3 to 10 minutes. This is the recommended tier for most business documents: reports, presentations, emails, product descriptions. The dual-engine comparison catches errors that a single engine would miss.
Plus (EUR 9 per 1,000 words) — everything in Normal, plus a detailed quality report with confidence scores per segment. You see exactly where the translation is strong and where it might need a second look. Ideal for reviewers, quality managers or anyone who needs to sign off on translated content.
Human Translation (custom pricing) — your document is translated by a professional native linguist from the M21Global team. Delivery in 24 to 48 hours depending on volume. For content that will be published, submitted to regulators or shared with clients, this tier provides the reliability of professional translation services.
ISO 17100 (custom pricing) — full human translation with independent review and quality certification, following the ISO 17100 standard. The complete TEP process (Translation, Editing, Proofreading) for documents where compliance, accuracy and traceability are mandatory: contracts, regulatory filings, medical documentation.
Vertio accepts the most common document formats: .docx, .pptx, .txt, .json and .md, with a maximum file size of 50 MB and up to 20,000 words per document. The original formatting is preserved in the translated output, so you receive a file that is ready to use without manual reformatting.
Currently, Vertio supports 14 active languages: Portuguese, English, Spanish, French, German, Italian, Dutch, Polish, Russian, Danish, Ukrainian, Romanian, Swedish and Finnish. More than 70 additional languages are planned for future releases.

Your documents contain sensitive information. Vertio was designed with privacy as a core requirement, not an afterthought.
No AI training: your content is never used to train translation models. Once your document is processed and delivered, it is not retained for machine learning purposes. Your data remains yours.
Private processing: each translation is handled in an isolated environment. Documents are not shared between users, not accessible to other clients and not stored beyond the time needed for delivery.
GDPR compliance: Vertio follows the data protection principles established by the European General Data Protection Regulation. Data minimisation, purpose limitation and security by design are built into every step of the workflow.
M21Global has been handling confidential documents for more than 20 years, including legal contracts, medical records and financial reports. Vertio inherits that same commitment to security and confidentiality.
Free online translators give you a result in seconds, but with no verification, no formatting preservation and no guarantees. You copy, paste, hope for the best and spend time checking whether the output is actually correct.
Professional translation agencies deliver certified quality, but the process takes days: briefing, quoting, scheduling, reviewing. For many documents, that timeline and cost structure are not practical.
Vertio fills the gap. You get a verified translation in minutes, with formatting intact, at a predictable per-word price. No subscriptions, no minimum commitments beyond a EUR 10 top-up that remains valid for 12 months. Pay for what you use, when you use it.
When the stakes are higher, you can escalate to Human Translation or ISO 17100 directly within the same platform, with access to the full resources of M21Global. One starting point for every translation need, from a quick internal draft to a certified legal document.
Vertio is built by a company with ISO 17100 and ISO 18587 certification, audited by Bureau Veritas. The technology is new; the expertise behind it has more than two decades of track record and over 300 million words delivered.
Vertio is designed for simplicity. You access the platform at vertio.ai, upload your document, select the language pair and service tier, and pay. The minimum top-up is EUR 10, which remains available in your balance for 12 months.
The Draft tier uses a single AI engine and costs EUR 2 per 1,000 words. It is fast (1 to 3 minutes) and suitable for understanding the general meaning of a document. The Normal tier uses two independent AI engines, compares their outputs segment by segment and selects the best result. It costs EUR 9 per 1,000 words, takes 3 to 10 minutes and delivers significantly higher accuracy. For any document you plan to share externally, Normal is the recommended choice.
No. Your documents are never used for AI training. Each file is processed in a private, isolated environment and is not shared with other users or retained for machine learning. Vertio follows GDPR data protection principles, and M21Global has more than 20 years of experience handling confidential content under strict security protocols.
Vertio offers two human-powered tiers directly on the platform. Human Translation assigns your document to a professional native linguist, with delivery in 24 to 48 hours. ISO 17100 adds independent review and certification, following the full TEP process. Both are handled by the M21Global team, the same professionals who serve enterprise clients through our translation services.
Vertio currently supports .docx, .pptx, .txt, .json and .md files, up to 50 MB and 20,000 words per document. There are 14 active languages: Portuguese, English, Spanish, French, German, Italian, Dutch, Polish, Russian, Danish, Ukrainian, Romanian, Swedish and Finnish. More than 70 additional languages are being added progressively. For formats or pairs not yet available, contact M21Global directly.
