Local AI for document review before a process change
Short answer
Before a process change, a local AI assistant searches the text of instructions and forms for every reference to the element being changed and shows each one with its line, version and source. An engineer assesses every place, and the documents never leave the company's environment. At Syntalith an app on a local model costs from €3,000 net plus GPU hardware. With 40 process changes a month at 90 minutes each, it pays back in 2.2 months.

payback of a €3,000 local app at 40 process changes a month: €2,094 of work today, €738 with checking and a GPU server. Scenario.

According to Bartanowicz and Jassem (LREC 2026), in a RAG system on Polish technical documentation assessed on 146 reference questions, Bielik-11B-v2.3-Instruct consistently beat PLLuM-12B-nc-chat.

According to a Syntalith measurement (2026), Qwen3.8-27B on an RTX 3090 card recalled 3 of 3 checked facts from an input of 230,085 tokens, and the run took 563.4 seconds.

One change, references in many documents
An engineer prepares a change and looks for the instructions and forms that may need updating. Searching by file name is not enough when the references to a fixture sit in the text. An example: on a packing line the label of a fixture changes. The work instruction and the inspection form still carry the old label, and the company requires these documents to be processed in its own environment.
The assistant finds both passages and shows them with the line name, the version and a link to the source. The engineer opens the documents, judges whether the reference needs changing and records the finding at the place found. Until the change is approved, the existing documentation applies. The app does not publish new instructions and does not decide the technical scope of the change.

What local AI for manufacturing documentation costs and when it pays back
- Today
- 40 process changes × 90 min = 60 h × €34.90 = €2,094
- With the app, an employee checks the output in 25% of the time
- €524
- Hardware in the company, counted in the scenario as renting a GEX45 server
- €214
- Saving
- €1,357 a month
Payback of €3,000
2.2 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. 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. With 40 changes a month at 90 minutes of searching for references, the count covers one person running changes in a mid-sized plant.
What runs locally and what needs agreeing
The model runs on a named computer or server in the company. What remains to agree is how documents are read, where the material prepared for search is stored and where findings are recorded. Where the model runs does not describe the whole path of a file through the app. A trial on the target hardware covers several people working at once and the time from a question to a checked source. According to Bartanowicz and Jassem (LREC 2026), on 146 questions about technical documentation in Polish, Bielik-11B led among the models compared. The choice of model is still settled by a trial on your own documents.
- 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 your current register of links is enough
If the document management or product data system already links the fixture to its instructions and forms, those links are a good starting point. A more convenient review view or completing the register may be enough. AI is worth testing when the references sit in free text and the register does not lead to those places. Finding the approved version is covered in the article on local AI for formulation versions.

Where to start
The first scope covers one line and an agreed set of instructions and forms. For the call, describe the last change where related documents were hard to find. 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: a local model in manufacturing
We run the same count for your documentation in the free process review.
€5,817
a month for the work on 1,000 questions
EU cloud version payback: 0.6 mo.
Our assumptions are 10 minutes to find the right instruction, 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.
