Local AI for branches with unreliable internet

Short answer

A local AI assistant helps a branch employee understand a customer's question in another language and put together a short explanation, even without internet. Before you buy, settle whether this help is what is missing most, or whether the branch needs a backup connection to company systems. At Syntalith an app on a local model costs from €3,000 net plus GPU hardware. With 600 conversations in another language a month at 4 minutes each, it pays back in 3.6 months.

Statistics

Languages and AI in companies: statistics 2026

3.6 mo.

payback of a €3,000 local app at 600 conversations in another language a month: €1,396 of work today, €563 with checking and a GPU server. Scenario.

Figures checked: 22 October 2026

The question can be translated, the status has to be checked

The branch has a working internal network and a prepared computer with a model, and the internet has gone down. A customer shows a question: „Is my order ready for pickup?”. The employee types the text into the local app and gets it in their own language, in this example Polish: „Czy moje zamówienie jest gotowe do odbioru?”. They understand what the visit is about.

The order system runs in the cloud and cannot be reached. The employee writes, in Polish, that they have no access to the order system right now and so cannot confirm whether the order is ready. The assistant proposes the English wording: „I can't access the order system right now, so I can't confirm whether your order is ready”. The employee checks the text before showing it to the customer. The assistant does not guess the order status.

What local AI in a branch costs and when it pays back

Scenario: 600 conversations in another language a month
Today
600 conversations in another language × 4 min = 40 h × €34.90 = €1,396
With the app, an employee checks the output in 25% of the time
€349
Hardware in the company, counted in the scenario as renting a GEX45 server
€214
Saving
€833 a month

Payback of €3,000

3.6 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. We price hardware in your own server room after the review.

The count covers the time spent searching, reading and compiling the material. What stays is the time to check the output against the source, 25% of today's work in the scenario. We measure both times in a trial on 20 to 100 cases the team has already handled. The scenario assumes 600 conversations a month across a network of 10 branches. With fewer conversations the payback gets longer, and saved phrases may be enough.

What must stay available in the branch

While the internal network works, the workstations connect to a shared computer in the branch, so access to the model depends on that connection. Ollama describes a local mode without cloud models or web search, and sharing a model on the local network. Several workstations working at once depend on memory and queue handling. The app must open at the start of a shift without internet, together with the sign-in and the saved phrases. The choice between a shared computer and an install at the workstation is covered in local AI on a workstation or a server.

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

When to start with a backup internet connection

If most of the work at the counter needs live data from head office, a local assistant solves a small part of the problem. Meraki describes failover to a backup connection. The behaviour depends on the operating mode and the version, and switching over can come with interruptions. If conversations during an outage come down to a few messages, approved translations at the counter or an offline translator are a simpler start. A model is worth testing when customers' questions vary.

Where to start

The work starts with one branch and chosen languages. The branch manager brings examples of conversations, and a person who knows both languages judges whether the proposals keep the meaning. We roll out local models as part of private LLMs, and we build the view for working with sources as an AI app. For the free process review, a description of one case and the places where the material sits is enough. Confidential files stay in the company, and you get a written plan within 2 working days.

How we count the payback: customer service

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

€5,817

a month for answering 2,000 customer emails

Payback: 0.6 mo.

5 minutes to read an email and write a reply and checking in 15% of the old time are our assumptions. €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 3,000 + 600 tokens per message with a draft reply, at the ECB rate of 1.1205 USD per euro on 22 October 2026.

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:

White-tailed eagle
Polish model, SpeakLeash and ACK Cyfronet AGH
PLLUM
Polish model, HIVE consortium commissioned by the Ministry of Digitization
Qwen
Alibaba
GLM
Zhipu AI
DeepSeek

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

  • Does local AI translate without internet?

    Yes, when the model, the app and the sign-in run on the branch computer. It cannot check statuses from cloud systems, so the employee tells the customer about the outage.

  • A backup connection or a local assistant?

    It depends on what employees do during an outage. When they wait for data, a connection helps. When they hold conversations that need language help, an assistant helps. Some branches need both.

  • How much does such 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. With 600 conversations in another language a month, the payback is 3.6 months.

Let's talk

Just write, call or choose a date.

We work fast because we hate corporate cotton wool. We don't have salespeople or managers to keep an eye on managers. You talk immediately to engineers who then build your system. We respect each other's time and yours too.

We will accept 3 more companies by the end of the year.
