Why customised machine translation matters

Many businesses already use machine translation (MT) in some capacity, and off-the-shelf solutions can be fast and easy but not always the most accurate.

That’s where Pronto is different.

Unlike raw MT engines, Pronto isn’t just plug-in-and-hope-for-the-best. It’s a fully customised machine translation tool trained by professional translators to reflect your tone of voice, terminology, and brand guidelines.

Here’s how it stacks up:
  • Two levels of post-editing: For everyday projects, Pronto Auto Edit comes as standard and offers AI-powered post-editing for speed. When precision matters, you can request Pronto Pro Edit and submit your translations for further review with a highly experienced linguist hand-picked for your project.
  • More than just MT: Pronto blends custom AI engines, translation memory, and advanced LLM-driven post-editing in one powerful tool.
  • Built by linguists, not just developers: The technology team behind Pronto have decades of experience in translation, so linguistic excellence and quality are at the heart of how Pronto works.

Got questions about Pronto? This FAQ answers the most common queries we hear from users, but if you don’t spot what you’re looking for, just drop us a line and we’ll be happy to help.

What is Pronto?

Pronto is Comtec’s self-service customised machine translation tool, designed for businesses that require fast, secure, and cost-effective multilingual content.

It combines advanced AI with your brand’s tone of voice and terminology, ensuring that your machine-translated content receives a brand-specific round of editing as standard, called Pronto Auto Edit, with no extra charge.

If your content requires a bit of extra attention, you can submit it for optional human review via Pronto Pro Edit.

Who is Pronto for?

Pronto is ideal for organisations creating content at scale, including HR, L&D, customer support, product and marketing teams. If you’re working across multiple markets and need consistent multilingual communication without long delays or high agency costs, Pronto is a perfect fit.

What makes Pronto different from other AI translation tools?

Pronto can be fully customised to your brand. That means:

  • It learns and applies your tone of voice and preferred terminology
  • It references any glossary or style guide
  • Local nuances and language variants are supported (e.g. Canadian French vs. European French)
  • Market-specific expectations can be customised, such as formality levels for Spanish, for example, or punctuation norms

These customisations are built into Pronto’s Auto Edit feature, meaning the default output has always been through one round of edits to suit your audience.

How does Pronto work?

Using Pronto is quick and easy:

  • Enter the Comtec client portal (for existing clients, use your regular client portal login details; new clients will be issued login and password details upon sign-up).
  • Go to the Pronto area in your dashboard.
  • Upload your files to be translated.
  • Select the source and target languages.
  • Pronto generates an AI translation and automatically applies your brand preferences with Auto Edit.
  • Download your translated files or submit them for optional human review (Pronto Pro Edit) if needed.

You’ll receive an email alert as soon as your translation is ready to download.

What’s the difference between Auto Edit and Pro Edit?

Pronto Auto Edit (included as standard): This AI-enhanced post-editing layer improves fluency, clarity and tone using your brand-specific settings.

Pronto Pro Edit (optional): This adds a second layer of human review by a professional linguist. It’s ideal for content where nuance, sensitivity or accuracy is critical—such as customer comms or legal documents.

What kind of content is Pronto best for?

Pronto is well-suited to both internal and external content, including:

  • Training and onboarding materials
  • Internal communications with HQ or remote teams
  • RFP and bidding/tender documents
  • Internal policies and HR documentation
  • FAQs, customer support articles and knowledge base content
  • Product descriptions and technical documentation
  • Marketing emails, press releases and campaign content
  • Legal and procurement documentation where clarity and tone matter

Which languages are supported?

Pronto supports more than 30 languages, including all major European, Asian and right-to-left languages. Specific language variants are also available, for example, Brazilian Portuguese or Mexican Spanish. We can add additional languages, depending on your subscription.

Don’t see a language you need? Just ask! We’ll be happy to look into it for you.

What file formats are supported?

Pronto supports all standard editable formats, including:

  • Word, Excel, PowerPoint
  • HTML, XML, JSON, TXT
  • XLIFF, IDML, CSV, SRT

If you have a file type other than the ones we support, please let us know, and we will confirm its compatibility.

How fast is it?

Translations are typically ready within minutes, depending on file size. You’ll receive an automated email once your file is complete and available for download.

If you request Pro Edit, a member of the Comtec team will be in touch ASAP to give you a predicted turnaround time and a quote.

Is my content secure?

Yes. We designed Pronto with data security and privacy in mind.
Your content is never shared with public AI models. All processing takes place in a secure, GDPR-compliant environment, and we’ll support any internal compliance requirements you may have.

What support do you provide?

Comtec provides complete onboarding, training and setup support, including:

  • Uploading and configuring your glossaries and language assets
  • Tailored training sessions (onsite or remote)
  • Prompt engineering to align AI output with your brand
  • Ongoing optimisation and support from our UK-based team

No prior localisation or technical experience is needed; we manage everything for you.

Can we test it before committing?

Yes. We offer a free three-month trial for one language, so you can test Pronto on real content before making a broader commitment.

How much does it cost?

Plans start from £550 per month, depending on your language and usage requirements.

There are no hidden fees or complex tiers, and for a limited time, your first month is free when you sign up for a three-month plan.
