Local AI for technical translation agencies

Short answer

A local model in a translation agency prepares drafts with the selected client's terminology and translation memory, next to the CAT tool, and the text does not leave the agency's environment. It is worth checking whether such drafts cut proofreading compared with the translation memory and the termbase alone.

Translation and AI: statistics 2026

1.2 mo.

payback of a €3,000 local app at 300 translated pages a month: €3,490 of work today, €1,087 with checking and a GPU server. Scenario.

Figures checked: 22 October 2026

Testing drafts in a translation agency
  • The same jobs with the translation memory and with the model
  • The client's terminology in every draft
  • The translator's proofreading time in both variants
  • The client's text stays in the agency's environment

“Housing” in two projects

Say that in client A's approved glossary the word “housing” has the Polish equivalent “obudowa”. In client B's project, in the context described there, “korpus” was approved. The model prepares a draft for B and uses “obudowa”. The sentence sounds natural, and the translator still has to correct it to match this project's resources.

In the proposed view the translator sees which project a segment belongs to and can open the right terminology entry next to the source and the draft. They check the context, change the term and approve the text for the next step. The model helps prepare a proposal; judging technical correctness stays with the people who review the translation. When the glossary does not settle a given use, the question goes back to the person responsible for terminology.

What the translation memory and the termbase already give you

A translation memory stores earlier translations for reuse. A termbase holds the agreed equivalents of words and phrases. The memoQ documentation describes using both resources during translation.

If corrections happen because a project uses the wrong termbase, or approved changes do not reach the team's resources, it is worth tidying that work in the CAT tool first. Adding a model would leave the problem in every following job. Existing memory matches and term suggestions may be enough for repetitive segments.

Local AI is worth considering for segments that need new wording or editing, when the translator wants a proposal that takes the client's resources into account. Switching projects can mean choosing the right material for the app. It does not automatically require separate fine-tuning of the model for each client.

Where the text goes while you work

Say the client has allowed the text to be processed only in a defined environment at the agency. A local model can run on a computer or a server in that environment. Where it runs does not, on its own, describe the document's path through the whole app.

During integration you need to check where files and saved drafts stay and whether the app's activity logs contain pieces of text. A CAT plug-in or an extra service may send content outside that environment.

The person responsible for IT compares the actual flow with the requirements agreed for the project, sets access to the material and decides how support requests that need a look at the text are handled. These arrangements also cover later updates to the integration.

Do the proposals make the translator's work easier?

The comparison should cover the language pair and the documents the team really works with. The translator judges how many changes a proposal needs, whether it keeps the meaning of the source and whether it uses the right client's terminology. Also count the waiting time on the hardware you use and moving text between windows. A shorter correction of a single sentence may not make up for an awkward process across the whole job.

The agency can compare this work with its current way of translating in the CAT tool. The decision needs reviewed proposals and the translators' comments, including examples where they rejected the draft. This shows for which material the integration is useful and what still needs improving before wider use.

The proposed scope for a translation agency

As an AI app, Syntalith can prepare a local workspace linked to the client's resources and an agreed way of passing checked text to the CAT tool. The first scope can cover a chosen language pair, a connection to the project resources available and a view for comparing the source with the draft. How the integration works depends on what your software allows and on the approved data flow.

The agency's team names the corrections that keep coming back and the person who will assess the translations and approve the terminology resources. Together we set the material for the trial, the working environment and later maintenance of the connection to the CAT tool. That way you can look at the proposals in the translator's daily work before widening the scope.

Describe a terminology correction that comes back job after job, the CAT tool you use and where the text may be processed. We can start the conversation from that without sending confidential documents. We price a private model after a free call about the task, the data and the hardware. An app that uses the model starts from €3,000 net (pricing).

