The Strategic Choice: Mercurio™ vs. Generic AI
Most business owners use generic tools like Google Translate or DeepL for quick tasks.
But for corporate operations in the USA, Uruguay, and Brazil, the “good enough” approach often leads to costly technical errors.
Why choose our AI translation services?
Feature | Generic AI (Google/DeepL) | Mercurio™ by TranSlate |
|---|---|---|
Terminology | Generalized patterns. | Dynamic Retention: Industry-specific glossaries are “locked” into the engine. |
Privacy | Data is often used for training. | Zero-Knowledge: Your documents remain private; they are never used to train public models. |
Cultural Nuance | Literal word conversion. | Region-Aware: Handles the “False Friends” between English, Rioplatense Spanish, and Brazilian Portuguese. |
Reliability | High risk of “hallucinations.” | Human-in-the-Loop: Every AI output is verified by a native expert for technical accuracy. |
Why “Terminology Retention” Matters to Your Bottom Line
Generic AI tends to “smooth over” technical language to make it sound natural, but in sectors like Legal, Finance, and Engineering, “natural” isn’t enough—it must be precise.
- USA ↔ Uruguay: Mercurio™ understands the specific nuances of US Common Law vs. Uruguayan Civil Law.
- Brazil Expansion: We don’t just translate into “Portuguese”; we localize for the specific commercial landscape of São Paulo and Porto Alegre.
- Speed: Get 10,000 words of boardroom-ready technical content in under 48 hours.
- Simultaneous Contextual Processing: Beyond human memory limits, Mercurio™ maintains a ‘Universal Knowledge Base’ for your project—applying industry-specific terminology, regional localization, brand tone, and complex manuals of style simultaneously across thousands of pages with zero drift.
Proven results:
Larger or more specialized projects are scheduled with extended timelines, always with a clear quote before starting.
The Mercurio™ advantage:

We trained a linguistic AI for a year and a half to achieve today’s incredible results.
