Quality that improves every time you use it

This is where Pronto truly stands out. You can review translations directly inside Pronto using a simple, built-in review screen, no extra tools or editors needed. When you upload your final approved files, Pronto learns from your changes and updates terminology and style for the next project. Your setup gets smarter over time, with expert linguists available whenever you need extra assurance.

What is automated post-editing and why it’s worth paying for?

Machine translation only works well when it’s done properly.

At Comtec, we use MTAP (Machine Translation with Automated Post-editing), an expert-led approach where AI translation is automatically refined using rules, resources and quality controls defined by linguists and localisation engineers.

MTAP isn’t a generic engine or a plug-and-play tool. Its quality depends on the expertise behind it, including:

  • How the engine is customised for your content and use cases
  • How terminology, tone of voice and style are applied consistently
  • How content types and markets are handled
  • How output is reviewed and improved over time

When MTAP is set up and managed properly, it delivers translation that is faster and more scalable than fully human workflows, while being far more reliable than raw machine translation.

You’re not paying for “machine translation”.

You’re paying for the expertise that makes it usable for real business content.

Smart MTAP customisation that makes the difference

Pronto isn’t “raw” machine translation, it’s much cleverer than that.


It uses MTAP (Machine Translation with Automated Post-Editing), where our linguists and localisation specialists configure and manage the AI around your brand and markets, so you get more accurate, brand-attuned translations you can rely on.


Here’s what expert-led MTAP customisation looks like in practice:



  1. Terminology & product names are baked in using approved glossaries.

  2. Tone of voice, style and market rules are defined by our linguists and applied through carefully designed AI prompts, covering things like formality levels, punctuation norms and local conventions.

  3. We reuse previous translations and reference content, so phrasing and structure feel familiar.

  4. Language is adapted by market, not just by language, with regional expectations accounted for, for example Swiss French or Lat Am Spanish.

  5. Pronto was built by linguists as well as developers, and the team at Comtec bring decades of experience in translation across industries such as automation, manufacturing, L&D and marketing.

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.

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 isn’t a generic AI tool.

Our linguists and localisation engineers configure and manage the translation setup, including:

  • Applying your terminology and preferred phrasing
  • Defining tone of voice and style rules
  • Handling language variants and regional expectations (e.g. Canadian vs European French)
  • Adapting output by market, not just language

This expert-led setup is what makes MTAP reliable, consistent and suitable for real business use, rather than risky raw MT.

How does Pronto work?

Using Pronto is quick and easy:

  • Log into the Comtec client portal
  • Go to the Pronto area in your dashboard.
  • Upload your files to be translated.
  • Select the source and target languages.
  • Receive AI translations in minutes, with automated post-editing applied
  • Review internally if needed
  • Download your translated files or submit them for optional human review if needed.

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

What’s the difference between Pronto’s MTAP service and linguist review?

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

Linguist Review (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’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.

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

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

How much does it cost?

Pricing is based on:

  • The number of words you translate
  • Which languages you choose to customise
  • Your overall usage volume

There’s a one-off setup and customisation fee for customised languages, followed by per-word usage pricing. Higher volumes benefit from lower per-word rates.

Get in touch and we’ll recommend the most cost-effective option for how you work.

What is the difference between Pronto Lite and Pronto?

Pronto Lite is the standard way to use Pronto. It gives you fast, self-service translation across all available languages, with no brand-specific setup required. It’s ideal for general or lower-risk content and lets you get started straight away.

All Pronto plans include access to Pronto Lite for all supported languages.

When you need more control for certain languages, you can add customisation on a language-by-language basis. For customised languages, our linguists configure terminology, tone of voice and market rules using expert-led machine translation with automated post-editing (MTAP). These languages involve a one-off setup and are charged at a slightly higher per-word rate.

This means you can use Pronto Lite where speed is the priority, and apply customisation only where it adds value.

What is the difference between Pronto and Pronto Pro?

Both Pronto and Pronto Pro provide instant access to fast, high-quality AI translation across our full 30-language offering. The key difference lies in the level of customisation. Pronto (Standard) is trained at a general language level, delivering accurate and high-speed results, making it ideal for high-volume, general content, or as a cost-effective alternative to raw machine translation.

Pronto Pro, however, adds granular customisation in up to five languages of your choice. This means we configure the AI to your specific brand, applying tailored terminology, tone of voice, and workflows to ensure maximum consistency in your key markets. While you can still use the standard Pronto for the remaining languages, the advanced customisation of the Pro tier only applies to your 5 chosen languages.

Do you keep my document layout and tags?

Yes. Pronto is engineered to retain formatting and tags, so exported files drop straight into your workflow without rework.

Can we start without speaking to sales?

Absolutely. Start the free trial to try it yourself. When you’re ready to roll out, choose Sign up and we’ll configure Pronto using the details you provide – no meeting required.