What a local model for technical translation costs and when it pays back

Scenario: 300 translated pages a month
Today
300 translated pages × 20 min = 100 h × €34.90 = €3,490
With the app, an employee checks the output in 25% of the time
€873
Hetzner GEX45 GPU server
€214
Saving
€2,403 a month

Payback of €3,000

1.2 months

The volume, the time and the checking share are the scenario's assumptions, which we measure in the trial. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat. Price of the GEX45 with 24 GB of GPU memory from Hetzner's website on 22 October 2026, without the one-off setup fee of €209.

What to agree with IT beyond the model
  • Where the app takes documents from and where it saves results
  • What stays in logs, backups and the history of questions
  • Who has access to questions, answers and summaries
  • Who updates the model, the app and the set of documents

Where to start

In the free process review we choose one task and 20 to 100 documents the team has already worked on, and within 2 working days you get a written summary with a price. We roll out the local model as part of private LLMs, and the app around it as an AI app.

How we count the payback: technical translation

We run the same count for your agency in the free process review.

€3,141

a month for the work on 900 pages

EU cloud version payback: 1.1 mo.

Our assumptions are 6 minutes of a translator's time per page on the task the model takes over, and checking in 15% of the old time. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat, for companies with 10 or more employees. Model cost: Claude Sonnet 5.5, about 6,000 + 500 tokens per answer in the EU cloud version, at the ECB rate of 1.1205 USD per euro on 22 October 2026. We count the payback for an app with a model in the EU cloud (from €3,000 net). We price the model on your server after a call, and the cost of people's work stays the same.

foap.com customer service: 95% of replies are sent automatically.

Users from several countries write to foap.com, in several languages. The system reads the entire conversation and the terms of that person, and then sends a response in that person's language. Questions about money and exceptions go to the team with a ready draft, so they have to check and send them.

We establish a prototype during a free analysis.

Data checked on October 25, 2026.

„Is my data safe?”

Yes. You choose where they go: from your company account to the model on your server.

  1. 00Employee's private account

    Customer and company data ends up in an account that the company cannot see or control. There is no data processing agreement, so it is a violation of the GDPR. When an employee leaves, the chat history goes with them.

  2. 01ChatGPT or Claude corporate account

    The provider does not use your data to train models. A copy of the queries remains in his logs for up to 30 days.

  3. 02API with zero retention (ZDR)

    The provider processes the request and does not save anything. It requires his consent, we prepare the application together.

  4. 03Processing in the EU

    Queries are counted and stored in Europe: OpenAI in the EU region, Claude via clouds with the EU region.

  5. 04Model at your place

    The open model runs on your server or in your cloud in the EU. The data does not go outside the company.

What we do with every implementation

  • Confidentiality agreement and data processing agreement before we receive any data.
  • You choose the cases for the prototype and we anonymize them upon request.
  • The data stays in the EU and we delete it after the test.
  • Corporate accounts with an administrator on your side.

When data cannot leave the company

The open model runs on your server or in your cloud in the EU. To choose from:

Do you have a lot of your own data? We will fine-tune the small model.

  1. 1 Your examples
  2. 2 tuning
  3. 3 test on new cases
  4. 4 model at your place

When you have thousands of similar emails, documents or reports, we teach a small open model based on your examples. It works for you, responds quickly and costs less to maintain than a large model. We measure quality on issues that the model has not seen while learning.

Przemysław and Piotr did it in large programming and consulting companies. Artem did it before and does it today at Syntalith. It's about models on your own infrastructure, tuning and quality measurement.

Questions

  • How does a local model help a translation agency?

    It prepares drafts with the selected client's terminology and translation memory, and the text stays in the agency's environment. The translator corrects the draft in the CAT tool.

  • Is a translation memory enough?

    It is often enough for repetitions. A model makes sense for new sentences where the memory gives no match and the client's terminology has to be kept.

  • How much does an app on a local model cost?

    At Syntalith from €3,000 net plus GPU hardware, for example a Hetzner GEX45 server with 24 GB at €214 a month. At 300 translated pages a month, the payback is 1.2 months.

Let's talk
