Agency vs AI vs SealScribe: Clinical Translation Compared

Anyone who needs to translate a protocol, an informed consent form, or a package insert today effectively has three paths: a traditional translation agency, generic AI (ChatGPT, Google Translate, and the like), or a tool built specifically for the regulated sector, like SealScribe. Each one solves part of the problem and ignores another — and picking the wrong one costs time, confidentiality, or terminological precision, depending on which part got ignored.

This guide compares all three paths without sugarcoating anything: where each one is strong, where each one fails, and how to decide which one fits your document.

Traditional agencies: safe, but slow

A traditional translation agency, with a specialized human translator, is still the safest standard in terms of terminological precision and contractual confidentiality — when the translator actually has experience in the regulatory domain. The problem isn’t quality: it’s speed. The process is usually sequential — translator, then reviewer, then formatter — and each stage waits for the previous one to finish. A correction midway sends the document back to the start of the queue.

For documents of 50,000 words or more, that means weeks, not days — a timeline that doesn’t always fit a regulatory submission or a multicenter study’s schedule.

Generic AI: fast, but no terminology control or confidentiality

A generic AI translation tool processes the same document in minutes — speed isn’t the problem. The problem is that it wasn’t built for this domain: it has no locked official glossary (MedDRA, DCB, ANVISA’s Controlled Vocabulary), doesn’t know that Brazilian regulation now requires “participante da pesquisa” instead of the older “sujeito de pesquisa”, and treats each segment of the document independently — which produces terminological inconsistency within the text itself.

More critically: most generic AI tools process the text in the provider’s cloud, with no prior anonymization. For a protocol containing patient or site data, that’s, in practice, a data protection problem — not just a translation quality one.

The middle ground that was missing

SealScribe exists because neither path alone solves the problem for people translating clinical research and regulatory affairs documents: the traditional agency is safe and slow; generic AI is fast and imprecise (and risky on confidentiality). The pipeline runs anonymization before any sensitive data reaches the cloud, locks an official glossary per document, and adds review before delivery — stages that run in parallel, not in a queue, cutting time without giving up terminology control.

Direct comparison

When each option makes sense

• Traditional agenciesstill make sense for sworn/certified translation (which SealScribe doesn’t offer) or when timeline isn’t a real constraint.
• Generic AIworks well for internal use, quick drafts, or material that won’t be submitted to an ethics committee and contains no sensitive data — never for the final document of a regulatory submission.
• SealScribe was built for the case where confidentiality, regulated terminology, and timeline all need to coexist — the most common scenario in clinical research and regulatory affairs.

How to decide

The right question isn’t “which tool is better” in the abstract — it’s “what does this specific document require”. If it contains sensitive data, is headed to an ethics committee or a regulator, and needs to be ready in days, not weeks, the combination of anonymization, an official glossary, and review stops being a nice-to-have and becomes the minimum requirement. That’s the problem SealScribe was built to solve.
